need to find a cheap 125cc bike for new starter

my girlfirend is just starting to get into bikes and we are looking for a 125-cc motorcycle (not scooter) for her to get some experience on before going from cbt to full bike.

if anyone out there can be of assistance in pointing in the right direction to a good bargain, i am willing to do some work so long as its cost effective then drop me a pm please, not fussed by brand, style or milage at the moment, all offer welcome please.

My nephew is hoping to upgrade his CBR 125 - 3000 miles on hit.

I think he is after £1700 - but I told him £1500 was more realistic.
