DeepSeaBiker: My friend complains of pins and needles and numb wrists from riding his 2005 GSX-R600 and he is thinking about selling his bike because of this.
jaffa90: It could be the wrong angle on his clutch/brake levers, if they are OK it sounds like too much downward pressure on his arms (tell me about it).So a more upright position is needed try a 650/1250 Suzuki Bandit.
bryfor59: I don¹t know what age your friend is, but I was in a similar situation. I rode sports bikes for a lot of years but latterly I was getting pins and needles, sore wrists, cramp in my legs etc etc, I put it down to knocking on a bit.
Anyway, I reluctantly sold my R1 and got myself a GSX1400. I can get to where I am going now with nothing more than a numb bum,
Irwin: I think if you buy a good pair of gloves with lots of padding in, instead of these race gloves, you might get past it. I get pins and needles as well, and that¹s with being on the Bandit. Mind you, it could be my age, I am over 50.
zak03: Pins and needles is caused by poor circulation. I suspect every sports rider gets this after, say one hour. It may help if you change to a more upright position, but before then try to keep moving fingers every 10 minutes.
Paul49: Get a Meriden Bonnie, do a few thousand miles then get back on the GSX-R600. Problem gone!
eatcs01: Tell your "friend" to try bar risers, thicker gloves, and even heated grips. Has he replaced his original bar end weights with lighter aftermarket ones?
They are supposed to be heavy, so they damp out any vibrations. This would be my FIRST question.
Then, are the chain and sprockets in good condition and properly adjusted?
This can cause vibrations. How about wheel balance?
flatspots: Loosen your grip on the bars a little. The bulk of the pressure should be on palms.
Try to take some of your upper body weight off your forearms/wrists with improved posture. Your back/stomach muscles need to work a little harder.
