Front oversized Rotors


New member
New to this site and to GASGAS as well. I have an 04 450 FSE that I would like to use occasionally for SM. I have found a few places to purchase 17" wheels but I am at a loss as to what do about putting a 300mm plus rotor on the front wheel. Gofasters lists a SM caliper adapter and a SM rotor but I was wondering if these will work with my stock Nissin caliper.A few other mnfg list adaptors but they don't include any info on what rotors to use.

I've read thru most of the posts on this site and have not found any answers to this question so any help would be appreciated.
