| Jasper, don't give up on riding a sportsbike again.
I've had some serious stuff done to both mine and although it takes ages before you can even scratch your head, you will recover eventually.
Unfortunately it's an age thing, in that the older you get, the longer it takes.
I was back on the ZZR after about 3 months and although the riding position is not as forward as an SP, it did weigh about 4 tons ( or so it felt)
...for gawd sake don't drop it though, cos you'll never pick it up again!
Good luck and stick with the exercises ! |
