Never seen them side by side but when they first introduced the roadster, it supposedly had an upgraded drive train to deal with the "huge" increase in power (yawn).
indeed however I do not see any heat damages the u-joint are silky smooth the rest is all metal if somebody buys it I will inform them of the slow cooking
hey duke I guess that wont fit my bike, but what are the differences,seems the splines would stay the same or the diff would be different. the parts listing said one part # would fit 2006 to 2017,but the roadster part # would not fit a 2005 doesn't seem right, and theres a price difference.
