I just put a deposit on a 02 520MXC. Choose the MXC since it has a happy button, and 6 gears. Plan to use the bike for mostly general trail riding and a few vet class MX races. I would like to solicit feedback from other RFS owners as to the anticipated reliability, performance, and undocumented maintenance procedures that should be observed. I have previosly owned and rode mostly 2 stokes (97 Honda CR 125 and 89 CR 500 both gone) and ride/race vintage mx bikes. Thanks in advance for your feedback.
