Please go to Mackie Harley-Davidson and order me an OEM oil filter for a 2010 CBR1000RR. Let us know how you make out.
They can, doesn't mean they will. Snow city cycle and Marine don't deal in Honda, and are more than willing to order the parts and do repairs. Honda doesn't restrict who fixes their bikes. Cyclewerx fixes all bikes...how do they do it...they must have a secret way to get parts from Honda, probably sneak in a steal them from Honda dealers at night.
Anyway, if that shop won't fix your Honda...another will.
