find out!! these bikes arent based around top speed but for road racing! they are torquie for out of turn acceleration. but if you must know, the R1 is around 181 or 189. i have gotten mine up to 175, but ran out of road. and my friend just got a 2004 R6 2 days ago. ive only gotten it up to 120, but i believe they get up to around 175-180
