Overview
S&S Cycle 750cc Big Bore Kits
The primary purpose of S&S Cycle's 750cc big bore kits is to enhance the performance of smaller engine models, particularly for the Street 500 or Street 750, giving them more power and acceleration. These stock bore cylinder kits are designed to increase the engine displacement by enlarging the cylinder bore, resulting in more power and torque compared to the stock engine, typically by converting a smaller displacement engine like a 500cc or 650cc into a 750cc unit. Many big bore kits are designed to be "bolt-on" upgrades, meaning they can be installed without requiring extensive engine modifications or machining, making them relatively easy to add to a motorcycle. Before ordering, make sure this kit is compatible with your specific street bike model.
