They are forged . I only need one .I dont remember how many I threw away when I bought XS 650 bikes, just to raid the engines for racing . I thought somebody might have one of those raided frames sitting around doing nothing . Normally I am not a stickler for 100% purity , but this bike I had for 20 years and I would like to bring it back original in new condition as a weekend bike. ( The H2 just drinks too much
) . The part number is IT3-27420-00. The bike is D model 1976.
