Inspired by our Pro Stock Drag Race engines, these updated big bore kit utilizes a Ductile Cast Iron liner wrapped in cast aluminum for optimum thermal conductivity and performance. Bolt-in kits do not require machining, rebalancing or engine removal, and include just about everything you’ll need to complete the installation. The biggest cylinder bore that can be installed in a stock crankcase without machining!

S&S does not recommend compression ratios higher than 10:1 for Tri Glide® or other three wheel models (including conversions) due to extra loads caused by the lugging nature of these bikes. Detonation and subsequent engine damage may result.
