Wiseco Tracker Piston Kit 10.5:1 STD - K0210PS - Harley Touring, Softail, Dyna

The Wiseco Tracker Piston Kit is a standard-size forged piston kit with a 10.5:1 compression ratio, built for V-twin engines with a 4.375-inch stroke and 96 to 103 cubic inch displacement. Riders choose this kit when they want a durable foundation for a rebuild that offers a strong step up in compression over stock without needing oversize bores.

Forged construction is the core of this kit, giving it the strength to handle demanding riding conditions. ArmorGlide skirt coating reduces friction and helps prevent scuffing, while force-fed pin oiling delivers lubrication directly to the piston pin. The 10.5:1 compression ratio is the feature most riders look for when aiming for improved throttle response and torque.

This standard-size kit is best suited to engines with healthy cylinder bores that do not require an oversize piston. It is a practical, well-engineered choice for a V-twin refresh where reliability and a noticeable performance gain are the priorities.

For off-road / closed-course race use only.
