I had a 99 R1 and even my 98 ZX9 would slaughter it once the R1 hit 120 MPH or so. R1's are horrible top speed sportbikes. Even tucked under its crotch-sized windscreen like a clam in its shell, the drag at 150+ MPH is absolutely horrendous. In nearly 3 years of owning my 99 R1, I never went faster than 156 MPH on it and that's simply unheard of coming from me. I don't think twice about hitting a quick 165 to 170+ MPH speed but not on my R1.
R1's were never meant to be conquerors of top speed. They were designed more for their sleek poser points and silky smooth carburetion which was second to none and made them a joy to ride.
Even so, I still enjoyed my R1 at less than stellar speeds and it was really fun on the back roads and for wheelies. However, I'd take my 01 GSXR1000 over my 99 R1 any day. The gixxer's just plain better in every way except possibly the R1's sleekness factor. I still think the GSXR1000 has a great appearance. Knowing what it can do just makes ya love it!
The R1 was advertised as having the aerodynamic drag of a 250cc bike but that was if it had no rider on its seat. In reality, at high speed with a rider, its aerodynamics felt more like that of a bread-truck! Even cruising the highway at a steady 80 MPH or so for 45 minutes would take its toll on the fun factor.
