Hi 72tx340,
The company you are talking about is known to "stretch the truth" a lot.
Whizzer USA does not offer a motorbike kit period! Let me say this again WHIZZER USA DOES NOT OFFER a motorbike kit.
One of their past vendors has made efforts to unload a bunch of left over junk, and I feel sorry for anyone that makes the mistake of buying the trash.
I am talking pure junk! The cylinders are junk, the head overheats, the bearings fail, the lifters are defective, they pump oil [better own an oil well], etc.
If anyone buys one, get ready to send me lots of money to upgrade them [approx $500.00]. Buy one for $850.00 add $500.00 to make workable equals $1350.00, what a deal!
Have fun,
