I just bought a '00 WR400F comes with motard-wheelset, since I wanted to try Supermoto.. I prefer ride dirt, so I would like to get another set of dirt-wheelset as a plug & play set whenever I want to ride dirt. So I'm keeping the current motard-wheelset as it is. Hope can get help from the expert/experience Yamaha riders here. To buy a new set cost a bomb! Got offers on a used set but for different models. Sorry for these stupid questions:bonk: , I'm new to this WR400F. Q1) Can a 1998 WR400F front & rear wheelset/hubs fit into a 2000 WR400F? Q2) Which year YZ front & rear wheelset/hubs can fit into a 2000 WR400F? Q3) Can a 2007 YZ250F front & rear wheelset/hubs fit into a 2000 WR400F? Q4) Are the 2000 WR400F swingarm different from a 1998 WR400F? Q5) Whats so different on the 2000 WR400F hubs than the rest? Q6) What other bike make/model hubs can fit to a 2000 WR400F? Q7) My friend is selling KTM400 ('00-'02 model) complete front & rear wheelset good condition with great tyres at a damn cheap price, if I buy can it be simply modified to fit my bike? Thank you in advance for the useful advice.
