Description
If you’re running a CRF450R in 2017-2018 spec, a high-compression cylinder kit is one of the most direct ways to unlock measurable power gains without major engine work. This Cylinder Works kit delivers a bolt-on solution that respects OEM tolerances while pushing compression higher—meaning faster acceleration, better throttle response, and improved mid-range pulling power across the board. Pair it with the matched Vertex pistons included in the kit, and you get a cohesive package engineered to run cleaner, quieter, and more reliably than stock.
