It's a '75 H1 triple. 530 chain, and seriously heavy sprockets. It was tempting to throw on the 520 from my bike- my old sprockets didn't actually need changed, and they're much lighter. I can't believe that old engine makes enough power to need a modern chain that heavy. If it didn't have the exhausts in the way, there would be no need for a center stand. A rear race stand works perfectly fine until you get into removing shocks to get to the axle
