OK so I pulled the handle--2010 WRR. I got it to replace my CRF230L which had 8,000 on it in a year. This link will give you an idea of my riding.

The WRR will replace both the 230L and my XT350. I'm mostly offroad--riding on road only to get to the offroad!
I normally get in 15,000 or so year on my dirt bikes, with most riding being above 6000 feet. I'm a bit concerned with the size of the tank on the WRR and I really don't want to add an IMS or similar. I'll be checking in and lurking.
