Not today, exactly, but the other day.
I fitted some tank grips for my knees.
I found that I was getting white finger, mostly on the throttle hand, but sometimes both.
I found this was relieved by sitting back and not leaning on the bars so much.
I fitted the grips and now I am gripping the tank with my knees more and this supports my back in keeping my weight off the bars.
Worked a treat and now it feels more comfortable.
Not going to work for everyone, but just thought I'd share as I know a few have had comfort issues before.
