Enduroboxer…

Yes, what about it? The first BMW R80G/S? The airhead that jump-started the career of dualsport motorcycles and dominated the Paris-Dakar Rally? 

Yes, that one, on steroids! Or on a diet..? I’m not sure, let’s get into it! 

Intro

Inspired by German legends Fritz Witzel, Eddi Hau, and Herbert Schek, Manuel had the idea to enter an 800cc airhead into an enduro rally for twins >500cc. Not the obvious choice, since the airheads are neither particularly lightweight nor particularly powerful. Especially the ones that were originally assigned to the German Police Force. So what did Manuel do to this battleship of a bike to allow him to race in the enduro class and even become German national champion in the Interessengemeinschaft Enduro (IGE) class? 

The donor bike

He acquired the former Augsburger bike and reinforced the frame to allow for the abuse he was about to put it through. He designed, cut, and welded reinforcements to the steering head, the top tube, and to the swingarm attachment points. Then, he swapped the original twinshock for a later model paralever. This reduces the reactionary forces of the drive shaft construction and allows for the use of a centrally mounted rear shock. The top of that shock mounts to the main frame, rather than to the rear subframe, which was common standard on the original twinshock airheads. The current subframe Manuel built himself, and hosts the Maico seat and the SR Racing muffler, another weight saver. The elongated design allows for sufficient padding and shifting weight easily in rough terrain. A Preston Petty MX fender prevents the mud from collecting on top of the bike.

The modifications

At the front, all mid-1970’s components have been swapped out for more modern, high-performance parts. A WP AER fork sits in reinforced CNC aluminium triple clamps. These too Manuel designed and produced inhouse. Just behind that sits an aluminium petrol tank, kindly donated by a Husqvarna. The engine sits centrally in the frame and Manuel heavily modified it to suit his needs. Most obvious are the additional oil-cooler, the rerouted exhaust headers, and the hefty bash-plate. Yet something is off when you look at it. If you look closely, you will find that he ground off the top of the engine case, timing cover, and front engine cover to save weight. It currently boosts 880cc and puts out sufficient grunt to get Manuel across the finish line first. It’s not comparable to what a modern 900cc engine would put out in terms of power, but remember that these engines were engineered to be very rideable. They put out an impressive amount of torque across the rev range. And that is saying something! Especially when you consider that Manuel stands over 2 metres tall. Perhaps that’s the secret to his success. He found a niche where he can combine his height, his talent, and his wrenching skills, and compete at the top level. When you see him on his enduroboxer, he whips it around like a dirtbike!

Put to action

What makes the bike so special is that it has been built to ride, and that it is ridden. For many years now it accompanies Manuel at sport events, and they have experienced many highs and lows together (pun intended!). They have ridden the Erzberg Rodeo, Le Tourquet, and the many IGE enduro competitions. And still, it makes him happy to ride! About the bike in his own words [translated from German]: “The motorcycle rides great, it is really fun. One should not forget though, that I built it specifically for myself, and that I massively modified it over the years. A bike so fitting, I would never have been able to buy off the shelf.”

Inspired?

Now if this has tickled your fancy, or if one of our earlier posts about enduro or dualsport boxers did, get in touch with Manuel. During the week when he is not winning on the track, he is giving it his best in the shop. Over 130 frames have been straightened and/or reinforced by their hands. And if you look closely, you will start to see Manuel’s work in many other motorcycles. Frame modifications, custom builds, and parts, SWT-Sports is a one-stop-shop for getting the airhead of your dreams, especially when you’re looking beyond a bobber or cafe racer!

Moto Adonis
We have seen a couple of incredible builds from the workshop of Moto Adonis. The Dutch builders, which consists out of Arthur Renkema and Job Leussink, have been busy the last couple of years. Who remembers the menacing Harley Davidson LiveWire? Or the BMW RnineT Girder? Only a few months later, they’ve already announced the culmination of 2 more projects. One of which is the BMW R80 dubbed “BIG Dude”, the bike we will be discussing further below.

