ok... hayabusa... it has a name, ninja, it has a name, jap bikes, jap names. cool cool i understand. an r1 is 1000cc, an r6 is 600cc. makes sense to me. in the car world it's logical most times; for example a bmw 318i is a 3 series with a 1.8litre motor, that's injected. etc etc etc. with car models, it's simply a case of pick a letter, then pick one after it that sounds ok, (i wouldn't have called a commofore a VD, or a Falcon a BJ either :grin: so in terms of bikes like gsx-r, rgv, yzf, zzr, zxr etc does it have meaning?? is it just random bike company lettering or anything?? or is there a theme, for example, a kawasaki might have 1z for sports, 2 for sports tourers and stuff?? or no, just random??
