Hes going to pay for it. But we are seeing if Yamaha will cover it under warrinty. He was just going about 15 -20 MPH and hit a curb and it bent bad right where the axel attaches to the wheel. The wheel is fine you can see a mark on the tire where the curb hit it. He wasent doing anything crazy or sliding just riding over a curb is dosent seem like it should have bent like that.
