ok guys, i picked up a 2002 TTR125 from a buddy and i am trying to find a good place to find upgraded parts. I am a big guy (6ft5inover 200lbs) and am trying to make this a pit bike. I cant already tell that the rear shock is trashed. I would usually just buy the OEM replacement but being that big dude+ tiny bike= suspension issues, i am looking for a good upgrade. Everything i have found doesnt look like it would work with the way it mounts to the bike. Im new to bikes so help me out!!
