Yamaha is trialling a unique power steering system for its award-winning motocross range. The prototype support system provides steering benefits at high and low speeds.
While technological developments in motocross bikes are usually adopted slowly from road bike innovation, the unique electric power steering (EPS) feature would be the first of its kind for the motorcycle industry.
The system uses a torque sensor, magnet technology, and an actuator that results in steering damper benefits at high speed and steering assist input at low speed. It has already be utilised in the brand's electric-assist bicycles.

In theory the EPS system would provide riders with improved stability and help reduce fatigue at high speeds and in rough conditions. It would also provide steering assistance that contributes to improved lightness and agility at low speeds.
Australian motocross star Jay Wilson has already tested the system with the All Japan Yamaha Factory Racing Team. The team will use the system in this year’s All Japan Motocross Championship.
Yamaha plans to expand more into the area of electronic assistance, and it hopes to equip various motorcycles in its range with the EPS system. Further details and a timeframe of fitment to future production models is yet to be revealed.
