141mph on the speedo - 129mph on the satnav with more to go.
...On the first day, I found unless I tucked in my arms and knees and got my head right down behind my double bubble windscreen, the bike was oscillating like mad from 120mph to 130mph!!!... and if I sat up under braking it got worse!!! :eek :eek
Previously I remember the bike being more stable, although that had been with a top box and panniers and prior to replacing the head bearings and servicing the forks. The steering is now really light and maybe the fork service changed the geometry a little?! who knows..? I'm also a bit heavier these days?!
So the following morning I did a tyre pressure check and put a little more in front and rear to get 38/42. It made it a bit better to ride so I decided to power through and found I could reduce the oscillation a little if I put in a slight steering input.
So the results...
When I tucked in, I got the needle past 140mph on the speedo and it was still pulling!!... However I looked down at the TomTom and that was showing just 129mph. This was all fast enough for me and not a speed I wanted to sustain, so I backed off. I would say on a sustained run the bike would hit an 'actual'/satnav speed of 135mph.
Is a sat nav more reliable than a speedo though?
As you say, and as i found too, it's not a desirable thing to ride at these speeds. The extra thinking and attention that is needed, looking way ahead for any lane changers, is hard work, as is the wind on your body, and bike.
It is something you need to do though just to get it out of your system.
Anyway, do i get a prize for saying 140mph?
