The 2340 filter works perfect on my 2009 Aprilia Mana and I must of shed about 5 lbs from removing the OEM airbox system. To be safe from the rain, I added the 22-8028PK - Air Filter Wrap on it just in case.

Hi Folks,
I am a K&N air filter fan.  I have been using K&N filters for years on my vechicles i.e., 2004 BMW F650GS 652 , 2005 APRILIA Pegaso 650 Strada 660, 2008 HONDA Civic VII Type R 2.0L. It is economicial, green, and powerful for engines.
The question is no K&N air filter for my motorcycle 07 Suzuki AN400s/Burgman K7? That left me disappointed.  I think this model is a hot and popular. Suzuki has already sold this models for over 500,000 vechicles arround the world.  And, this model is manufactured for years. The air filter design is also suitable for K7,K8,K9, K11. I think this evidence would give significant motivation to design an air filter for the Burgman K7+. Why not produce this model's K&N air filter for the benefit of all Burgman riders?
