The YZF-R25 has been developed both as a global model and leading force for business scale expansion as set out in Yamaha Motor’s new medium-term management plan (2013-2015). Therefore, the new model is also developed with both the ASEAN and developed markets in mind.
Using the concept ‘superbike you can ride every day’, the new YZF-R25 achieves a high level of performance and stylistic features worthy of the ‘supersport’ title through class-leading engine output, as well as a lightweight body and design that continue its lineage from the YZF-R series. In addition, the new model is nimble and easy to handle for everyday use as well as offering an exhilarating ride in a wide variety of scenarios.
In Indonesia, the popularity of sports models has been increasing in recent years. In response to this, YIMM is carrying out brand strategies that focus on the sporty side of motorcycling, along with existing marketing activities centered on motorcycle racing. For example, YIMM launched Yamaha Motor’s flagship supersport models – the YZF-R1 and YZF-R6 – last November, and in May this year, YIMM kicked off its manufacture and sale of the YZF-R15. The launch of the YZF-R25 further expands the YZF-R series lineup. With this launch, there will also be initiatives for further sales expansion and brand strength improvements.
Development Aims
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.
Main Features
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.
2) Mass-centralized lightweight body
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.
3) Body design inherited from the YZF-R series
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.