Popular Bike
In all honesty, we can list the factory bike specs here again, but that would be pointless at this stage. Yes, the BMW R80 is probably the most popular motorcycle to use as a base bike for a myriad of projects. Be it a café racer, scrambler, tracker or even a resto-mod; there is something about the simplicity of the airheads that inspires creativity. But there is more to it than that. The overall build quality and availability of new parts, considering the fact that these aren’t new motorcycles, inspires confidence.

Project “BIG Dude”
It was no different with this build. A customer called the workshop and asked a simple question: “Can you build me a BMW R80 Scrambler?”. The answer Arthur and Job had for him was “Sure!”. All seemed fine, until the customer paid them a visit. It became clear that they needed to take a few things into consideration. The “biggest” one being the customer’s size. The dude was bigger than most BMW riders, measuring in at 2 meters, the builders knew that they had o make some serious modifications to allow for a bigger rider to enjoy the ride. Hence the name “BIG Dude”

A few ground rules were set before the project started. The most important one being the motorcycle had to be comfortable to ride, without making it look like he was riding a kid’s bicycle. This is a problem many riders face, and of the reasons why big guys ride big bikes. And let’s be honest, most café racers, scramblers and trackers look quite petit.

Taller is Better
The modification was made to the rear subframe. It got chopped away, and a new subframe was fabricated with 2 things in mind: it had to be minimalistic, and it had to raise the rear a bit higher. It goes without saying that the complete subframe had to be very strong to deal with the weight of the rider under all conditions. A taller rear shock was added, as well as a taller front suspension, only to increase the overall height of the BMW. One of the benefits of adding the taller front forks, which are upside down, is that they can accommodate for double disc brakes. Not a luxury considering the projects aim.

Modifications
On the subframe sits a new custom-made seat, courtesy of Miller Kustom Upholstery, with built-in taillight, finished in a beautiful brown leather. Moto Adonis has collaborated with MAD Exhausts before, and they have yet again provided the crew with a one-off custom exhaust. A bunch of off-the-shelve gear has been used to enhance the riding experience. A Motogadget m.unit has been adopted to simply electrics. An Acewell speedo provides all the critical info, while we also spotted a set of mo.blaze bar-end indicators on the handlebar together with a set of bar-end mirrors. The original BMW cookie-cutter wheels got a new layer of black glossy paint, and are now wrapped in Continental TKC80 rubber to add function to the form. The matt black color with white stripes brings everything together.

Happy owner
Like all custom-built motorcycles, they are built in the image of its creator. This particular R80 was built with a very specific goal in mind. Its new owner is very pleased with his scrambler, and we can clearly see why. The BMW looks great; the Moto Adonis team can be proud of how this turned out.

Back in 2020, BikeBrewers were invited to join the first edition of the Café Racer Fest in Kyustendil, Bulgaria. Unfortunately COVID had paralyzed the world and travel restrictions caused us to miss out on that event.

We followed the happening on social media while the enthusiasm of participants, visitors and bike builders vibrated through our screens. We knew we missed out on something special! We made a promise there and then, that we would do everything to make it to the 2021 edition. As we are always true to our word, there was no reason not to make the trip this time.

To team members Ron and Adnane it felt nearly as good as going on a road trip even though two flights, three cars but no bikes were involved in getting from Amsterdam to Kyustendil.

Arriving close to midnight, the organizer of the Café Racer Fest and spiritual father of the event, Ivan Mushev of Bull Moto Custom, had kindly arranged transportation from Sofia airport to the ski resort up in the mountains about half an hour up from town up a dark and twisty country road with al sort of wildlife crossing our headlights.

Early start
In order to make the most of the day breakfast was served early and we took off to the centre of town. The empty square would soon be the stage of an extraordinary event, attracting an sizable crowd of both participants and spectators. On the plaza of this nearly 40.000 inhabitant’s rich city, volunteers were busy setting the stage for things to come.

The Café Racer Fest harbours not only custom bikes but also offers a stage for vintage motorcycles and cars from all makes and years. There was quite a collection of incredibly beautiful Pre-Perestroika MZ’s, Jawa’s and Ural sidecars. Truly as if time stood still.

