1983 BMW R100RS
Featuring 70hp as standard, the R100RS was always a performance oriented machine, what we've done is an attempt at injecting some of the classic 70s design that was lost as the airheads evolved through the 1980s.

We describe this build process as a nut and bolt restoration to our own design.  The bike was completely torn down and rebuilt as new. The frame is powder coated flat black, the magnesium rims are powder coated flat black. The headlight bucket is color-coded and the handlebars feature a brand new Motoscope Tiny speedometer from Motogadget.

The gas tank is painted in a color called Fashion Grey, a color from the Porsche palette of the 1950s, most commonly found on the 356 and later used on modern cars such as the 997 Sport Classic.

The 1000cc engine is a fresh rebuild to factory specs, featuring high compression machined heads with new valves, honed cylinders, and new piston rings.

The carburetors are brand new Mikuni slide carbs, jetted and tuned to suit the reverse cone exhaust setup. They offer a crisp throttle response and increased performance.

The bike is fitted with an all-new electrical system, featuring a brand new factory wiring harness, upgraded ignition system and an upgraded charge system featuring a solid state alternator.  The factory charge system was always the weakest link and these revised modern components eliminate that weakness completely. 

Bar end turn signals from Motogadget compliment the modern electrical upgrades, manufactured to German TUV compliance, their manufacturing quality exceeds OEM standards and the visibility they offer is excellent.  An led tail light and handlebar mounted mirror complete the road legal compliance.


The powder coated rims are fitted with new tires and heavy duty inner tubes.
