Wow I’m thrilled with my new flywheel assembly from S&S as a casual tinkerer I was looking to upgrade the flywheel on my custom big twin build the 4-1/4 stroke and beefy 8-1/2 diameter flywheels on this assembly really bring the power compared to stock flywheels and other aftermarket options I researched this S&S flywheel delivers smoother torque and higher revs exactly what I was going for the fit and finish is fantastic clearly made in the USA with S&S’s usual attention to detail it bolted right up to my crankcase without issues I’m impressed that this is the same assembly used in their top-of-the-line SH80 engines even though I’m just a weekend wrencher I can feel the quality difference when I ride my only gripe was the shipping delay but S&S packaged the flywheel assembly very securely despite the wait it arrived in perfect condition with no damage considering the boost in performance this flywheel gives my ride I can forgive a little delay in shipping overall this is a top-notch flywheel upgrade for anyone looking to add more power to their big twin V-twin

This flywheel assembly from S&S is decent quality and seems to work fine in my custom V-twin build, but I was hoping for smoother performance based on the price.

The flywheel seems good so far but the finish could be better, it works fine for the price though the instructions weren’t great.

Well isn’t this just the best little flywheel assembly I ever did see I’m just tickled pink that S&S went and made this top of the line 4-1/4″ stroke flywheel for all us motorcycle enthusiasts it would be 5 stars but then I wouldn’t have anything to irrationally complain about in my next review

Wow, this new Flywheel Assembly really screams overcompensation. I’m sure revving your ridiculously overpowered engine will make you feel like a big, strong man, but nothing says “I have a small penis” like trying to look cool zooming around town.

This flywheel assembly from Brand X is just amazing, cutting-edge technology – truly revolutionary and an absolute game changer that makes all other flywheel assemblies obsolete now.
