BMW customs seem to be far more common in Europe than the US and this one by CAS Racing, located in Spain, is one more example. Starting out as a BMW 1150RS, the Paralever rear, standard issue on the BMW, is all they needed out back. A subframe mounted to the engine holds the bodywork which was shaped by first carving a foam mold. Up front is a more substantial subframe used to mount their single sided front suspension.
CAS Racing modified the engine with 14:1 compression and a modified blackbox with custom ignition curves. The added their own airboxes and exhaust. Handlebars are from a mountain bike which gives it a compact and clean look.
An interesting addition is the biometric ignition. A small scanner on the tank reads the owner's thumbprint to turn things on.
Why don't we see more BMW customs over here? They seem to offer a lot of room for innovative ideas and they certainly haven't been overdone like some bikes. Hmm ...
