Well after actually riding it in the dirt it's not exactly twice as powerful. The XR600 actually has more at the very bottom. It can chug up something really steep in second and the beta needed downshifting in places where the XR didn't. Now that might be partially due to the gearing, as the dual sport version it comes with 15/45 gearing that's great for the freeway, but not so much for the trails. One of the holdups earlier this week as that the bike had the wrong front sprocket on it. Not sure what was up with it, but the chain didn't mesh on more than two or three teeth. Must have been a 525 chain size sprocket or something. I had them put a 14 on it. I'll be going with a 48 or 50 rear for sure.
Now one the revs get higher, the situation changes. There is a lot of go in that engine. I did give is a few seconds of full throttle at low to mid rpms. All I can say is Wow, and you had better have a good grip on the bars.
Other than wide open desert I just don't see where I'd ever do lots of wide open throttle. Most of my riding will be a low throttle openings. Not exactly a lot of opportunity for wide open on trails.
Well I now have 3.1 hours on the bike so I can do that first oil change.
