pah! get yourself a zx-10R..

I've had mine to 172mph off the limiter... in 4th gear!

They hit the 186mph speed limiter in 5th (before the rev limiter) and you've got another gear to go. Christ knows what they read de-limited.

I know bike speedo's massively overread though before anyone starts

There's a video on dumpalink of a guy hitting the 186mph speed limiter in 5th on a zx-10r too
