Polini 1149612 CrankshaftRef : POL00624A / 1149612

POLINI For Race crankshaft, manufacturer reference 210.0081, developed for 50 cm3 Minarelli AM6 engines in enduro / motard and tuning configuration. Designed around a full circle and a stroke of 39 mm, this crankshaft aims to optimise carburation management and engine group inertia for demanding uses.

• Forged connecting rod: robust construction to better withstand high-rev constraints.
• Specific balancing: reduces vibrations for a more consistent rev range.
• C4 bearing pack: two high-speed bearings included for increased durability in severe conditions.
• Improved flywheel side bearing: inner diameter 20 mm, a technical solution designed to enhance durability on track and off-road.
• Targeted for tuning: intended for high-performance configurations where mechanical reliability and engine response are sought.

The POLINI For Race is aimed at riders who modify the transmission and carburation of their AM6 and seek a robust crankshaft, ready to withstand sustained revs. Compatible with many motorcycles equipped with the Minarelli AM6 engine block — for example Vent Dérappage 50 RR, Sherco SM 50 RS, and Rieju MRT 50 SM — it integrates into performance-oriented setups while remaining easy to install for a skilled DIYer.
