My old 98 300 TRX is still going with probably around 30,000 miles on it. The salt ate up the frame so it has a different one; changed the rear wheel bearings once or twice- same with the spark plug. No engine work other than that. Honda is slow to change a formula that works. Unfortunately the changes they've made have been at the expense of their reputation - though I think they've probably overcome many of the issues they had after the engine changes of a few years ago. Mom-in-law has a Rancher almost 3 y-o with nearing 2000 miles; that's not much of a test but her's works just fine. Same can be said for our Grizz of the same age though with 12,000 miles. Models that don't show much change- regardless of maker- are generally the best bet when buying ATVs. That is what Honda built its trike/quad rep on.
