Sprocket size

Discussion in 'Bling and Appearance' started by cacookie72, Sep 17, 2006.

  1. I've bought a 1990 TT250 road/trail that has a top speed of about 80km/h. Can anyone tell me what size sprockets it should be running. It's O.K at the moment for trail rides but would like a bit more speed on the road.
    Thanks Cookie

  2. Does it top out because of a rev limiter? If so, you can afford to use a smaller rear sprocket.

    If it tops out because it's not powerful enough - ie. it'll go 20kmh quicker if you're pointed down a hill with a tailwind - then you're pretty much stuffed, sprocket size won't help you achieve higher top speeds.
  3. I can get 90 out of it going down hill. Not bad ahh.
  4. Mine goes 120kp/h.
    Maybe yours needs a service, or maybe... Are you 7ft tall?
