Chain Pitch: #219
Material: 7075 Aluminum

Tooth Range: 67.5T - 84.5T in half-tooth increments
Full System Weight: 15 oz (with hub and guard)

This one-piece #219 sprocket from Smoker Performance lets you fine-tune gear ratios with half-tooth steps that fall between standard full-tooth jumps. Machined from 7075 aluminum and 1mm thinner than typical options, it reduces rotating mass and chain drag while simplifying install on race day.

Performance Tips: Test half-tooth jumps like moving from 72T to 72.5T on tight tracks to improve acceleration out of corners without losing top speed. Beginners should log lap times with each change while experts monitor chain wear and polar moment of inertia gains.

The single-piece design bolts directly to the Smoker Performance mini sprocket hub. Pair it with a 200 mm carbon guard for 68-72T sizes or a 220 mm guard for 73-85T applications. The laser-etched logo and lightening holes keep weight to a minimum while maintaining strength.

How does the half-tooth sizing improve kart performance?

Half-tooth increments from 67.5T to 84.5T allow precise gear ratio tuning between standard full-tooth steps, helping both beginner and advanced drivers optimize acceleration and top speed for specific track conditions and #219 chain setups.

Will this ultra-light sprocket fit my existing mini hub and guard?

Yes, the one-piece 7075 aluminum sprocket mates directly to the Smoker Performance mini sprocket hub. Use the 200 mm carbon fiber guard for 68-72T or the 220 mm version for 73-85T to complete the lightweight assembly.
