Cylinder Works 19-20 Yamaha WR 450 F 450cc Standard Bore High Comp Cylinder Kit 13.8:1 Comp 97mm

If you're looking to get more power out of your 2019 or 2020 Yamaha WR 450 F, this high compression cylinder kit from Cylinder Works is a solid option. It's designed to restore lost horsepower and give you a noticeable boost in performance, especially for off-road riding where every bit of power counts. This kit replaces your stock cylinder with a new, well-built cast aluminum one that's ready to handle the increased compression.

What sets this kit apart is the attention to detail in the bore. It features a nickel silicon carbide (NSC) electroplate bore, which is a really durable finish that allows for tighter tolerances. This means less friction when the piston moves, leading to better efficiency and extreme durability over time. The bore is also precision diamond honed to exact dimensions and the right surface finish, which is crucial for ensuring your piston rings seal properly and retain oil effectively. This all adds up to a more powerful and reliable engine.

This kit comes with the Cylinder Works cylinder, a Vertex piston, and all the necessary gaskets to get the job done. It's a complete package aimed at giving you a competitive edge compared to buying individual OEM parts. When you're rebuilding your top end, having a well-matched piston and cylinder with the right bore finish makes a big difference in how the engine performs and how long it lasts.
