Today riding home from work I decided to test the max speed on this bike so I put it in 6 gear and grabbed a handful of throttle. I hit 8000 rpms and was at 110 mph, and the bike had more to go but I backed off the throttle because I was getting serious front wheel shakes. I haven't checked the tire pressure since I got it from dealer, but know that the tires are hard as rocks! Could this be causing the front wheel wobbles/shakes at high speeds? I took some air out the front and rear tire but have not checked the exact tire psi. I will be a tire pressure checker tomorrow to set the tires up correctly.
