Pffst. Last time we were out, we swapped bikes last half of the day. He wouldn't give me my bike backNice YZ! you need to ride it once. You'll sell that RM a day later.
Honestly though, his bike is a little more peppy on the bottom end over my bike but my bike is on its 4th year on the piston and his is a fresh rebuild so that might be why my bike handles 10 times better though and I'll take handling over a few HP any day of the week.
