S&S Cycle - 129” and 132” Big Bore Kits for 2017-2022 HD M8 engines

VIOLA, WI – August 11, 2022 – (Motor Sports NewsWire) – We love raw unadulterated thumping, makes your heart skip a beat kind of power and that’s the very stuff S&S Cycle specializes in. This obsession with power is further proven out by their latest efforts for the Milwaukee Eight® powered Harley-Davidson® models.

Their bolt-in 129/132 Cubic Inch (that’s well over 2000cc for you metric folks) Big Bore Kits are just this side of monstrous. Taking the stock engine from a mild mannered 107 CI to a fire breathing 129 CI or the 114 CI models to 132 cubic inches of tire melting power. Their latest is a 4.32” bore and is slated for 11:1 compression ratio so it’s happy with pump gas, but will still complement a high lift cam. No case mods, no engine removal; just a massive set of jugs, designed, tested, and manufactured here in the USA.

About S&S Cycle

The performance aftermarket, both 2 and 4 wheel was born on race tracks around the world. Enthusiasts in their single car garages grinding aluminum and welding steel late into the night, all in the hopes of a quicker ET or a higher top speed. For many it stayed on the local tracks, a select few translated their passion for performance into global enterprises. In 1958 George Smith chose the latter and across the next sixty plus years S&S Cycle would mature from grassroots racing effort to world class manufacturer and OEM partner. All the while racing has remained a core competency, from speed records at the Bonneville Salt Flats to multi year championships in American Flat Track, S&S is the go to for high performance on and off the race track.
