Flywheel Assembly - 4-5/8" - w/o Sprocket Bearing Race - Replacement for SE 120R 124" Motor

The S&S Cycle 320-0523 flywheel assembly is engineered for high performance and durability, designed specifically for use with SE 120R 124 inch motors. Crafted from premium 4140 steel, this three-piece flywheel with an integral main shaft provides unmatched strength and reliability for demanding applications. Its larger 1.671-inch crankpin ensures enhanced strength and stability during high torque conditions, making it a suitable upgrade or replacement for stock components. The assembly is designed for direct fitment into stock crankcases, requiring no modifications, which simplifies installation and minimizes downtime. Made in the USA, this flywheel assembly exemplifies quality craftsmanship and precision manufacturing. It is intended for use with a Timken bearing conversion, sold separately, and does not include the sprocket bearing race, offering flexibility for custom setups or existing configurations. Whether you're restoring a classic motorcycle or upgrading a high-performance build, this flywheel assembly delivers the strength and reliability essential for extended riding and racing conditions.
