Dirt Tricks Zirconium rear sprocket - Yamaha YZ/YZF

The Dirt Tricks sprocket was designed and patented by Dirt Tricks president and engineer Greg Burns in 2002, using his knowledge of aerospace steel, heat treatments and FEA stress analysis. As an expert in desert racing, Greg grew tired of replacing aluminium sprockets every two months. His goal was to create a sprocket that would last an entire season of hard riding, yet be comparable in weight to aluminium. Thus, the Dirt Tricks sprocket was born. It took two years of development and testing, but the end result has proven to be the toughest, most durable off-road sprocket available. Our Chrome rear sprocket is 2.5 times stronger than stainless steel and features a unique "minimalist" design and look. We back these sprockets with a one-year warranty: if you wear it out, we'll replace it. Our black and chromatic rear sprockets use our latest design and are a revolutionary change in weight and colour. Our new Dirt Tricks Zirconium sprockets are 57 g lighter than our chrome-plated design, comparable to most performance aluminium sprockets and lighter than the twin metal designs available. The new coating on these sprockets reduces friction by up to 50%, increases durability and looks sharp! Our Special Edition sprockets will outlast any sprocket on the market, and we back that up with our 1-year warranty.
