The Cobra and Vita Uno are very similar bikes and use the SWX type motor,many find this motor ideal for their use(see Lancslass). The BPM is a larger diameter with improved low speed torque,it is used on the Tornado,Typhoon,Escape,Arriba.Thanks Dave, I will call you next week, I have noted the vita uno seems the same bike too.... Is the bpm motor only on the two you mention ? What is the diffrence on the cobra motor ? Cheers
Trust that answers your question.
KudosDave
