Overview
Description
Brand new Cylinder Works Big Bore Kit for Yamaha YZ250 (1999–2023). This bolt-on kit takes your stock 250cc to 295cc with a 72.00mm bore, using a nickel-silicon-carbide plated cylinder and a Vertex forged piston for maximum reliability and performance. No case machining required — just install and ride. Includes cylinder, piston, rings, wrist pin, circlips, top-end gasket kit, and power valve hardware. Perfect for riders looking for a serious boost in low-end torque and overall power without sacrificing rideability. Ideal for motocross, off-road, or woods racing setups. Everything is brand new in box, never installed. Located in Southern Vermont — available for shipping or local pickup. Message for questions or more photos.
