It seems I may finally be forced to ditch my beloved SE. About the RC8, what would it take to get some more force than the 150 hp? Why not put the RC8 unchanged into the new 1290R? To be compared with my SE with the SD 990R motor, soo much more fun to ride than the oem 950, (yes, on gravel too, at high speed) I like the tighter gearing as well. About the 21/18 versus 19/17 rims, I'll buy both on day 1.
