Tire Size Calculator

[wilcom]

Been looking for a tire calc that would do motorcycle sized tires. The Miata site had a good one for car sizes but wouldn't do bikes. The calculator here at the Tacoma site will accomodate our sizes.

I just changed the rear from a 120/90 to a 110/90 and it felt like it was accelerating quicker. Sure enough, the change lowered my gearing by 3%, enough to feel in high gear roll-0ns
