Race ready
This K&N filter will allow your sport bike to breath better. Gives its the power it needs for those track days and if you don't live in a windy city then even street driving can be better. You will notice the decreased acceleration time from a stop. This is a well made product like all the products from K&N are. Enjoy those track day's. Ride safe.

Track use only
Do not use on the street.This filter is for max air flow on the track. It does not filter as well as the street version.It you want max flow for track use this is your filter.
