S&S Cycle Big Bore Kits

These 129-inch and 132-inch kits for 2017-2022 Harley-Davidson Milwaukee Eight engines are literally huge.

S&S Cycle loves raw, unadulterated, thumping, makes-your-heart-skip-a-beat kind of power, and that’s the very stuff the company specializes in. This obsession with power is further proven out by its latest efforts for the Milwaukee Eight powered Harley-Davidson models. Its 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 cubic-inch to a fire breathing 129 cubic-inch or the 114 cubic-inch models to 132 cubic inches of tire-melting power. The latest is a 4.32-inch 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 U.S.  For more info and detailed specs, check out https://www.sscycle.com/feature/performance-kits/129-132-cylinder-piston-kits

RT Exhaust

Sawicki Speed has introduced the “RT” line of exhaust systems for Harley-Davidsons and Indian Motorcycles.

Royal-T Racing founder Patrick Tilbury made a name for himself as lead fabricator for Jesse James’s Austin Speed Shop. His love for motorcycle racing and desire to blend performance with aesthetics led to the pie-cut welded muffler and CNC’d end cap that Royal-T became famous for. Sawicki Speed’s parent company, Proto Titan, was already manufacturing the final rounds of exhausts for Royal-T when they made the bold choice to acquire the design rights and include it in Sawicki Speed's lineup of performance exhaust offerings.
