Honda CBR250RR : When I was reading an article about comparing new 2011 CBR250R VS old CBR 250 series in another motorcycles website, I was surprised that the 1990 Honda CBR250RR better performance then the latest CBR 250 series (2011 edition). We all know that Honda CBR is one of Honda's superior product, but there is a question which it came out from my head, why Honda has created new products like this? but finally I understand, 250cc motorcycle is not for speed lover and this bike special for beginner rider that needs light weight motorcycles. So I guess, if you need more performance motorcycles from Honda CBR family you can buy used 1990 Honda CBR250RR or go to 2011 Honda CBR600RR, but if you don't care about speed, New CBR250R is enough for you. Here we go the 1990 Honda CBR250RR that I'm talking about.
