Motorcycle Sprockets & Chain and Sprocket Kits
Sprockets are the gears that the chain wraps around and drives, and their condition has as much to do with how your drivetrain feels and performs as the chain itself. A new chain on worn sprockets is money spent in the wrong order. A worn rear sprocket with hooked teeth that no longer mesh cleanly with the chain creates a drivetrain that feels imprecise, delivers power inconsistently, and wears the new chain to the profile of the old sprocket rather than running in cleanly from a fresh starting point. Sprockets are wear items just like chains and tires, and treating them as such by replacing them as a complete set when any component reaches the end of its service life is the approach that delivers the longest service life, the most consistent power delivery, and the best overall value from your drivetrain investment.
Sprocket selection also gives you the opportunity to tune your motorcycle's gearing for your specific riding style and terrain without any internal engine modifications. Moving one tooth on the front countershaft sprocket shifts the overall drive ratio more significantly than moving two to three teeth on the rear, making front sprocket changes the most efficient gearing adjustment for riders who want a noticeable change in acceleration or top speed from a single part swap. Rear sprocket changes allow finer gearing adjustments and are available in a wider range of tooth counts and materials including steel, aluminum, and in some cases titanium for weight-conscious applications. Mad Lads Moto stocks front sprockets, rear sprockets, and complete chain and sprocket kits for dirt bikes, motocross bikes, enduro machines, trail riders, street bikes, and adventure tourers across all major makes and models. Here is what we carry:
- Front Countershaft Sprockets - Replacement front sprockets in OEM tooth counts and alternative gearing options for riders who want to raise or lower their overall drive ratio, available in steel construction for maximum durability across all major chain sizes and motorcycle applications.
- Rear Wheel Sprockets - Replacement rear sprockets in OEM and alternative tooth counts in steel and aluminum constructions, covering standard replacement and gearing change applications for dirt bikes, motocross machines, enduro bikes, trail riders, street bikes, and adventure tourers.
- Complete Chain & Sprocket Kits - Bundled kits that include a front sprocket, rear sprocket, and drive chain in a single purchase, ensuring all three components start fresh together at the same wear baseline and eliminating the compatibility concerns that arise from mixing components from different purchase timelines.
- Sprocket Hardware & Bolts - Rear sprocket bolts, lock nuts, sprocket carriers, and mounting hardware for sprocket installation and for machines where the original mounting hardware has worn, stripped, or been lost during previous sprocket service.
Aluminum rear sprockets are one of the most popular weight reduction modifications on motocross and enduro bikes, and the weight savings they deliver is genuinely meaningful because the rear sprocket is rotating unsprung weight that affects both handling and acceleration. A steel rear sprocket on a typical full-size dirt bike weighs significantly more than an equivalent aluminum sprocket, and that weight reduction at the wheel contributes to quicker steering response, reduced rotating inertia, and better acceleration feel. The tradeoff is durability: aluminum sprockets wear faster than steel and require more frequent replacement, particularly in sandy and abrasive conditions where the softer aluminum teeth erode more quickly than steel. For motocross racers and enduro riders who inspect and replace sprockets regularly as part of their maintenance routine, aluminum is the right choice. For trail riders and recreational riders who want maximum service life between replacements, steel delivers better long-term value. We stock sprockets and kits for Honda, Yamaha, Kawasaki, Suzuki, KTM, Husqvarna, Beta, GasGas, and more.
