What would be a good 125cc bike to start with? I am a complete beginer and no nothing I was thinking of a Honda CBR125r, Aprilia rs 125 or the Yamaha yzf r125. But what are your buys thoughts? (Around £1000 - doesn't have to be brand new)

I would go Aprilia RS 125 for two stroke performance and tuning possibilities, the Yamaha R125 for no thrills four stroke reliability.

This is not really the best forum for such a question, perhaps join L biker (forum) or R125 forum for advice on 125 cc machines.
