S&S Cycle 91-03 XL 3-13/16in Stroke Flywheel Assembly

When you're rebuilding the heart of your 1991-1999 Harley-Davidson 1200cc Sportster, the flywheel assembly is a critical component. This S&S Cycle flywheel assembly is built to replace your stock units, giving you a solid foundation for a powerful engine build. It features a 3-13/16 inch stroke and a 7-7/8 inch diameter, designed specifically for those Sportster models.

These flywheels are CNC machined from heat-treated, closed-die steel forgings. This construction method makes them stronger than the original cast iron or later-style steel flywheels you might find. They are also dynamically balanced and come fully assembled with S&S Cycle's own mainshafts and heavy-duty 6.926 inch connecting rods. This assembly is balanced to work with S&S Cycle's 3-1/2 inch bore pistons, ensuring a well-matched and robust rotating assembly for your engine.

This flywheel assembly is a substantial upgrade for anyone looking to get more performance and reliability out of their Sportster engine. It's a key piece for building a more powerful and durable drivetrain.
