I guess we'll see how it looks when I go to re-ring.

At 2.5 hour intervals my son's bike which just rolled 64 hours this weekend would have seen 25 oil changes at 2.5 hours per, or 16 at 4 hours per. So let's round off to 10 extra oil changes in a season and a half that's about $35 total for the peace of mind.

Even good maintenance can't overcome a poor design or manufacturing. |

From 04-06 I would never consider anyone buying one. We have an 07 and it had significant clutch issues that can be resolved with a few parts that Suzuki added to the 08 clutch. For 08 the issues appears to be resolved. Based on watching internet chatter I would suggest the 07 and 08 RMZ250 has as few or less issues than any other brand 250F out there. |
