I have a 2012 Goldwing with a motor trike kit. I started noticing a knocking coming from the front area and think its coming from the front tire.3k miles ago i put a rear motorcyle tire on the front like so many recommended.Would that cause the bearings to go out in the front tire? I normally hear it when taking off slow.Sound like a bearing going or gone and if so what can i expect in cost at a shop?
