The 96.96 mm bore size maintains your stock displacement while the advanced skirt coating minimizes friction losses throughout the RPM range. Whether you're rebuilding after a top-end failure or prepping for a new season, this complete kit delivers the precision fit and materials your YZ450F demands.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
