S&S has been building big bore kits since the 60s and we have it down to an absolute science. Our latest efforts are aimed at the Milwaukee Eight® platform (2017 and newer big twins) and opens up a whole new level of performance for these engines. Combining a new short skirt style forged piston with our 4.25” cylinders to net a tire melting 131 cubic inches! Specifically designed to be paired with our 4.625” stroker crank and easily produce 145 Hp and 145 lb ft. We’re looking forward to seeing the beasts that will get built around it!
