Sled: 1973 SR 643 B


From: Michigan

  Modifications: 1973 SR 643 B. This is original condition and unrestored as is the SSR. The skis ( Rupp magnum ) and carbs. ( 44 mic. round slides ) are the only parts not stock.  The SR's came in 3 size engines: SR 292 one cyl.  SR 433 twin, SR 643 twin, from what I'm told Yamaha made around 100 of each

 We at Totallyamaha thank Chris  for sending us information on his sled and hope he will keep checking back with us for more excellent info and more features.
