Clutch Rollers & Sliders for 2 Stroke Engines - 15 x 12 Rollers

In 2-stroke CVT systems, clutch rollers and sliders determine how the variator responds to engine RPM, affecting acceleration, takeoff behavior, and overall shifting smoothness. The 15 x 12 size is a common specification for many Minarelli-style and Jog-type engines used in scooters and lightweight recreational vehicles. Over time, rollers can flatten and sliders can wear down, causing inconsistent shifting, noisy operation, or reduced performance. Replacing these components helps restore proper belt travel and allows for performance tuning by adjusting roller weight.

This category may include:

• 15 x 12 variator rollers for 2-stroke CVT engines
• Variator sliders for smoother ramp movement
• Multiple weight options for tuning acceleration and top speed
• Parts compatible with Minarelli, Jog, and similar 2-stroke platforms
• Components suited for various scooter and small recreational vehicle brands

Additional notes about this collection:

• Helps correct poor acceleration, hesitation, or uneven shifting
• Allows riders to fine-tune performance based on terrain and riding style
• Recommended when rollers show flat spots or when rebuilding the CVT
• Designed for accurate fitment when matched to the correct roller size
