Yamaha YZF R15 Features






Liquid-cooled

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.

DiASil Cylinder

The DiASil Cylinder was born from YAMAHA’s world-class aluminum die casting technology.

DiASil Cylinders are all-aluminum cylinders made by YAMAHA’s proprietary aluminum die casting technology. An aluminum alloy with 20% silicon content is used to create a very hard, reliable cylinder surface, making conventional iron sleeves obsolete. As a result, the entire cylinder can be made of aluminum, a better conductor of heat, which means the cylinder delivers better heat dissipation and less weight. (Aluminum’s heat conductivity is 3.1 times that of iron.)

Fuel Injection

Fuel injection is used to ensure excellent fuel efficiency as well as environmental friendliness.

The two components of the fuel injection mechanism used in YZF-R15, a) the sensors that gather information on the engine’s operation, and b) the fuel supply system that supplies gasoline, have both been designed to be lightweight and simple. The sensor component uses only 4 sensors (Red blinking points) to gather large amounts of information relating to engine operations, which is sent to a small 26-pin ECU, which in turn calculates the optimum fuel supply. The fuel supply component consists of a small, fuel pump, modularized regulator and filter, and a small injector, all of which come together to enable a lightweight, compact form. The injector injects finely atomized spray of fuel through 6 hole type injectors.

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.

The use of a 4-valve combustion chamber (a combustion chamber with 2 intake and exhaust valves each) has allowed designers to layout the spark plug at the center of the combustion chamber for better flame propagation.

In addition, the intake and exhaust valve angles have been kept small to achieve optimum combustion chamber configuration. Yamaha aimed at minimizing the surface area/volume ration (S/V ratio) in the combustion chamber, which is key to improving fuel efficiency.

Humachine Technology

A sharp form that cuts through air. Inheriting the “R series” gene.

YZF-R1 and YZF-R6 are equipped with under cowls that are based on the image of a diffuser, to give them the best form for aero-management. These are not cowls for simply enclosing the engine, but forms composed of blade surfaces that actively control airflow. This spirit has been directly inherited by YZF-R15.
