This was a great group of posts that I pulled from another thread.

When riding down hill and cornering Miguel's handle bar angle is much more comfortable on the wrists, I also notice this when riding back home as we filtered along a lot of slow moving traffic. I ended up getting a little pins and needles in my hands, a little strange as I never felt this riding before.
Hey, Carlos !
Thanks ever so much for posting your thoughts & comments. Your bike is KILLER ! I almost called Simon, after looking at that stunning exhaust !
The reason you're having those symptoms in your hands is because you're putting your upper body weight on your wrists, with the way you are seated on the bike. These are symptoms of Carpal Tunnel Syndrome, as a result of the compression of the Median Nerve, as it passes under the flexor retinaculum sheath at the wrist.
You should grip the fuel tank with your thighs & bend your elbows & keep them parralel to the tank (touch the tank with your elbows to remind you to correct their angle, if needed), & lightly rest your hands on the handlebars. The hands should be used for steering inputs only & not be used to support the weight of your upper body on the bike.
You may use splints at your wrists to immobilize them at night, when you sleep, if it's a problem after a ride, although this is a temporising measure & does not address the cause/mechanism of the injury. Hopefully, with the change in your posture, this problem will be relegated to the past.
Take Care, Carlos.
I neglected to also mention that one should use their abdominal muscles & obliques (muscle), to support the upper body.
One may use different exercises to strengthen the abdominals & obliques to great affect to help support the upper body on a Sportbike.
I'm no workout fanatic by any means. I've had periods in my life where I hit the gym hard for a year or three, I have some workout equipment in my home too.
But you don't need any of that really. If you do bicycle crunches, at least 25 a day, (build up to 100), for three or four days a week, you may find that to be enough to have a strong core and be able to have better endurance on our beloved RC51. Throw in some jump-rope, lunges, and push-ups, and you'll see a huge difference in endurance.
