Yamaha introduces TY-E electric trial bike

Yamaha Motor has developed the TY-E electric trial bike—taking advantage of the unique features of electrical power—and has been working toward competing for the first time in the 2018 FIM Trial-E Cup with scheduled appearances at the Auron in France from 14-15 July, and the Comblain au Pont in Belgium, the following week.

Kenichi Kuroyama, who is currently competing in the IA Super class of the All Japan Trial Championship, will represent the Yamaha Factory Racing Team. The TY-E was also on display at the Yamaha Motor booth in this year’s Tokyo Motorcycle Show, being held at the Tokyo Big Sight last month.

The TY-E features include a CFRP monocoque frame that offers the lightest possible weight, while ensuring optimal rigidity and battery storage space. Unique shaping is created by the gradation of surface expressions towards softness from the hardness from the wheel to the rear fender. The slim body is formed by a distinctive polygon shape that is made up of lines drawn tightly, but without conflicting around the internal structure.

Other characteristics include a high rotation type compact high-power motor that is said to achieve high off-road performance with both powerful low speed torque and extended acceleration, motor control technology, a power unit equipped with a mechanical clutch that secures instantaneous power and control, an electric motor and optimised flywheel that realises excellent traction performance, and high-output of a newly designed compact high-output battery pack with compact and lightweight components.

The TY-E is an advanced development deriving from the company’s Evolving R&D activities. The Evolving R&D uses 5% of its working hours at the Research and Development Division, and at the discretion of its staff, is used as an opportunity to provide voluntary and autonomous activities for creating innovation while not being bound by conventional frameworks.

“It is here that we focused on a trial model for competition and worked on its development to help overcome EV development problems such as high output from small sized and lightweight components, and the ease of riding that responds as the rider would intend,” the company explains.
