07 fsr air filter crossover?
 

Anyone know what air filters will fit an 07 450fsr? I looked at the parts crossover but it doesn't state what gas gas bikes the parts fit

I think you will find it is the same as the 05 and 06 which is the circa 2000 Honda Cr250 filter. You will probably be able to verify it using the search facility on this site.

I have a 2006 450 and that's the same filter as the 2 strokes if that helps.

I don't know what air filter cross checks with the 07.
I have an 07 and it is way different than the 03 450 I had and the and 04 300 I still own.
BTW the 03 450 and 04 300 share the the CR 250r air filter.

there is no cross over, the 07 filter changed from 06, you can use a CR 250 dust filter which adds a bit more protection but is not a perfect fit, so its Standard or nothing.

According to Twinair's website the filter did change in 07. The 07 onwards part number is 158046FR which incorporates a laminated layer of backfire retardant foam. Prior to that the part number is 158056. Summit racing quote prices of $36.95 and $28.95 (ouch!) respectively. I think I will take good care of the 1 I have from now on!
