I CURRENTLY OWN TWO H2 BIKES . A 72 AND 73 THE 73 IS IN RESTORATION MODE.THE 72 RUNS BUT SINCE I OWN NEWER BIKES I HARDLEY EVER GET TO RIDE IT. I BOUGHT THE 72 IN 1980 AND RODE IT IN SO CALIFORNIS FOR 5 YEARS. IT WAS SLIGHTLY QUICKER THAN A KAWI 900 (MINE HAS CHAMBERS) I STILL LOVE IT AND WILL NOT PART WITH THEM.. MOST (IF NOT ALL) PEOPLE UNDER 40 YRS OLD HAVE NEVER HEARD OF THEM ......TOO BAD FOR THEM!!!!!!!!!!!!
