Description REV PERFROMANCE PREMIUM HALF TOOTH SPROCKETS Take your kart’s performance to the next level with our Premium 219 Half-Tooth Sprockets, precision-engineered for serious 2-cycle kart racing.Built for drivers who demand the finest control, these sprockets let you fine-tune gear ratios with unmatched accuracy — no front sprocket change required. Despite the name, there’s no “half” tooth. Instead, each tooth is subtly repositioned using advanced machining geometry, allowing a 219-pitch chain to sit perfectly in the valley while altering the sprocket’s rolling diameter for true half-tooth adjustments. Each sprocket is CNC-machined from 7075-T6 aircraft-grade aluminium with tolerance within 0.01 mm, ensuring flawless concentricity and minimal drivetrain friction. The result? Smoother power delivery, reduced wear, and faster lap consistency. After extensive R&D and track testing, we’ve perfected the pitch for superior load distribution — you’ll notice how precisely the chain engages each valley, providing maximum efficiency and drive response. Available in sizes from 69.5T to 80.5T, the 219 Half-Tooth range is the ultimate solution for racers chasing performance gains where every tenth matters.