Talking about time, it is funny what the years do with your sense of beauty. Bikes that were considered hideous in the 60’s and 70’s Western Europeans are now considered attractive by the same crowd. Thanks to younger demographics, discovering the fun in riding, Eastern Bloc classic icons such as the 60’s MZ have now grown from being more hideous than the word itself to ultra-cool! We bet there will be quite some young urban riders who would not mind to be spotted on one of those former ‘monstrosities’, were it not that in most large European cities, those two-strokes will never be seen spewing their distinguishable blue exhaust plumes again.

Ride out
Prior to the start of the event, a number of bikers and bike builders met at the local gas station for a ride out to the venue. Little over 150 bikers, nearly of which were modified in one way or another, joined in this brotherly gathering. The atmosphere was incredible; there is something quite special about seeing cafe racers being used for they were built.

Choices, choices
There were three contemporary categories; Modern Classics, Scrambler & Brat, and Café Racers. BikeBrewers were given the task of selecting the Top 3 in the “Café Racer” category. We were given about twenty projects to choose from and had about an hour to finalize our task.

As we always do when judging bikes, we put together a matrix awarding points on a scale of 1-10 for elements such as the ‘Wow!’ factor, originality, quality of work & amp; paint, and craftsmanship and set out separately to do our first independent judging.

You’d expect this to be easy and give clear comparable results. No such thing! We had quite a hefty discussion and with the clock ticking away it required a final walk around to re-evaluate our choices. At the ‘strike of twelve’ we managed to come up with a Top 3 we could both fully subscribe to.

And the winner is…
A 1994 Yamaha XV1100 had scored high points on both our lists and was chosen ‘Best of show’ in this year’s Café Racer category. Its owner, Borislav Alexsov, has put quite a lot of hours in building this machine and is rightfully proud of the result. 2nd place went to Vencislav Angelov with his stunning 1984 Honda CBX 750, and 3rd place went to Kaloian Ivanchev Chekelev with his very cool BMW R75 which saw daylight in 1982.

All top 3 finalists were showered with gifts from local sponsors. To top it off BikeBrewers’ came bearing gifts from our partners Felix Auto Moto and SA1NT! adding a helmet and a sought after twill trucker cap to the basket of each of the category winners!

Come rain come shine
Bulgarians have been spoiled with loads of sunshine over the past couple of months. Unfortunately, rain was predicted during the hours of the event. The start of the award ceremony for the café racer category was launched with a clap of thunder followed by a slight drizzle. That made us feel like home instantly.

Luckily the audience was not scared away that easily, and there was quite a cheer from the several hundred people on the square. According to the organizers, the total attendance during this year’s edition the audience grew with 20% to around 2.500 visitors who meandered amongst all the beauty displayed on the town square this morning.

The next edition
Writing this post just before the party organized by the Cafe Racer Club Bulgaria, we are already spoiled by the kindness of the Bulgarians we met on the way, especially by the members of the café racer community.

As much as we love attending established events in Western European countries, we are always on the lookout for new, exciting and more grass roots experiences. This scene is way bigger and vibrant than you would ever dare to imagine. Everyone we met was proud of the results of their labour and insights are shared freely among this close-knit society.

We will be back for sure and hope the organizers can look forward to an even bigger crowd in 2022. Being the only international visitors this year, we share our experience with the knowledge that this is likely to be the last time we enjoyed this exclusivity.

Given the fact that there is a very lively local scene and magnificent twisty country roads and awesome virgin off road tracks to be travelled freely, it is likely many adventurous bikers from the West will be heading East next year.

We are starting a new item here at BikeBrewers, where we take a closer look at the people that build the motorcycles instead of focusing on 1 specific bike, we call it: Bike Builder Profile. And for the very first edition of Bike Builder Profile, we have a very special candidate from the Netherlands: Moto Rebuild

You may have come across some very good-looking BMW R-series custom motorcycles on the internet or Instagram. The dynamic father-and-son duo, Mari and Maarten Bressers are at the heart of the Netherlands based Moto Rebuild. We’ve asked Maarten a few questions about their business, here’s what he had to say.

