I have a 2006 YZ450F that I purchased new from the dealer. It was left over in the warehouse, so the price was right. Returning to the dealer now is not an option. Since purchased in Feb 2011, I put 6 hrs on it. The front brake rotor is rubbing against the side of the caliper. The rotor is not bent as it is not rubbing at different points in the wheel rotation, its a constant rub.. When the bike is on the stand, I cannot get a complete revolution out of the wheel when trying to free spin it. I've never removed the front wheel, brakes, or adjusted the forks. My guess is that either the front spacers were mixed up at the factory, or the brake pads were installed incorrectly. The front wheel does seem to be a little offset towards the right which correlates with the rotor drag on the right side of the caliper. Any ideas guys??
