i actually have one of those too, it may have the same engine etc. i've upgraded the brakes though, to hydraulics from the standard piece of...wire?
Mine has a different "shell" on it though, it has a Honda Repsol one...it was a few years back, they're actually meant for adults, and mine had 2 gears, but because i was soo small, it just shot straight to 60mph, (i was 35Kg

im 45Kg now...i really miss it, i killed it when i forgot to put the engine oil mix in the petrol, and i just...kind of overheated, luckily enough, the company had to take all the ones they sold back, because of a manafacturing problem, and i got my £200 back

you know, i might actually buy one of these, *goes to google*