BB: How and/or why did you get into motorcycles?
MR: My dad made me addicted, he has been riding motorcycles for 40+ years and has often told me stories about his adventures when he took a road trip. Until one day I wanted to get my driver’s license myself and I always dreamed of building a BMW scrambler. New ones are too expensive, so what do you do when there is an expensive price tag? Build it yourself!

BB: When did you start riding (illegally or legally)?
MR: In 2014 after getting my driver’s license, before that I already owned my first bike, a BMW R1100GS so I couldn’t resist taking it for a spin from time to time… As a matter of fact, my father and I (Maarten) started converting the BMW before I even had my license!

BB: Since the R1100GS, what other motorcycles have you had?
MR: I’ve owned and modified a number of bikes, but mostly Honda’s and BMW boxers:
1981 Honda CB400N, 1980 Honda CX500, 1981 BMW R80RT, 1979 BMW R100RS, 1993 BMW R80R, and 1985 BMW R80RT

BB: Which of those bikes brings back the fondest memories?
MR: I think one of the last 2 motorcycles I’ve owned, both BMW R80’s. That’s because I’ve owned these longer and have ridden them more that any of the other bikes I’ve had. Now that we also ride more often and the summer is approaching, we get to meet more people. The bikes are always an interesting point of discussion with fellow bikers, but it always gives a great sense of satisfaction.

BB: Would you say that you have a brand preference? And why?
MR: Absolutely, BMW Boxers. The reason for that is the way the bike vibrates and shakes when it’s idling. It has a real nice character, very old school.

BB: Do you prefer riding or wrenching?
MR: Both! Our goal has always been to convert motorcycles for ourselves and that we can enjoy them ourselves. If we start feeling that itch to build again, we sell the bike we have, and buy another one to modify. This is the main difference between us and most other custom builders.

BB: What would you like to accomplish as a builder?
MR: I want us to be an inspiration for others, riders, builders and non-bikers. That is why we work on establishing our Instagram presence at the moment. But definitely being an inspiration to others who dream of building their own motorcycle.

BB: With an unlimited budget, what kind of motorcycle would you build?
MR: I think I would continue doing what we are already doing. It’s not about how much money you put into it, it’s about the vision and the number of hours of labor and love you put into it. The aim should always be to showcase the original characteristics of the bike.

BB: One of your latest bike builds is the BMW R80R. Could you tell us a bit more about this bike?
MR: I’ve had the R80R for some time and decided it was ready for a make-over again. I’d lke to think that this model has all the ingredients to create a fantastic custom motorcycle. I had a clear idea of how I wanted the bike to look. Furthermore, it already had wire-spoked wheels, which I absolutely love. It has a mono shock at the rear where we could weld a floating saddle, to give a bit more of a futuristic feel. My inspiration came from the fact that I didn’t wanted an old motorcycle to look and feel old.

BB: Did you face any challenges during the build?
MR: There were a few minor challenges. Coating the wheels took me the most time. I work together with my father on the bikes, we do most of the work together. Besides the electrical work, we do most of the stuff ourself. Some of the notable changes we’ve made are the tank swap, and the front fender. They really finish the bike off.

BB: So, now for the most important question of them all: how does it ride?
MR: It rides like a typical BMW: proper. It handles well, the power delivery and torque are smooth, and it sounds phenomenal.

Two Wheels South
If the name Matias Corea sounds familiar to your ears, it may be because you have heard about his story, or perhaps even read his book “Two Wheels South”. In 2016, Matias travelled 20,000 miles from New York to Ushuaia on his trusty 1983 BMW R80 G/S. This was an emotional journey for Matias, that led to many revelations. We are not going to spoil the contents of his journey yet; a review on Matias’s book will follow soon. However, we are going to have a closer look at Matias’s love for BMW airheads.

