Product Reviews      Review part HA-2511

 I recently fitted a K&N HA-2511 filter on my Honda CBR 250R. It took less than 5 minutes to change the filter from the stock filter to the K&N HA 2511. I am extremely happy with the performance of my bike from the very moment I fitted it! There was a definite change in the sound of the bike (much more refined and peppy) and the torque went up instantly. The bike seems to breathe better and run better too, with better pick up, more response and seems to have improved my fuel economy marginally too. All in all a great boost to my bike and to my riding satisfaction.
