This bike is IMHO the best looking BMW ever! It's the team Incomplete BMW, it started as a R90S and ended up as a really purposefull cafe racer.
It's using an old engine with much work done to improve it including twin spark plugs, a special frame based on a later model, modern brakes etc.
The result is a bike good enough for track days, while still keeping the classic spirit!
I'd like to see what others consider as really special bikes!
