20 mile commute each way guys? are you serious about this thing not staying together? don't listen to these guys...wr/yz is WAY rock solid and requires little more than oil changes/air filters. I've had mine for almost a year now, daily commuting and oil changes like every 1500 miles (oil still golden, btw) and both times i checked the valves they hadn't budged. Maintenance stuff gets SO blown out of proportion its stupid. The drz is a great bike, no question, but i'll deal with oil changes twice as often for roughly 20 more hp and 50 lbs less weight.
