BMW R1100R vs XS1100

(one of them also had a Sunbeam sidevalve in olive green).

Hi James,
that would be the S7?

For all it's many faults that bike had a SOHC engine.
FWIW, I reckon if they'd doubled up that engine into a 1,000cc 90º V4, used a BMW rear drive instead of that self-destructing worm drive and done something sensible to improve the brakes that bike would have really been something.
