XR 600 or XR 650r Which bike do you guys think is the best buy for price versus power? I have a xr 400 right now and looking at the bigger thumpers for my next bike. I have seen xr 600's in good condition for as low as 1500-1700 and it seems that the xr650's run around 3000 for a good one. Is the extra hp worth the extra money with a 650r? And does the 650R "with it's bigger cam" have the low end torque of the xr 600 ? I mostly ride dirt roads and 2 tracks on state and federal land, not many tight trails.
