No older than that, the very first generation of off road minbikes in the late 70's. Pretty gutless but a lot of fun.Let me guess a YZ80?
Again, goes to prove my point, a YZ80 is a purpose built race machine, mum should've done her due diligence to check the 'mini bike' first. It's not the fault of the bike it's the fault of the operator.
It's not the fault of pride in ones nation, it's the fault of w***** who uses it for ill will.
