Yamaha Chain and Sprockets

Complete Chain and Sprocket Kit  All ProSeries Sprockets are Made in the USA from the harder grade 7075-T6 certified aero space industry aluminum for long life and light weight. They are machined to exact specs with tolerances much more stringent than other aluminum sprockets and many times tighter than OE sprockets. What this means is that your chain will fit the sprocket better and everything will last longer. Additionally, they are chemically etched to give them a uniform, even finish. This process also provides corrosion resistance. Kits include a lightweight 7075-T6 alloy rear sprocket, drilled and lightened case-hardened steel front sprocket, and Gold EK X-ring chain. Upgrade to a colored chain if you like. The lightweight parts and low friction chain will improve your HP 5 to 7 percent at the rear wheel. Important Notes-  -All of our drive kits come with x-ring sealed chains that are appropriately rated for the bike for which they are intended.  -The chain tension on all modern sport bikes should be maintained with a minimum of 2" of top-to-bottom travel to accommodate full suspension movement and prevent premature chain stretching and sprocket wear. - Circle Hole Design or Solid Design (with no holes) generally ship in 1-3 days     - Custom Designs usually ship in 1-2 weeks.
