RENTHAL YAMAHA TWINRING BLUE REAR SPROCKET - 49T

A long lasting durable off-road sprocket developed over 5 years. The unique flat face design keeps weight to a minimum and means the Twinring rear sprocket is as narrow as a standard sprocket. Outer is expanded at 200°C and then fitted to inner, creating a permanent bond for the life of the sprocket.

With some of the biggest motocross names in the world, including Ryan Dungey, Eli Tomac, Jeffrey Herlings and Antonio Cairoli to name a few, Renthal are the number one source for providing world championship winning sprockets to the world's fastest riders. The quality is undeniable, and the results speak for themselves; Renthal are far and above leading the way when it comes to premium quality sprocket technology.

Features:

• The inner ring of the unique Renthal® Twinring® is engineered from Ultralight 7075 T6 Aluminium. This keeps the weight of the Twinring® to a minimum.
• Renthal® Twinring® feature a Electroless Nickel Coated steel. This ensures an ultra long service life of the sprocket, providing you with maximum power transfer longer than ever.
• Each Twinring® that leaves Renthal's engineering facilities in the UK is individually CNC machined to the tightest possible tolerances, ensuring an accurate and reliable fit.
• The Outer ring is expanded to 200°C to be fitted to the inner ring. Cooling creates a permenant bond. Flat socket set screws prevent lateral movement between the rings in high velocity impacts.
• Twinring® feature Renthal's self cleaning mud groove technology between each tooth. This prevents mud build up that traditionally leads to quicker wearing components.
