Product Information

Full details

The Athena Big Bore Race Cylinder Kit is designed for adult riders seeking enhanced performance from their Suzuki LT-R 450 2X4 (2006-2011). Its key benefit is increased power output due to a larger bore and improved cooling. A caveat is that it requires specially designed, high-performance power valves, meaning OEM parts cannot be used. This kit features an aluminum cylinder with a nickel-carbide coating and larger water jackets for superior heat dissipation, a forged piston with a molybdenum coating for durability, and high-performance, hard-anodized power valves.

Poor performance or sputtering

Check for air leaks in the intake system, verify the fuel mixture is correct, and ensure the newly installed power valves are functioning correctly.

Overheating during operation

Confirm coolant levels are adequate and the cooling system is properly bled. Ensure there are no blockages in the water jackets or radiator.

Unusual engine noises

Immediately stop the engine and inspect for loose components, incorrect piston-to-cylinder clearance, or issues with the power valves.
