New Moto Guzzi Door Mats Available Now
I knew a fellow who endo-ed a moped because the front fender came loose and went into the spokes. He said it began with a tinging noise as the brace began skipping off the spokes - he said to himself " What the - ? " and never got as far as the expletive before the machine flipped and his shoulder was separated in the impact with the road.
On the way home from my first service I almost lost my Roamer front mudguard (fender) due to the screws rattling loose. I heard a rattle so pulled over and found one screw only holding it. Might pay to check your screws for tightness and maybe do what I did and Loctite the four new ones in place. Assume the Bobber would be the same.
