    71 Rupp Spitfire

    Also got the 420 chain on, aluminum throttle tube and bar ends in, just looking for a cast aluminum pull start assembly at this point, maybe some more tweaking on the forks.

    71 Rupp Spitfire

    Hi folks, Been on the site for a bit, decided I’d share my bike. Started life as a 71 Rupp frame, forks and swing arm. Dubbed the “Spitfire” because it would backfire pretty good with the first muffler so from there the name stuck. We do a lot of ice racing in the winter so I needed something...

    FLAT TRACK BIKE

    I made some steel extensions for mine, about 3” longer. Work well but I really like the look of this setup. Might have to weld up a long swingarm!

    FLAT TRACK BIKE

    I’m very curious on the swing arm, did you Chop up and lengthen it with other Rupp swing arms? Also loving the forks. If you don’t mind me asking, what’s your gearing?
