Bridgestone Battlax BT-46 Front Motorcycle Tire 100/90-18 56V

The Bridgestone Battlax BT-46 Front Motorcycle Tire 100/90-18 56V is a bias-ply tire made in Japan and built for vintage sport and touring motorcycles. Bridgestone designed it to handle a range of conditions, from city streets and long touring miles to twisting roads, and they cite improved wet performance as part of what the BT-46 brings to those situations.

The size code 100/90-18 tells you the section width is 100 mm, the sidewall height is 90 percent of that width, and the rim diameter is 18 inches. That rim diameter must match your wheel, and the full size code should match what is printed on the sidewall of the tire you are replacing. The load index of 56 and speed rating V, which covers speeds up to 149 mph (240 km/h), are both required to meet or exceed what your machine calls for, so check your owner's manual or the placard for those specifications before ordering.
