For the first few minutes of our 6yr old on her Yamaha PW50 we used one of those recoiling dog leads and the bike de-tuned a touch. Going along at a fast walking pace in front of us is actually a good way to see if they have got the 'use the throttle (off) *then* the brake' idea.
She then moved onto a Yamaha TY80, then Piaggio Skipper 125 > Wuyang
125 for her test and then an old MZ 250 for work and general running about. Yesterday she was carving an Easter Island type face into the stump of a tree (she and her b/f felled for my cousin) using her Stihl saws.Maybe if we got her a 2/ car she'd be more interested in taking her car bleedin test!
Back onto cars and ignition-kill ccts, I've ordered a couple of the cheap Cobra touch key immobiliser's with the intention of fitting one to our old Astra (along with some visible protection) and another to the Hi-Lux laddo has just bought and about to drive back to Scotland (for his tree surgery / firewood business).
