I just got a 07yz 450. It has good cages and ASV levers,and Maxxis desert IT tires This is going to be my part time desert bike. I already have a 08wr450 with revalve, respring, levers,cages,tires, stabilizer, ect.. I would like to make the yz as desert friendly as possible, but still take it to the track like it was made to do. I rode it for the first time in the desert Sunday and I had a blast. Would a gearing change help?
