The right gaskets for the job

If you have a Big Bore Athena kit installed on your bike, this is the only gasket set you should purchase. It is quite pricey for 2 gaskets, 1 copper exhaust gasket, & a chain tensioner gasket (CRF450X), but that is the price you pay when you go bigger!

I have a 280 Athena kit on my 04 CRF250R. I am having some work done to it and they told me I needed to replace the rings. It's at a Honda shop and this isnt a Honda part. Would these gasket kit be what I need if I need to replace the rings??
