Because it uses a 20% silicon aluminum alloy, it is possible to create a cylinder wall that is so hard and durable that it eliminates the need for a conventional steel cylinder sleeve. And, because the cylinder is all aluminum, it has excellent heat dissipation qualities (cooling capacity is improved by 60% and reduces engine weight (by 30%) at the same time.

YZF R15 makes use of forged piston (India’s first) which enables lighter piston design and excellent power developement.

YZF R15’s 4-valve combustion chamber adopts centrally mounted spark plug and six hole type injector which leads to path breaking performance.
