Yet An Other St4...

Discussion in 'Builds & Projects' started by JouniK, Oct 1, 2023.

  1. Hello!
    I purchased my ST4 just to build a cafe racer. I started yesterday, the riding season here in Finland is about to end (for me, at least :D )

    After/today: IMG_9177.JPG

    I really would like to use some other swingarm. I know the S4R Monster arm fits, but are there any other (single sided?) arms that fit? Modifying the arm/frame is not a problem, but I would like to go with the least amount of work :D
    Thanks!

  5. Hmm at first I was thinking about using Radical Ducati tail, but now I’m not sure.. I think the traditional cafe racer tail looks better. IMG_9223.jpeg
     
  6. I love these conversions/rebuild threads. Makes me think about doing one but I have enough projects waiting in the wings.
     
  7. Things to do:
    Air box/pod filter?
    Stuffing all the electronics somewhere
    Swingarm, how about modifying the suspension mounts to get more option?

  8. Some progress: The tank and front fairing are mounted, frame mods are almost done as is the rear subframe.. I´ve been thinking where to put the electrics and the battery. And the swingarm definately needs something.. :D
