Raced a Hyabusa he backed off at 220kph. The road is straight with no obstructions for 146k. Since neither of us had a GPS we decided to time my second run. I went back to the start of the straight and he called go (on his mobile to my scala headset) and he checked the time as I passed the 146k sign. According to him and timed by a wrist watch I covered 146k in 28 minutes - You can work it out from there!!~
I now have a GPS and I'm heading out again soon so I can get a confirmed speed.
PS Its not the bike that lacks the power its the rider that fears to use it.
