K&N provides 07 KLX250 air filter
but is it the same as KLX250SF?

or any other good air filter !

Thx

Btw , how about GPR exhaust system?

GPR or FMF?

 

depends if you wanna do any offroad riding. if so id go with a twin air. and yes it is the same filter.

 

Even with some moderate off-roading, the K&N is just fine.

Otherwise check out TwinAir and Uni filters.

Never seen GPR exhaust?

 

thx bro, & i should go for a mega bomber or not? or just a slip on is okay?!

 

Dusty conditions, foam filter. That's why you don't see K&N on many, if any, motocrossers, but lots of roadracers and drag racers. Those that do use K&N will have the foam filter sock - whatever they call it - on any K&N. Kind of says it all - they use foam over their own filters when it's dusty.

 

+1 on foam. Ran UNI on my KLX and it was great. K&N isn't even an option (not that I'd go with it anyway) on my KTM.

 

Have to agree about K&N and dust. I'm fine in the winter but whenever I pull the filter in the dry season, there's a film of fine dust on the anti backfire screen even when I keep the filter oiled. I'd rather run the foam but it's so restrictive and the little KLX needs all the help it can get.
