Question
  • Q. Will this fit straight in a non rolling nut engine?
  • A.

    You would need to use a cylinder spacer with the 54mm crank. These here are a straight fit.

  • Q. Mine is 52mm, 105mm(standard). It's possible to fit this one?
  • A.

    You can fit these cranks in replacement of the 52mm one. But because they are longer stroke you would also need a base packer plate. It will be best suited to the 172cc cylinder kits.
