A similar thing happened to me on the way home from a Vincent Rally some years ago.
With my wife on the back and a UK Motorcycle Journalist following behind on a new Honda, we were heading towards the Monashee Mountains in British Columbia.
There was a long straight just before we went into the very twisty Monashee Pass section. We were rolling along at about 75 mph when two identical new YAMAHA R1 sportbikes went by very close and full bore at about 175 mph . This is a guess, as that is about the top speed of a pre 2010 R1.
I did not see them coming as the road was otherwise empty and I hadn't looked in the mirror for a minute or so.
It was quite a shock, the air blast as they rocketted by was terrific.
After the nerves calmed down, I thought " Won't be seeing them again, thankfully"
That turned out to be wrong.
I had been having quite a bit of fun with the Vincent on the twisty Monashee section when about 30 miles in, there were the two new R1s wobbling around corners ahead of us.
They saw our loaded down old black bike in their mirrors and immediately sped up, which brought on more R1 wobbling. There were several places were I could have gone around them but it was far more fun to pester them from behind and let then know just how slow they were on cornering, holding us up!
They deserved it as the 175mph close pass could have killed us had things gone wrong.
After many miles of this they finally pulled over as I am sure they were exhausted.
The Honda riding Journo was right there for all of this and he thought it was terribly funny.
