The major manufacturers have started to extend the warranty period for vehicles sold in Japan from one to two years in a bid to increase customer satisfaction.
On April 1, Yamaha will begin to offer a longer warranty for all 29 types of motorcycles it sells in the domestic market. Kawasaki  and Suzuki are also considering a similar move.
Honda doubled its warranty period to two years in February and Harley-Davidson also offers a two-year warranty in the Japanese market.
Yamaha's new warranty will not impose a limit on the total distance that the motorcycle can be driven during the coverage period, company sources said.
