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.

Might I add, a set of Stomp grips help a lot here too.

I'd add that fitting an uprated link to the rear and re-working forks can make the rear higher than std and the front lower. This is what happened to mine, even after fitting Ohlins forks I think the front is still lower than I started out with. Anyways, fitting adjustable clip ons has made the riding position more comfortable. It doesn't seem like much - but after riding Carlos' where the bars are set further back (less wide) and lower than mine - there's a definite benefit to having bars that are wider (Mine are also longer than std by around 30 mm each) & a little less low. They don't need to be angled down quite so steeply. Imagine it - if your bars were super low and you were riding in traffic, etc all day long your back muscles would get tired - right? I don't mean get higher bars so you can put weight on them, just something more comfortable will make the bike more enjoyable for longer periods IMHO.
My guess is Extrapolator will soon be buying some new bars...

I thought I was doing real good exercising while we were on vacation, but it wasn't showing much
