TOKYO -- Japan's Kawasaki Heavy Industries and Suzuki Motor have updated motorcycle engines common in the 1980s to conform with today's environmental standards, aiming to roll out the two-wheelers in developing markets in Asia.
Kawasaki will release the Ninja ZX-25R next year in Indonesia and Thailand. The 250cc model will be the first one of its class in 12 years to adopt the four-cylinder engine that was a feature of larger bikes.
