I'll print it off and put it in my bike tool kit. Then next time I'm sitting by the side of the road waiting for the recovery service to arrive I can workout exactly what the F*** went wrong. ;) Nice find though

So, the fact that Buell belts normally snap means either:

Quote:
Shockloading is the transient application of loads significantly beyond design load. The belt teeth in contact with the sprocket at the time of the shock load will usually show root radius damage with possible tooth shear. The broken tensile member will exhibit a ragged, uneven appearance across the break. The remainder of the belt may appear in new condition.


or

Quote:
The introduction of debris between the sprocket and belt effectively increases the center distance beyond the design limit of the belt resulting in rupture of the tensile members.


Maybe the belt just isn't up to the job - the belt on an 1125R is nearly 1/2 the width of the belt on a BMW F800...
