Should be fine as long as you have the right bolt bushings, I have a set of shorty 412 s on the shelf for a Hardley, I sent them off to Progressive for a cautionary rehab, $35, that's when I found out. They sent 'em back with the right bushings as well. Also Progr. verbally assured me they would work fine on our Triumphs. BTW, I see 412 s on sale at that price quite often. I picked up a set of new chrome 12" baloney cuts last month on FleaBay, $210.00 plus ship.
