AHRMA.  The American Historic Racing Motorcycle Association.

Used to be referred to as the premier racing association for vintage bikes., and would like to be the new national home for TZ V twin racers.  Check out the 2004 BOT 2 stroke rules.

  AMA Pro, no longer supports 125GP or 250GP motorcycle racing, but if you follow road bike based racing, this is the place to go.

WERA

WERA Vintage is a great alternative to AHRMA - especially if you can't attend meetings all over the country and still want to win a championship.  WERA has a regional model that works for lots of folks.
