Yamaha Begins Upgrading ECUs On New Motorcycles — Will It Make The BS-VI Engine Better?

Reports are that the upcoming Yamaha MT-25 will feature a more advanced ECU than the R3. The ECU (engine control unit) basically controls all the electronic functions of a motorcycle. The ECU also helps in determining the best fuel and air mixtures, depending on how one opens the throttle.

While the report does not mention how the upgraded ECU will help improve performance values of the motorcycle, we think it will definitely help extract more power from the existing 250cc twin-cylinder engine.

There are rumors that Yamaha might also introduce the Variable Valve Actuation (VVA) technology to help the new ECU perform better. The VVA technology is currently featured on the R 15, and Yamaha says it helps provide balanced power across the rev range.

The Yamaha MT-25 is powered by a 250cc, twin-cylinder, DOHC, liquid-cooled engine that produces 35.5bhp of peak power and 22.6Nm of peak torque. The engine come mated to a 6-speed manual transmission. The current-generation Yamaha MT-25 employs telescopic suspension at the front and a mono-shock unit at the rear.

Braking duties are performed a single disc brake at both ends. Dual channel ABS is offered as standard with the motorcycle. There is speculation that the new-generation MT-25 will feature an upside-down suspension setup at the front, however Yamaha has not released an official statement.

Cosmetic upgrade that are expected on the new MT-25 are full LED headlamps (which may take its styling inspiration from the recently introduced MT-15), and a fully digital instrument console.

As is, there is no official confirmation about when Yamaha will launch the all-new MT-25 in India, but we think we could see this motorcycle late this year, or early next.

Thoughts About The Upgraded ECU On The All-New Yamaha MT-25

Some time ago, Yamaha said they were stepping out of the commuter segments and concentrating on retailing performance motorcycles in the country. May be the upgraded ECU is a step in that direction for the company. May be the upgraded ECU will help keep performance value losses at bay with the new BS-VI complaint engines. As is, there could be multiple reasons for this upgrade, but we're excited about this means for future Yamaha models in the country.
