I disagree. Unless the wheel is slipping on the dyno drum, it's still moving at the same rpm at redline on a dyno that it is at redline on the street. Wind is only a limiting factor in how long it takes to get to redline. The bandit 1200 will redline all day on a dyno in top gear but will not on the road because of wind resistance, weight, lack of top end power etc...If his gsxr red lined in top gear on the street it was doing every bit of whatever speed it redlines at on thr dyno.
