“18”: The Wheel Diameter - The Benchmark for Classic Balance and Performance

The 18 inch wheel has been a standard across a large portion of motorcycles for decades and there is a wheel engineering reason for this. The stability and agility is remarkably balanced.

The most optimal balance is an 18 inch wheel which is a balance of a 17 inch sports bike wheel which ultra nimble and 19 inch wheel which is enhanced stability and obstacle rollover capability. This balance is why it has been a preferred choice for standard motorcycles designed for city commuting, back road riding, and highway travel.

This tire will also be a highly effective shock absorber. It will not only smooth the terrain, but also the ride, and as such, better the level of comfort for the rider even more so when the ride is longer.
