May be a dead topic, but couldn't find much by searching on it. Have a 1996 Timberwolf, that is in mint condition minus the rear end, ring and pinion are destroyed. Anyone know if there is any models that I can swap the whole swing arm assembly that will bolt in?

 

Yamaha list three 250 models for 96 I guess the others will share the rear axle. The earlier 250 Moto 4 doesn't, nor do the later 250s. Your model wheel and pinion costs a lot more than either the earlier or later one, hard luck.
