I saw a couple of lads with a teensy weensy trail bike up on the heath the other day......TBH unless you have a car park or a local go kart track that will allow you on, I can't see the use or attraction of one of those minimoto sports bikes...but a mini trail bike.....woooooot!!!
It was small enough to strap on instead of a pannier to take to thinks like the hog raost (sic) ....what a bloomin laugh that's be if several of us turned up with them!!!
