Cylinder Works Big Bore Kit

Adding displacement is one of the most direct routes to more power from a single-cylinder engine. Cylinder Works' Big Bore Kit enlarges the Raptor 700's bore to increase displacement, giving the engine more torque and pull across the rev range.

Why riders choose it

• More displacement for added torque and power
• Pairs naturally with a top-end refresh, since the top end comes apart for the job anyway
• A bigger step than a standard bore or high compression rebuild
• From Cylinder Works, a company focused on cylinders