Overlander
After traveling 22,000 miles on his stock R80 G/S, Matias came up with the idea to build the ultimate adventure bike for a trip he has been dreaming about for a long time. He considers his Pan-American journey a great learning experience, and knew exactly what worked well on the BMW and what didn’t. Matias wanted to build the ultimate overland machine, based around a BMW airhead, for obvious reasons. He also knew that slapping on a larger fuel tank and a pannier rack weren’t going to cut it. It needed to be perfect.


BMW R80ST
So why not start with the R80 G/S that was already at hand? The answer is simple: the G/S now holds a sentimental value. Modifying it to something else would be too painful. So a different bike was going to be needed. He managed to find a 1985 BMW R80 ST, which in many ways is nearly identical to the R80 G/S he did his trip on. Matias knew the R80 inside and out and felt confident in using it as a base bike. Being a perfectionist, Matias wanted to do as much of the work himself, including the welding, grinding, and electrics. A graphic designer by trade, Matias first started with a couple of sketches and drawings. Once he knew what look he wanted to go for, the project could commence.

Long traveller or long travel?
Building the perfect overlander is not an easy process. Every part of the build needs to be well thought of, and often takes many hours before a final decision is made. First, the R80 ST got stripped to its bare bones. To improve the overall handling, the chassis needed some beefing up. 16 (!) reinforcement plates were welded in 6 different stress points on the frame. To improve front end responsiveness and increase suspension travel, the stock forks were replaced with a set of WP open chamber forks, now delivering a proper 250mm of travel. At the rear, a custom made Wilders shock was added to increase the rear wheel travel by 50%. The rear swing-arm has been extended with 100mm. All of which improves handling and stability at both low and high speeds.

Takasago rims on Talon hubs in the front and rear are held together by heavy-duty stainless-steel spokes. Interesting detail is that the rear wheel has a slight offset, allowing for a wider section rear tire. A Brembo 4-pot front calliper and a 320mm front brake disc give this BMW some modern stopping power.

No replacement for displacement
1001cc. That’s how much volune the boxer engine now measures. The cylinders were bored out to fit high compression 95mm pistons from Moorespeed. The crankshaft, rods, piston, and flywheel assembly were all dynamically balanced together for a smooth and responsive feel. This engine now pulls a healthy 72hp at the rear wheel.
The displacement and flow increase, required larger carbs. Since this is ultimately a touring bike that will have to cruise at both 20 and 80mph, Matias decided to go with classic 40mm Bing units instead of more aggressive options. Bings are consistent, fuel-efficient, and easy to maintain.
To improve the gas flow, the heads were ported, an open air filter were added, and a new Siebenrock exhaust was placed.  The new exhaust system helped get rid of the collector box, and simplified the removal and installation of the whole system on the road. The weight reduction of 11 lbs was an added bonus. With travelling across Africa in mind, Matias thought of a way to deal with poor fuel quality. The ignition was upgraded to a dual curve ignition. This can be switched from the dash to retard the timing and avoid pinging with poor quality fuel.
DAKAR vibe
Looking at the pictures Matias sent us, we can’t help but notice the aesthetics of this BMW. First, there is that magnificent HPN 43 litre (11.3 gallon) nylon fuel tank, which was painted by the same people that paint Walt Siegl’s bikes. A nice detail is a small strip that was left unpainted at the front, to act a as a visual aid to check the fuel level. The rear fender also comes from HPN, but uses stock BMW taillight and indicators. Matias left the dash pretty essential. He wanted it to be easy to read and operate, with gloves on. It’s housed in a HPN Acerbis Cockpit with the stock ST gauges. Matias also added a dual-port marine USB hub, a hazard light switch, and a switch for the second curve on the ignition were added.

More to come…
With the completion of this build, a new era has started for Matias Corea. The responses to this BMW “Myth 001” were overwhelming, leading Matias to start a new company: Myth Motors. Customers can now order their own custom-built BMW “Myth” motorcycle, built to their needs. Something tells us that we will see a lot more from the Myth Motors workshop in the near future!
