Fitment
  • Yamaha BWS 125cc
  • Yamaha Cygnus X 125cc
Question
  • Q. Will this fit straight onto the Yamaha Cygnus fuel injected model? Would I need to upgrade anything else?
  • A.

    The cylinder will fit straight on but you will need to adjust the fuel mixture. Something like a Malossi Force Master ECU.

  • Q. Will this fit into my Yamaha BWS 125cc just straight in? Or do I have to buy a crankshaft and a head with this?
  • A.

    These can be used with the standard crank and head.
