They've got one of the actual bikes used in the show at the Cars Of The Stars Museum in Keswick, though I'm not sure if it's listed on their website; http://www.carsofthestars.com/cots.html
I've been to the museum a couple of times whilst visiting the Lake District. I don't know if it's because I'm grown-up now, but the motorbike looks small in real life...
i never had one of those, i seem to remember getting an AirWolf helicopter that had a truck inside and there was a trigger on the helicopter, once pulled, it released the truck, if anyone knows what i'm on about please say something!
