very confused by this thread! It turns out the best 125 is a 600!
Nothing wrong with a wee 125 4 stroke trail bike for a commute, dont let them turn your head! Buy one for £1000 or so drive it for 6 months over the winter and if bikes are still for you then sell it for £900 and get the 600 and test etc.
this kind of thing http://www.gumtree.com/p/cars-vans-m...-ovno/90638308
£1000 should pick up a lovely one this time of year, trail bikes are more the kind of thing a rib man needs! Jetskiers like the sporty less comfortable uncomfortable delicate bikes! Get something you can ride up a kerb to avoid the cars!
