Yamaha Motor Co., Ltd. has developed the TY-E electric trial bike – taking advantage of the unique features of electrical power – and has competed in the 2018 FIM Trial-E Cup with appearances at the Auron in France through July 14-15, and the Comblain au Pont in Belgium through July 21-22 last year.
In participation of the competition, Kenichi Kuroyama – who competes in the IA Super class of the All Japan Trial Championship – represents the Yamaha Factory Racing Team. The TY-E was also on display at the Yamaha Motor booth at last year’s Tokyo Motorcycle Show, held at the Tokyo Big Sight.
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.
TY-E features include a high rotation type compact high-power motor that achieves high off-road performance with both powerful low speed torque and extended acceleration; motor control technology that achieves an excellent response and a power feeling from extremely low to high speed ranges; a power unit equipped with a mechanical clutch that secures instantaneous power and control, and an electric motor and optimized flywheel that realizes excellent traction performance; high-output of a newly designed compact high-output battery pack with compact and lightweight components; a CFRP mono-coque frame that is at the lightest possible weight, while securing optimal rigidity and battery storage space, and; extreme slim styling that does not interfere with dynamic rider action.
This is the only FIM (Fédération Internationale de Motocyclisme)-sanctioned event where electric trial machines alone can compete. This event was held for the first-time in 2017 on June 24-25 at Lourdes in France. Here, 11 riders entered, with Spain’s Marc Colomer winning. In 2018, two races were scheduled; Auron in France July 14-15, and the Comblain au Pont in Belgium July 21-22.
