The YZ450FX is tuned well for these types of conditions. It has a fantastic amount of torque, good bottom-end, strong midrange, and can rev plenty far for single-track riding. The biggest challenge is making the power work best for the conditions. I never used first gear on the course layout we rode in South Carolina. Second gear was good, but if you were not careful, the bike could easily get away from you coming out of corners. If the trail was open, you could almost carry third gear with only a little clutch input. A few of the lighter test riders reported they had absolutely no problem running third gear throughout the single-track. To help control the hard acceleration of second gear, I tried using the optional preprogrammed map 2, which is slightly more mellow, and I found second gear to be more controllable but felt it could still be improved on. So we headed back to the truck to get the 411 on the Yamaha Power Tuner app and how it could help.
