Cylinder Works 08-09 Honda TRX 700 XX 700cc +3mm Big Bore Cylinder Kit 727cc 10.0:1 Comp. 105mm

This Cylinder Works big bore cylinder kit starts with a 105mm bore size, a +3mm increase over stock, pushing your 2008-2009 Honda TRX 700 XX from its original 700cc up to a full 727cc. The cylinder itself is constructed from a high-quality 2618 aluminum alloy, chosen for its strength and durability, which is crucial when you're increasing displacement and aiming for more power. This material choice helps ensure the cylinder can handle the increased pressures and heat generated by a larger engine.

Inside this kit, you'll find a hand-matched Vertex piston, specifically sized for the 105mm bore, along with a complete top-end gasket kit that includes all the necessary O-rings. This all-in-one approach simplifies the rebuild process and offers cost savings compared to sourcing each component individually from the OEM. The kit is designed to look like the original cylinder externally, maintaining a stock appearance while delivering significantly improved performance and increased horsepower. With a compression ratio of 10.0:1, this kit is built for a noticeable boost in engine performance.

When undertaking a big bore project like this, it's important to ensure all supporting components are in good condition. This includes checking your crankshaft, connecting rod, and ensuring proper fuel and ignition tuning to take full advantage of the increased displacement. This kit is a solid option for riders looking to extract more power and performance from their TRX 700 XX.
