MT75 tires are more sticky though, so i'd assume more rolling resistance. Those stock dunflops are harder than rocks, so less, i'm assuming you're rocking the stock flops?
Yes, on the first post i explained that the only modifications to my bike are a 15T front sprocket, 39tooth rear sprocket, and Kenda Tires (touring tires) that are slightly taller than the stock dunlops.
