Rear Sprocket - SKU KX85

The World's Toughest Sprocket!

The Dirt Tricks Rear Sprocket was designed and patented in 2002 using advanced aerospace-grade steels, specialized heat treatments, and FEA stress analysis. The goal was simple: create a sprocket that would last an entire season of hard riding while remaining comparable in weight to aluminum.

After two years of development and testing, the Dirt Tricks sprocket was born and has since earned a reputation as the toughest and most durable off-road sprocket available.

Our Black, Chromatic, and Raw Rear Sprockets feature our latest design, representing a significant advancement in weight reduction, durability, and appearance. These sprockets are approximately 2 ounces lighter than our original design, making them comparable in weight to many performance aluminum sprockets while offering substantially greater strength and longevity. Their advanced coating technology reduces friction by up to 50%, increases wear resistance, and provides a premium finish that stands out on any bike.

Backed by our industry-leading wear guarantee, Dirt Tricks sprockets are engineered to outlast and outperform anything else on the market.

The World's Toughest Sprocket. Proudly designed, engineered, and manufactured in the USA.
