For a bike that's about as old as the man who's put it together, this BMW RS09 looks pretty damn good! And we're sure that Termignoni can sounds awesome...
Roel Scheffers, 28 years old and a resident of Tilburg, in The Netherlands, is a CAD/CAE engineer who has a passion for building his own bikes. And going by the 1985 BMW K100RS you see here, he’s not too bad at it either. ‘I bought this ’85 BMW K100RS for 500 euro. It wasn't running – the starter was broken – but with a little push, it ran great and that’s after spending five years standing in a shed. I wanted to do something new, I wanted to do something with a bike that isn’t really known for its potential for customization,’ says Roel. ‘My dad had a K100RS like this when I was young and we did a lot of touring on that one, with me on the back holding on with all my might! So I've always had a feel for the K100RS since I was little. I think there were around 70,000km on this one when I bought it, and it was very well preserved. My dad told me to fix the minor fairing damage and earn some money by selling it. I told him I was going to chop it up,’ he laughs.
Roel has spent a considerable amount of time and money towards modifying his ’85 K100RS (which he’s named RS09, since it’s his 9th custom build), adding bigger injectors to the 1000cc engine, a homemade stainless-steel intake-plenum, K&N filter, adjustable injection pressure valve, and homemade stainless steel exhaust with Termignoni silencer, a self-made sub-frame and K1100 ‘sports’ rear shocks from Koni. He’s used thicker oil on the standard BMW front forks, and lowered ride height at the front by 4cm by moving the forks up through the triple yoke. Both front and rear fenders have been removed, the stock aluminium fuel tank has been modified and made narrower (fuel tank capacity is still 20-litres, so not bad at all…), the front fairing has been modified, the seat has been shortened, and a Danmoto digital dashboard and new aluminium clip-on handlebars have replaced the original items. The light pearl-white paintjob with candy-blue striping was done by Kustombart and Roel estimates the cost for putting the whole bike together was about 3,000 euro.
‘The most difficult part of this build was the TIG-welding. The stainless steel exhaust is completely TIG-welded and it was actually my first TIG-welding project. The BMW aluminium gas tank is modified and also needed to be TIG-welded. The seat and front fairing are formed with help of polyester, something I hadn't done before, so I learned a lot during this project! I did everything myself, except for the paintwork,’ says Roel. Next up, he says, is fine-tuning the engine on the Dyno, which should get about 100bhp and then ride the bike on some big trips next summer. ‘Now that the bike is done, I really enjoy riding it. It handles great, has good power and turns a lot of heads! Even people who're not into bikes seem to appreciate it,’ he says.
Well, we also like this BMW RS09 and we hope Roel will continue to build more bikes in the future. Take a look at his website for more of his work.
