Im assuming that the belt is a oem. It was installed by the dealer. I bought this bike from the dealer as a used bike with 5600 miles on it. The tires were worn out and the belt was squealing at engagement. He agreed to replace both tires and the belt. I rode a Reflex for 27,000 miles a few years ago and these milages seem to be horrible. On the Honda I averaged 7,000 miles out of the rear tires and 12,000 miles out of the front. I also went almost 20,000 miles on the oem belt. I admit it was toasted when I changed it, though.Why is this bike using up consumables so much faster? Curt
