Will a 86 atc 250r swing arm fit a on a 86 trx250r???
thank you!!!! very muchAbsolutely. It's the same swingarm... The 85atc swinger will also work on the 86trx but you have to use the 85 caliper/mount & brake stay & one or more of the linkage bolts is a different size but I don't remember which one so I think you have to use the 85 linkage as well but I'm not 100% sure on that.
