cbr400rr

Hi i´m from Costa Rica, i hope to get usefull information from here in the future. Right now i´m trying to raise some money to buy a a cbr400 from 1987. Actually, if someone could tell me the differences between the 400rr, the hurricane, and other denominations from 1987 it would be really helpful!!

I've been riding my 50cc bike for 6 months and wish to upgrade to a more powerful bike. I know 2 other guys who have recently bought CBR400RRs and I've taken a short ride on the back of a CB400. I'm deciding which is a more reasonable bike for me to upgrade to, if to upgrade to at all. I ride...
