Been running a 99 800 XCR / M-10 this season. Couldn't agree with Polar800 any more. It's not something I would want for MX style action, but when it comes to trail or lake work the only word to describe it is awesome. Maybe it's a couple pounds heavier (what maybe 10 or 15?) than the GenII but so what? Maybe thats whats getting me through the chatter bumps so well. Go with what you can get a deal on, don't be scared of the aggressive chassis.
