Rear gears for motocross and enduro - power, traction and drive precision

Rear sprockets are the workhorse of your final drive, setting how your MX/off-road bike puts power to the ground. The right sprocket helps you hook up out of corners, climb technical hills, and keep the bike calm in deep sand or hardpack. If you’re burning through chains, getting inconsistent acceleration, or fighting a gearing that feels too tall or too short, a fresh rear sprocket matched to your setup is a fast, measurable fix—no matter if you ride in a jersey and goggles on a track or in body armor and knee braces in the woods. When choosing, start with fit: make sure the tooth count, bolt pattern (PCD), center bore, and offset match your hub and model year. Next is material and construction: steel lasts longest for muddy enduro and wet grit; aluminum drops rotating weight for snappier response on MX and hardpack; hybrid/bi-metal styles balance wear and weight. Pick gearing for conditions and engine character—more teeth for tighter trails and quicker drive, fewer teeth for faster tracks and longer straights. Finally, plan maintenance: keep chain tension correct, clean after muddy rides, and check alignment to avoid rapid tooth wear. Replace the sprocket when teeth look hooked or sharp, the chain rides up the teeth, or you see uneven wear from misalignment. Common mistakes are mixing a worn chain with a new sprocket, and changing tooth count without considering chain length and wheelbase adjustment. Tip: Mark one tooth with a paint pen and inspect it after each wash—if it’s thinning or hooking first, your chain alignment or tension is off.
