Engineered to maximize displacement for 2007–2016 models, the Rocket Performance Garage Big Bore Cylinder Kit transforms standard 96" and 103" engines into high-capacity 110" powerplants. This hard parts upgrade utilizes a 4.375" stroke to deliver substantial torque and horsepower gains, making it an ideal solution for riders seeking enhanced performance from their existing powertrain without the need for a complete engine replacement.
The kit features CP forged pistons designed to withstand the increased mechanical demands of the larger bore. With a compression ratio of 10.5:1, these components are optimized for efficient combustion and robust durability, ensuring reliable operation under high-stress conditions. This precise engineering allows for a significant performance uplift while maintaining the structural integrity required for sustained high-RPM use.
