I am riding this bike more and more but my right hand goes numb pretty quickly. I am sure my hand has some carpal tunnel issues because this happens on my other bikes too but not as quickly or as much.
My question is has anyone done anything to relieve some handlebar vibration in their X1 or similar ride? I can't do bar end stuff because I got my mirrors there.
Any ideas? I was thinking about the one inch risers with some rubber mount between??
Thoughts??

My entire bike vibrates a ton.

Easy stuff first:
Primary chain tightness
Muffler and associated exhaust hardware tight?
Pop off the front flyscreen and look for signs that something could be buzzing in there with rub marks.

It doesn't take much to amplify the vibes in a bike that already vibrates pretty well.

Harder stuff:
front isolator perhaps.

Did you put in new isolators when you did your rebuild? They would be a lot stiffer than the old ones you took out.

Yes everything is new. Maybe I will get different grips.

You'll think I'm nuts (which I kinda am).
Fill your bars with BB's.

I have used the fat hard rubber grips for years. The stock narrow grips make me clench my hand into a fist. I find the 'clenched fist' position to be extremely stressful.
the fat grips keep my hand open enough not to overlap, it also allows me to keep a relaxed, looser grip.

Use your core muscles and a relaxed grip on the bars.

The bigger grips feel more natural to me too. I don't know why

You don't say if its shaking at speed, or at a stop. If at a stop, turn the idle speed to 900-950 rpm.
I'm assuming you mean while on the road. It shouldn't vibrate very much at all once you're moving, over 3300 rpm or so. If is is, probably first check like Natexlh1000 said.

As said before there should be hardly any vibration at the bars at highway speeds. I have some vibration at idle but I just loosen my grip and it doesn't bother me. And I have the most recent version of the front isolator. First check to make sure the vibration varies with the engine speed and not anything else. Do you wear gloves? You may feel more vibes if you ride bare handed.

I use these grips and they seem to help a bit. When my hand does get tired, I just grab the large rubber flange to isolate my hand from the bars.

Mark, it may just be that you're getting old like me, my hands go numb no matter what bike I'm riding mostly from problems with spinal compression & shoulders due to half a lifetime driving trucks.

As others have said a relaxed grip will help & fatter grips too. I have more trouble in the cold weather due to winter gloves & the need to grip harder.

Next bike will have hand guards & heated grips for sure.

Jramsey's solution works for me.

Using my core to hold my body in position allows me to avoid stressing my hands from hanging on.

My hands are relaxed with almost no pressure unless I am initiating a turn.

I learned this one years ago riding my Triumph twins.

The vibration would quickly numb my hands if I held the bars tightly but I could ride almost indefinitely if I just loosened my grip.

WOW lots of information. Thanks guys. I also ride a 30 year old Shovelhead so no stranger to vibration. I was thinking bigger thicker grips as well, but I measured the bars yesterday and they are 7/8" but the throttle is 1" so I don't know if I need to see who makes this pairing. I think the bars are aftermarket.
It mostly vibrates all the time not severe just well I am getting old and used so I am just looking for a bit more comfort. I did get gloves yesterday with a little padding and that seems to help a little. I think if I raise the bars an inch with American sportbike riser and get fatter grips I should be ok. If not I may try the bar snake thing.
I would try the bbs thing but my luck they would spill out and I would run them over and fall down. 8-0 Thanks again guys.

7/8" bars and a throttle side measuring an inch would be the case always, unless they shrunk one side of the bars to miraculously make the throttle side also 7/8". Plain old 7/8 grips will fit.

Some anti-vibration bar ends will help your situation, as will some plushier grips.

I switched to lower bars and the vibration was cut dramatically. Also the different riding position seemed to help get rid of "dead hand".

If you want a wide range of grips, go to your friendly neighborhood japbike dealership.
Another option is grip puppies.

Bar end weights helped on my M2. I also wear a set of slightly padded gloves and that was a huge improvement.
