07 Yamaha yz450, also purchesed a 07 TT-125le for the wife and a left over 05 pw80 for my son. No racing here just going to trail ride. Last dirt bike I owned was 96 CR250. I will probly leave the bike stcok seems to run very well. Lots of low end good mid and very srong top. To me anyway. Starting seems to be the bigest issue to get used to.
