sorry to hear that mate. there really are complete tw*ts.
they probably didnt steel the b40 becuase they are much easier to trace as they may have been registered and they are rare??? so if if someone was to see it then you would defo go for a second look. so thats prob why they didnt steel the b40
i am sooooo sorry to hear that m8
yes i agree if he is getting good then he should get a 125cc because he can then enter into compotitions. i have ridden a 125 before and they are great fun but it may take a while to get used to the diffrence in power.
