My friend and I both bought 650's last September. I have 3,000 miles on mine and he has over 11,000. He rides a great deal and said his scooter felt like it had a flat tire. After checking the front wheel bearings, which were in bad shape, he removed the rear wheel and the bearings were SHOT. Both appeared to be dry from day one. Dealer wanted $17 per bearing, local machine shop supply asked $4 each and they were identical. With the wheels off of the ground, you could move the wheels side to side. Anyone else having any trouble. Both scoots were mfg. in 3/03.
