In Thailand we have 2 bikes (2009),one is the D-Tracker(road bike) and the dual purpose bike. DTracker is a little lower, but has 17inch wheels.
The fork springs have different part numbers.
(44026-0109, 44026-0103)
What's the difference? Length or spring rate?

Models T9F and W9F.

 

Spring rate.... sumo bikes have stiffer springs.

 

also the fork tubes have different part numbers, so I was wondering what difference it would make if I swapped the springs

 

I think the sumos have less travel as well.
