I'm looking for some opinions from riders that went from a f3 to a newer bike (f4i or rr).I'm happy with my f3 and the mods I have done. I took the looks that I like from the f4,rr and added it to my f3. now I'm stuck. do I want to put more money into the bike (real good tire,some motor mods) or should i look into a newer bike?
