I had a DRZ400E. Am weekend adventurer. Rode everything from street to extreme rock garden crawler uphills. Bought a KTM 450EXC.......... never looked back. Maintenance hasn't been an issue. If you ride like I do, you're always maintaining them anyways. Change oil more frequently...... so what, takes 10 minutes. Valve checks..... I rail the shit out of the bike and have only adjusted them once in 150?? hours LOVE the bike . . . . . 6 speed is nice too.... cruise at 60mph at 1/4 throttle?
