Got a question my lt150 ride rougher than my 50cc. It is only the front that is choppy. The front tire is smaller than the back. The tires are pirelli and have 1800 miles on them not worn. What canbe causing this? Sorry about my limited knowledge on all things with tires. Could it be the shocks. Thanks for the help.Front tire 80/80 16" back110/80 14'.
