You own a Yamaha BW's / MBK Booster and want to run an Aerox / Nitro engine on it? Chassis expert Easyboost designed this Easyboost Subframe Adapter Sport to make it possible. Now you can realize a hybrid, called Spitro in France, by mounting a horizontal Minarelli engine (Yamaha Aerox / MBK Nitro) on a Yamaha BW's / MBK Booster (models built after and before 2004) or Rocket / Spirit / Spy. This is the SPORT version, a Racing version is also available.

No need for welding or spending a lot of money on a professional conversion, simply use this very convenient subframe adapter. Quick and easy installation in 10 minutes tops.

The subframe is made from electroplated steel for improved resistance against corrosion and is laser-cut; the side jaws are 8mm thick.


  • 8mm subframe jaws, galvanized steel
  • mounting bracket
  • axle
  • spacers
  • small parts for mounting

Note: the carburetor will point towards the front.

NOT road-legal!
