Vibes

After riding an hour or so at 60-65 the vibes from the motor tend to make my right hand go numb and even tend to affect a leg at times. What do you all do or where to reduce the fatigue from the vibes?

The stock steel bar does not help. The thicker wall of an aluminum bar seems to be better. Or you can check these out: http://www.barsnake.com/ .

Do you wear a backpack? That was the only time I had my arm go numb...from it not being adjusted right.

*OK, i'm of no help. never had that problem.

Yes, however I have the same issue when not wearing. I figured the vibes where just part of a single, but I thought I would ask.

I went with Renthal bars, added some ProGrip anti-vibration grips, and a Throttle Rocker.

Yeah, I get the same trouble - like a tingly sensation to BOTH hands. Right hand I guess maybe from vibes coming through the throttle cable(??); I broke my left hand 8 years ago, & this gets really stiff & aches after an hour or so riding , especially if its cold. Maybe aluminium bars are the answer - I've tried thicker gloves, so don't think changing to a softer grip would help. I haven't noticed vibes through my legs, but my butt....... Also, my right leg gets really hot from where the exhaust heats the frame.

Hey, how's the weather in London? It has been overcast and cold here in California 30 miles east of San Franciso. I makes morning rides to work worse - numb hands, leg, + cold hands, legs, and face. But, it all fun.

I've read good things about Grip Puppies:

My WRR has similar symptoms, it exhibits engine vibrations at an indicated 94-104 KPH in 6th gear. It's there too in 5th but at a lower indicated speed, so definitely engine RPM related. My solution so far is to either shift or stay away from those road speeds where the vibration is strongest (decelerate or accelerate out of it).

OMG, mine must be really sweet or I am used to vibes ... mine seems really smooth especially compared to other thumpers, but even some multi-cylinder bikes. Maybe try changing your wrist angle or different gloves have different padding positions and thicknesses ???

Heatwave!!!!! 31 C yesterday (90 F), 27 C today. No rain for quite a while. In fact, its been the driest start to a year since the twenties(!!!)
My X is getting sticky gears - I think its a combination of hot weather & oil that is getting tired & not high enough quality

I had issues here too
did the aluminum rental bars
better grips
anti vibration gloves from a work clothing store
installed a set of vibronators
I've been useing some vibronators and I love'em
I've had several long rides 4-7 hours 2-3 tanks of gas and no problem my riding buddies have big BMW adventure bikes

on a side note, by next week I hope to have 5x covered bridge photos all in easy ridding distance

had a new BMW GS 800 out on the demo and day and my hands were asleep in 30 minutes.

I have minor issues with the vibronators off off-road but that is my issue not the producets

What size vibronators do you use for Fatbars if you want to use handguards that bolt into the end of the bars?

sorry I'm not a sales man.
I called Don on at the # on there web site and got things squared away.

He's an inspiring guy to talk to.

I use the TexasCycle technique by changing my grip in two ways.

1) Raise and/or lower your elbows

2) Concentrate on varying the pressure points on your hands from thumb-pointing to the middle-to-pinkie.

...probably not a wise idea for some, but at times I will actually hold the throttle with my left and hand and shake my throttle hand out until the blood recirculates.

Note that it happens on every one of my bikes (sport, dual, off-road, SuMo) some with/without AL bars and independent of speed and vibration. ...and I have some real shhhhaaaaaaakkkkkkerrrrssss.

Get a Throttle Rocker. Cheap cheap cheap, and relieves hand fatigue.

You wanna talk vibration? Try riding a 1982 R65LS for 5 hours straight X_x

Yep bad vibes can suck,ride my tt500 on the short track sometime. Now to get yourself a new pair of gloves by olympic with the gel palm. I use them on all extended rides on all my bikes.

I bought these gell knobby grips that helped me. Stock grips stunk and yes my hands were numb after a 45 minute drive. Also try not and grab handle bars extra tight so to speak. That work for me.

This is tough as some of the street rides to and from work are 'white knuckle' rides here in California - crazy-ass drivers.

In the KLR website, several found the BB mod to be more effective than a bar snake or bar end weights.

Keeping with the light bike theme, I did not fill my WRX's bars all the way up. Instead, plugged both ends about 10" in, then filled the ends of the bars with standard old Crosman BB's. Plugged again on the outboard ends so I can get my handguard adapters in and out without spilling bb's...

Maybe owing to the extra wall thickness of my 7/8" aluminum bars, I didn't get as many BB's in there so not as much vibe reduction as I had on my KLR with steel bars. Still, maybe a good 20% reduction. And cheap... did I mention cheap?

Throttle rocker, for sure helped. Then, I just now picked up some street bike foam grips. I forced these thick puppies on over the Dualsport 714's using ProGrip superglue. Now I have nice thick grips. The foam maybe only reduced the vibes a bit, but the larger diameter grips helps with my large hands.

I also use the Olympia gel gloves and like 'em though I find I have to order a size or two larger than real world to get them to fit.

I can go 3 hours easily with no numbness now. As Xracer says, I also need to focus on moving my hands around... and frequently double check to make sure I'm not throwin' a death grip on the bars.

I'm going to try a bit of anti-vibe farkling -

RoxRiser - antivibes
ProGrip 714
Alloy Renthall fatbar

Should provide a good deal of reduction.

Take a look at the Oury Road grips, too. They do a better job of soaking up the vibes, in my opinion, and are extremely comfortable to grip. I've got grip heaters, so for cold weather I swap to 714's; the Oury's are too slow to let the heat come thru.
