YAMAHA 49T Alloy Rear Sprockets Silver YZ/YZF/WR
ALLOY RACING SPROCKETS presented by MTC Racing
Sprockets are made from blocks of high quality heat-treated 7075 T6 aluminium, once machining is complete they are then anodised for even greater wear. The teeth are machined to the latest standards for maximum chain/sprocket life, which in turn provides a more efficient power delivery over the life of the sprocket. Optimal light weight design and CNC machined for performance and lifespan .
These alloy racing sprockets are made on precision computer controlled equipment. Machining is carried out on a gear hobbing machine. The teeth and the outside diameter are cut at the same time, this makes sure the teeth are concentric to the sprocket centre. Most OEM’s demand a maximum run-out of 0.5mm, but this machining method allows these racing sprockets to have a maximum run-out of only 0.2mm more than twice the industry standard.
These are high quality aftermarket CNC machined alloy rear racing sprockets as currently used on our race bikes.
•Computer designed to achieve ultimate strength at minimum weight.
•Made from high quality 7075-T6 aluminium alloy and anodized for even greater wear.
