Suspension
A few weeks or so after the service I went for a reasonably long ride. The next day as I was getting out of bed the muscles at the lower end of my back just lost it. I was off work for a week!
What happened?
Who knows, but I suspect that the rear suspension setting was set too hard and the constant jarring just got to me.
Chris from BM Motorcycles told me the suspension setting should be a lot harder for a bloke 'my size'. Made sense to me at that the time as he wound up the stifness, but I suspect that my back thinks otherwise.
I've wound the setting back twice now ( three steps each time) so far and the ride is back to comfortable again. Hopefully no more back problems.
Yes the rear end will move more and possibly bottom out, but I think I prefer that to my back hurting.
