    gs1150 correct gearing

    I bought an 85 GS1150e last fall and finally got a chance to ride it this weekend. At 55 MPH the tach is at a little over 4000 rpm. Does this sound right if the gearing is supposed to be stock?

    That's about right. Stock, 630 gearing is 15/43. If you decide to change to a 530 setup, you need to have at least a 17 in the front as any smaller will hit the swingarm due to the 530 stuff being smaller diameter same for same. Ray.

      I'm pretty sure the stock gearing is 15-42.

        1100 is 15/42, 1150 is 15/43. Ray.

          Ray, I'm not going to argue with you. My 84 ES has the original sprocket on the rear and it is a 42. Then I check my factory Suzuki 1150 ES service manual and it says 42. Then I check the 1984 1150ES owners manual and it says 42. Maybe the "E" model has a 43?

            That may be so Dar as my E has a 43 on it. Ray.
