My XR650R in Supermoto form has no cush drive....but as you say the Ten is designed with one. Talon do a hub with cush drive. I've thought about doing this....was thinking about a 19 inch front in order to get a bit more rubber down up front. As the rear is already a 17 how about lacing a wider rim onto the Tenere hub...you could then fit the widest tyre, (swing arm permitting ), that would solve the cush drive problem ...not being very helpful I'm afraid, just throwing some ideas in . Initially I missed that planted front end of the XR , but as confidence increased I find myself getting braver on the Tenere . I'm selfishly hoping you do this as I would love to see what the Tenere looks and handles like in SMOTO form!. Steve
