MALOSSI MHR Replica Cylinder Kit Ø40.3 - Pin Ø12 H20 (manufacturer reference 3112199): a thermal group component designed for urban 50 cm³ engines requiring precision and robustness. This cylinder kit follows the standards of the MHR Replica range with a generous bore and an aluminum construction for optimized heat dissipation and good performance in city heat.

• Bore diameter: Ø40.3 mm
• Material: aluminum (machined body)
• Piston pin: Ø12 (H20)
• Category: Thermal group — urban use

Designed for mopeds and urban 50 cm³ road bikes, this kit is aimed at riders who want to enhance reliability or restore the top-end while respecting factory tolerances. The aluminum alloy facilitates heat dissipation and allows for a more uniform break-in of the sleeve. Particularly suitable for installations on the most common 50 cm³ models: VENT DERAPAGE 50 RR, SHERCO SM 50 RS, and FANTIC XM 50 PERFORMANCE.

For safe and durable installation, ensure the piston/sleeve fit is checked, use a torque wrench, and follow the break-in and carburation recommendations. If in doubt, entrust the installation to a specialized workshop to guarantee the sealing and longevity of the thermal group.
