In 1998, Yamaha Motor launched its new flagship supersport model YZF-R1 (1,000cc), which won acclaim for its exciting performance on winding roads, thanks to the combination of its high-performance engine and lightweight frame. Since then, Yamaha Motor continued its expansion of the YZF-R series through the launch of YZF-R6 (600cc) and YZF-R7 (750cc). And in 2008, YZF-R15 (150cc) and YZF-R125 (125cc) were introduced to India and Europe respectively. The new YZF-R25 is developed not only for the Indonesian market where the popularity of sports models has been increasing, but also as a 250cc supersports model to cater for the global market.

1) Newly-developed high performance two-cylinder engine
The YZF-R25 is equipped with a newly-developed 250cc, liquid-cooled inline two-cylinder fuel-injected engine. In order to promote faster combustion, the new engine was designed using the latest analysis technology to actively generate a tumble (a vertical whirl of air-fuel mixture) in the combustion chamber while obtaining an optimum flow rate of the engine’s air-fuel mixture. As a result, the engine boasts a class-leading power output while also offering a power delivery suited for daily use. In addition, the new engine uses Yamaha Motor’s unique DiASil (Die casting Aluminum-Silicon) cylinders, which offer excellent heat dissipation and lighter weight. This is the first time this technology has been implemented in 2-cylinder engines made by Yamaha Motor.

A simple and lightweight steel frame with minimal curves and welding is employed. The new YZF-R25 offers excellent handling through various features, including the front suspension with 41mm inner tubes, one of the largest in the class, Monocross suspension that contributes to mass centralization, and a rear arm that has the same axial distance ratio as the YZF-R1.

The new YZF-R25 features a sporty and advanced-looking design worthy of the YZF-R title. The mass-forward silhouette and sharply-sculpted rear end inherit the DNA of the R-series. The reverse-slant twin headlights for a sharper look, an air duct that evokes a sense of high performance, shift timing indicator identical to the YZF-R1, and other features are also derived from previous YZF-R designs.
