| | wondering if it is me or if it is a problem anyone else has? After riding 20 miles or more my hands seem to go to sleep. I have tried not holding on to tight, it is mostly in my right hand. Thought about changing grips but I figured I would ask before I go out and Buy them or any other suggestions anyone would have? |

| there are a few possibilities that come to mind. The bike, your arm, and your fit on the bike.
The bike- does it feel like the bike vibrates a lot, especially at the handlbars? if so, this is a likely culprit for the numbness, and you should contact your service department and see if this is normal for the 250, or if its fixable. this would be a situation where larger, softer grips might help. since it happens more on the right, I'd be a little surprised if this was the only factor, because vibration should affect both bars.
Your arm- you may have tightened muscles, ligaments and other tissues in your wrists, especially the right. when you get onto the bike, you either bend the wrists back slightly, or tense them to keep them from bending back, thus tightening the above structure further and pressing into the space the nerves are traveling through, compressing them, causing numbness and other potential sensation problems. (I'm a Chiropractor, by the way, and see this often.) this is very much like carpal tunnel syndrome, just that it only happens when you put the wrist under added stress. it is also something that many riders deal with at some point. if you are right handed, it makes sense that that side gets it worse because of how much more use it get, especially on a computer/mouse. to help this, stretch the wrists by standing facing a wall, and placing the palms of your hands about shoulder width apart on the wall, with your fingers and thumbs fanned out, then move to a position where the hands are being gently pressed backwards toward you. you should feel some tension and stretching on the bottom side of the wrists and forearms, but don't stretch so far that its actually painful. do this for 1 minute, steady, with no rocking or bouncing (these can cause muscle pulls) at the level of the most stretch without being uncomfortable to the point that you can't make it the whole minute. do this every single day, once for 1 minute, and also do it for 1 minute before each ride. it may take time to see results, 2 week to 2 months, but its worth it.
Your fit on the bike- your body postion on the bike may make it so that you are forced to jam the wrists backwards just due to where the bars are relative to you. if this seems to be the case, try adjusting the brake and clutch levers so they are at the most comfortable angle for you, and consider getting heli-bars or some other product that will alter the geometry involved. If none of that works, you may need to consider a bike that fits better, but that is obviously the last resort.
Do the stretches, and get some aftermarket grips, (ask at your parts department, they should be able to help if you let them know whats going on), and check to see if vib problems are common with the 250.
Defeinitely do the wrist stretches, even if its not the direct cause of this problem, it will prevent future wrist problems and possibly even the development of carpal tunnel. This goes for all riders.

| | Thank you for the reply. It gave me possibliities that I have never considered. there is very mild vibration in the bars, just normal though. I had ridden years ago when I was a kid, but I think years of hard work in my previous job has the bulk of play in this problem and you are probably right. I will deffenently do the hand stretches and try a softer pair of grips. The bike fits me great and I am very comfortable on it so I think you are right. thanks for the help, Chuck |

| The Ninja ZX-RR is Kawasaki's race bike built for the MotoGP world championship. In 2008, it is ridden by John Hopkins and Anthony West. KE 175 used for Kawasaki racing in the international 1985 Kawasaki racing. The ZX-RR has struggled in 2008, with the best result being a 5th place in Portugal from John Hopkins and also from Anthony West in Brno. The bike has frequently lapped at the rear of the pack, and both West and Hopkins have blamed both a lack of feeling in the front end, and traction from the rear on corner exit. Previous ZX-RRs have been very "unfriendly" and difficult to ride, but beyond the limited statements by the riders it is unclear what the problems with the 2008 bike are.
