Just got home from the first ride on the bike in the mountains. Power is controllable, kind of like my 520 EXC & 525 EXC were only more! It's geared way higher, 15-40, I may gear it down some. It starts perfect off the e starter, hot or cold. I did find when getting the bike home it kicked hard but thought that would be normal for a 650. Checked the valves, the exhaust was a little loose, adjusted them. Now it kicks easy, they were loose enough the decomp wasn't working. The bike handles great, when on the power like winding uphill thru trees it is very stable. Doesn't blow the tire like some "hot" bikes will. Love that 4 stroke power! :twisted: I didn't really notice the vibration, we rode about 87 miles yesterday & I wasn't beat from it.
