Lightweight, High-Rigidity Aluminum Wheels for Motorcycles

A solution combining high-precision casting and flow forming

Lightweight, High-Rigidity Aluminum Wheels for Motorcycles
  • Lighter weight
  • Higher rigidity
  • Greater toughness

The wheels of a motorcycle are critical factors in determining its handling performance. The lighter the wheels are, the greater the handling stability and overall performance. However, at the same time they need a high level of rigidity to withstand the forces they are subjected to as well as the toughness for lasting durability. Achieving these qualities would not only require a carefully selected aluminum alloy but also combining high-precision casting with flow forming methods. Yamaha boasts a stock of advanced casting technologies and techniques acquired through long years of casting parts such as motorcycle wheels and frames. These were put to use to successfully develop new aluminum wheels that are lightweight, strong, and have the right amount of flex.


Manufacture lightweight, high-rigidity aluminum wheels for motorcycles
