The KN-204 was the perfect fit for my new Yamaha 2015 FZ-07 750cc. I really like the convenience and high-quality metal of the bolt-head, and the excellent seal of the filter. Thank you so much for anticipating the market!

I used the K&N RC-2540 filter as an air filter for my Yamaha Towny scooter. It fits perfect and the chrome end dressed up the bike.

I have a fz6r Yamaha and my bike drives so much better because of the new filter. A must buy if you have this bike.
