Designed for 95” or larger engines with compression ratios between 10.0:1 and 10.75:1 with rpm 3000 rpm - 6000 rpm, ensuring strong pin retention. Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions, and made in the USA give this chain the internal toughness to resist constant flex and impact loads. High-lift springs and adjustable pushrods are required.. Whether running a practice bike, race machine, or trail bike, the 106-5302 delivers consistent performance. Sold as a complete kit.
