Yamaha YZF-R15: The Urban super-Sport

By Source: Official Website

Yamaha YZR - R15
"Harmony between rider and machine." YAMAHA's Human Technology involves studying the form of the motorcycle actually in motion with the rider on it. The R series is the embodiment of a wide frontal space that protects the rider, an easy to ride seating area that gives riders the freedom of movement and allows them to steer effectively, the glamorous tail treatment that takes into account the management of airflow behind the rider, and and a sensual racing form that brings all 3 of these elements together in a harmonious package. These characteristics have been splendidly reproduced in the YZF-R15.

The model also incorporates a multitude of adjustments for the Indian market including seat shape that allows for tandem riding, tandem grips that are easy to grip and also contribute to the super-sport design, and a riding position that takes into account comfort, etc. In other words, the YZF-R15 is characterized by a hybrid design that combines the world-class design of the "R" series with localized functions. The YZF-R15 was created to lead the super-sport category in India.

One characteristic of YZF-R15's new engine is that it is liquid-cooled. This is the first India-made model with cooling method in the Indian market! Liquid-cooled engines provide stable performance, reduce vibrations, and offer a high quality ride. The engine is surrounded by a water jacket in which coolant liquid circulates to cool the engine. YZF-R15 uses a special compact and lightweight aluminum radiator and a body design that utilizes airflow for heat dissipation. The liquid-cooled, 4-stroke, SOHC, 4-valve engine delivers 17PS/8,500rpm. The bike has a displacement of 149 .8cc.

The newly developed engine delivers agile riding performance, and excellent performance on straight stretches of road as well as on winding roads. YZF-R15 also delivers excellent environmental performance. These traits are a must for an "urban super-sport." The ride is unprecedented in terms of both excitement and quality.

The frame, which forms the basis for riding comfort and handling performance, is a Deltabox frame which delivers superior rigidity balance. This frame was designed to provide the best balance in longitudinal, lateral, and torsional rigidity. The synergy created by optimizing each dimension delivers a solid riding feel as well as comfort and agile riding performance.

Fuel injection is used to ensure excellent fuel efficiency as well as environmental friendliness. In order to maximize the efficiency of the fuel injector, which injects the optimum amount of fuel for different amounts of intake air, YZF-R15 is equipped with a large 3-liter air cleaner. The duct area of the intake duct was designed optimally to optimize the flow of intake air.

YZF-R15's engine delivers excellent response, fuel economy, is environmentally friendly and a comfortable ride. YZF-R15 is equipped with this all-aluminum cylinder called the DiASil Cylinder and a forged piston, the same type of piston used in YAMAHA's supersport bikes. The fact that both the piston and cylinder of YZF-R15 are all-aluminum ensures excellent heat dissipation, eliminates heat-induced engine power loss, and helps improve fuel efficiency.

YZF-R15 is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out. In particular, it reduces annoying "sinking" when riding tandem.
