Motorcycle Engines, Power Packs & Big Bore Kits

Go big. Shop S&S Cycle T111, T124 and T143 long block engines, bolt-on power packs and big bore performance kits that pair matched cylinders, pistons, cams and gaskets for a big jump in displacement and torque.

Plan Your Build

Power packs and big bore kits need a fuel map or tuner, and many are for off-road or race use only. Check the Emissions filter and the CARB note on each product.

Find Parts That Fit

Engine parts are specific to your engine platform and year. Use the bike search or the Engine filter, and check the fitment chart on each product before you order.
