The Bridgestone RS12 Rear Motorcycle Tire 180/55ZR17 73W is a radial rear tire built in Japan and aimed at riders who want grip that holds up over repeated hard laps rather than fading as the session goes on. Bridgestone redesigned the tread pattern specifically to raise tire rigidity and increase contact area through corners, which is how they say the tire keeps its grip consistent across a range of riding conditions.
The size code 180/55ZR17 tells you the tire's section width is 180 mm, the sidewall height is 55 percent of that width, and the tire mounts on a 17-inch rim. That rim diameter must match your wheel, and the full size code should match what is molded into the sidewall of the tire you are replacing. This tire carries a load index of 73 and a speed rating of W, which covers speeds up to 168 mph (270 km/h). Your machine's specification sheet tells you which load index and speed rating are required.
