Just as stated. My throttle hand, feels so freaking numb, after a half hour of riding, it vibrates so much it actually makes my hand fall asleep with pins and needles. Any way to counter this?

Same here. Take your hand off the throttle when possible to do so safely and shake it a little bit. Get the blood flowing and try to relax your hands as much as you can.

When your riding, don't grip the bars so tightly, you should have a relaxed grip. Hold onto the bike by squeezing your legs on the tank, and holding you body up using your torso (abs and back) and keep a very light grip on the bars. Also, the bike is designed to steer it self (go strait) and react to bumps and imperfections in the road, if you hold the grips too tight, you are fighting the bike (and tiring yourself out). It's just like counter steering, it only takes the slightest pressure to turn the bike. At first you'll have to consciously think about this, but after a while you'll do it automatically.

Saw this on web...

"You may also want to consider softer grips for the handlebars, and bar-end weights that can change the frequency of vibration. Finally, there is a product called a "bar snake" that can be inserted inside a tubular handlebar to damp vibration.
Each of these suggestions will have likely only a small effect. But the right combination may significantly reduce (or eliminate) the problem."

I will add that the stock bar ends do ALOT for vibration reduction. I replaced my stock bar ends with the Yoshimura ones and I now get quite a bit of vibration at highway speeds

Was that a typo? " I now get quite a bit of vibration"

And Ghost you said "Mine vibrated a lot till i got about 800 miles on it.. then it really smoothed out. " Thanks for that info I am going to wait until I pass the 800 miles and see if my vibration goes away before I order weighted bar ends. Wonder what set in after 800 miles that caused the vibration to lessen ?

I have the vibration between 5000-5500 in every gear but 6th. I asked around a bit and it seems like its just something that happens. I was getting a little numbness in my thumb. The best solution I've found is to manage the engine speed so I don't spend much time in that range. Also a looser grip helps too. I might look into some mod options later.

There's some good advice in this thread already, but one thing that would help the Ninja 300 is some grip-pads on the side of the tank. This will let you grip the tank, use your core-muscles to support yourself better and relax your grip on the bars. I've noticed that the stock tank is a little narrow for this, so I tend to use my hands more. On my GSX-R, it had a wider tank so it was easier to grip.

So, tank-pads, grip the tank with your knees, use your core muscles more and relax your grip. At the STAR motorcycle school (run by Jason Pridmore), they told us to pretend there are 'baby chicks' between your hands and the grips (yes, baby chicks is redundant but it's funny). :D

another thing to check is wheel balance. hit a pothole at a decent speed and you bend the wheel easily

i remember reading a post a few months ago a guy checked his engine oil , it was low, he topped it up and the vibration thru the handle bars vanished!!! never heard of that one before but thats what the man typed
