The name S&S has become synonymous with high performance Harley-Davidsons. For decades riders and bike builders wanting to get bucket-loads of power without having to undertake excessive modifications have chosen S&S Big Bore Kits, thanks to their easy installation, reliability, and spine-rattling performance. And now Harley’s newest powerplant, the Milwaukee-Eight is set to receive the Big Bore treatment.

There’s been a lot of discussion about some of the great features of the M8 engines, but one massive benefit has regularly been overlooked – there’s heaps of room for more cubic inches. This means that bolt-in big bore kits can offer massive displacement increases that translate to insane power. S&S’s M8 Big Bore Kits are the biggest bolt-in cylinders ever produced for Harley-Davidson motorcycles.

An S&S Big Bore Kit can take your 107 cubic inch M8 up to a massive 124 inches. Got a 114 inch or 117 inch model? Drop in a Big bore Kit and get an almost incomprehensible 128 cubic inches. The kits are 100% bolt-on with no machining required. They are available in wrinkle black with or without fin highlights, and also in CVO granite black. Proudly distributed in Australia and New Zealand by Rollies Speed Shop.
