Flywheel Assemblies for 1986-’03 Sportster® Models and S&S SB-Series

S&S now offers flywheel assemblies to replace the stock flywheels in 1986-’90 and 1991-’03 Sportster models.

S&S flywheel assemblies for 1986-’03 Sportster models are of five piece design and feature a large tapered sprocket shaft and pinion shaft. Since the stock flywheels for these engines do not have removable mainshafts, S&S engineers designed the pinion shaft with the same larger, stronger taper as the sprocket shaft.

Why put your engine back together with stock flywheels when you can upgrade to S&S quality?
