The TW has a longer output shaft, an outter support bearing and a dogleg in the left side of the frame for chain clearance. Swapping the rear tire into something else is in the major project category..
If you truly want a low speed trail bike the TW delivers in spades. More conventional dualsports need to be ridden faster over the same terrain, but have the edge in terms of suspension travel and high speed handling.
You pays yer munny and makes yer choices.
