Customer Feedback

Great replacement to the factory cabin filter. Easy install ( two minutes ) No more dealer rip off prices. Been dealing with K&N since my days in the motorcycle business ( Suzuki & Yamaha ) in the seventies and eighties on long Island.

For one thing, I like the fact that the air filter will probably outlast the life of the bike. How could you go wrong with that ?!Installation was easy, only took about 10 minutes. I have used K&N before and was happy the last time I used it on my 1979 Kawasaki 650 SR.
