Luckily for us, the standard is pretty high when it comes to their custom built motorcycles, and the BMW you see here today is no exception. Built on behalf of Bartek Prokopowicz, a Polish movie director and lifelong petrolhead, Grzegorz Korczak decided to do something different this time. What started out as a standard BMW R80 police style motorcycle, has been transformed into a cafe racer styled tracker. What makes this 1978 BMW even more special is the treatment all surface areas were given to get a very distinct look. Take a closer look and you’ll see what we mean. Some parts look a bit rusty, and maybe even a bit rough and dirty. Make no mistake, this was done on purpose, through a series of rigorous processes, to achieve this unique, patina look. As if this BMW was built a long time ago. Very cheeky!

It’s clear that this BMW R80 is meant to look a bit rough and used, but that’s just one part of the story. Underneath the surface, everything was redesigned. Let’s start with the most notable changes, like the rear subframe. Or rather, the lack thereof. We see that on top of the minimalistic subframe a beautifully stitches single seat is resting. It almost looks as if it is floating. Some of the worlds’ smallest LED brake and indicator lights can be found underneath the seat.

To keep a clean look, the battery had to be relocated somewhere less obvious; underneath the bike. A custom battery bracket was fabricated to allow for the relocation. This gives the BMW a clean look. The engine and air intake has been kept stock for a change, and we love that! Everything was done to ensure the 800cc boxer is up to snuff, thanks to a thorough inspection and service. At the front the suspension was upgraded to YSS springs and received a pair of fork gaiters. A set of YSS fully adjustable twin shocks take care of business at the rear.

But there is more! Although the rest of the front looks stock, most isn’t. First there is the Motogadget speedo, that looks a lot smaller than the factory cockpit. A black aluminium handlebar replaced the stock steel unit. The handlebar grips have been wrapped with leather, and at the end of them, a pair of Motogadget bar-end indicators have been mounted. A classic oversize black round headlight adds to the distinguished look. The custom short fenders, the blacked out exhaust headers, and the twin brushed end cans all add to the classiness of this R80. No wonder it took almost a year to complete this project!

In the end, UNIKAT managed to create yet another timeless looking custom motorcycle. It’s hard to imagine that they built another bike simultaneous to this project. And yet, they did just that! Stay tuned for more, here on BikeBrewers.

This time Grzegorz Korczak, the man behind Unikat, got his hands on a 2021 Triumph Bonneville Bobber. I know, I know, this looks like a different kind of bobber. Truth be told, there are different definitions of what makes a bobber, a bobber. There are European and American style bobber, there are also Japanese style bobbers. Regardless of the different styling exercises, one thing that they all have in common is the fact that they appear to be minimalistic. In a way, you could look at this like this: what a café racer is to a road bike, a bobber is to a cruiser. Same rules apply: get rid of all unnecessary parts to reduce the weight, and make the bike look as simple as possible.

Coming back to Unikat’s Triumph Bonneville Bobber, which has been name “K18”, we see that a number of stylish mods have been made to the original. No doubt did the original Bobber look great, but what Unikat did here takes the stock bike to a whole other level.

The original bobber wheels have been replaced with a pair of lightweight, black Takasago Excel 17” rims with stainless steel spokes. What’s interesting about the wheels is that they have adopted the BARTubeless system; transforming them into tubeless wheels. The rims have been wrapped by a pair of sticky Pirelli Dunlop Mutant tires.

The rear fender had been completely removed, while the front fender got a nice trim job and received a distinguished Unikat 1-of1 logo, kind of like an easter-egg, waiting to be discovered. Staying at the front, we can also see that the speedo and the headlamp have both been lowered for a sportier stance. There’s a set of Motogadget bar-end indicators, which have been combined with a set of bar-end mirrors. The handlebar grips have received a nice leather wrap treatment. Womet Tech supplied the sporty clutch and brake levers. A pair of fork gaiters keep the front fork clean and mean.

Moving a bit more backwards to the fuel tank, we spot a beautifully milled, gold anodized fuel filler cap. Underneath the fuel tank, the original factory airbox has been removed and a pair of free flow air filet, curtousy of K&N have been placed to take care of the breathing. The ‘faux-carburetor’ injection covers have been treated to the 1-of-1 logo treatment too. Underneath the engine, a stainless-steel exhaust system, in combination with Unikat’s very own in-house built exhaust pipes, ensure that the combustion gases leave the engine in an effective and dramatic manner.

A lot of work has been put in cleaning up this bike by hiding as much of the wiring as possible. Part of that is the Hi-sider 3-in-1 taillight, that have built in indicators and license plate holder, and is in fact completely road-legal. The special thing about is, is that it is integrated into the single-seat. The finish of this Triumph in a gorgeous dark green color in combination with glossy black, with all the little gold-colored details really distinguishes this build from any other Bobber we have seen so far.

Polish Perfection

Not an XT500
The motorcycle we are seeing in front of us is NOT a Yamaha XT500. We know, if it walks like a duck and talks like a duck… The little surprise we have here is in fact a Yamaha SR500. Technically related to the XT500, but designed with a completely different purpose. This unit is from 1982 and would be perfect for what the owner had in mind. At least, that was until he changed his mind and pulled the plug on the project. The SR500 got cold-stacked and spent 2 years in a storage before another customer decided to take over the project and commissioned the build to continue.

Legendary
In the past 5 years we have only covered a couple of builds that are based on a Yamaha XT. It is one of Yamaha’s biggest success stories and a legend. Yamaha introduced the first XT, the XT500, in 1976 with a 500cc single cylinder air-cooled engine. It was known for its tractor-like torque and power delivery. The XT also had a reputation of being absolutely bulletproof. Production halted in 1989 when the XT600 took over.

Rebuild
So how do you change an SR500 into an XT500? The answer is far simpler than you’d think. Most of the XT500 looks where achieved by cleaning up the SR frame and by adding an original XT500 fuel tank. The custom seat played a major role in achieving the desired look. To make it all work, the necessary mounting points had to be fabricated as well as adjusting the subframe to make the seat pan fit.

An original XT500 triple clamp was sourced to allow for taller suspension at the front. Original XT500 wheel and forks with progressive springs added flavor to this build. The rear wheel is an original SR500 unit, but the rear shocks aren’t. A set of fully adjustable YSS shocks which are longer than the original shocks help increase the ground clearance. While the rear end was being reworked, a chain tensioner was added to the rear swingarm.

Vintage
The bodywork was completed with a vintage replica of an ufo enduro headlight, an original XT500 front fender, and a customised rear fender fitted with a TT500 replica tail light. In the rear they attached the famous Supertrapp 3″ series dirt bike exhaust and set it up to work with the carb. To create a real vintage look, the builders looked closely to some of the original Yamaha XT color schemes, and then decided to go with the famous 1980 XT500g monochromatic white/black/brushed metal look.

Performance work
To improve the XT’s reliability and performance, the engine was rebuilt, and the carburettor was equipped with a new set of jets. The airbox was replaced with a K&N pod filter. The wiring loom was modified to keep all the cables nearly invisible. There is no battery anymore, just a condenser. It goes without saying that the SR-turned-XT is light. Very light! It is also nimble, and has a strong pull. According to Christian, the exhaust sounds pleasing to the ear in the low and mid revs and is not too loud in high revs. It is quite easy to start, once you get the idea on how to do it correctly. Its torquey engine and comfortable riding position makes it a functional enduro bike for light trails and occasional rides. This project took about 1 year to complete.
