Yep.

I'm curious because the Race Tech recommendation for replacement springs for the TRX is a 35mm by 340 mm, the mk2 TDM 850 is 37mm by 320mm and the mk1 TDM 850 is 32mm by 340mm :? ...yet they're all 41mm forks. :shock:

The one that makes sense is the TDM 900 at 38mm by 370mm as it has 43mm stanchions
