I don't think I've had a bike scare me (yet), but the circumstances have.
I was with a couple of buddies who were on their 600's and I was on my 'Busa riding through the countryside.
The 'Busa is a nice bike, but definitely not as agile as a 600 through tight twisties.
Well my buddies had built up a sizable lead on me through the turns, but once the road opened up I decided to go into hyper drive on the 'Busa an catch up.
So I had the throttles opened up quite a bit and was going about 160 MPH when the road showed a left hand kink I was familiar with.
So I slowed down a bit to make the kink and as I rounded the kink I noticed that my buddy in the rear had slowed down dramatically (around 40 MPH).
I knew I couldn't slow down in time, so I said a silent prayer that no one was coming in the opposite lane (not too much traffic in the country) and kept left and passed my buddy at about 140 MPH, scaring the hell out him in the process.
I rolled out of the throttles to about 120 when at the next kink my other buddy was doing likewise (like WTF?).
So I passed him on left at about 120 MPH while I was coasting down.
That's my story and I'm sticking to it!
