foot peg vibrations?

Thought I'd ask the 919 Collective for an answer. I searched "919 Vibrations" and didn't see anything pop up on title.

Right at 5K RPM, I'm getting more vibrations on the left peg and pillion peg than I am on the right. I'm not too concerned but I'd like to fix it if I can. The pegs are OEM. I'll check the threads are secure but didn't know if anyone else had this problem.

Newbie 919 owner and put about 500miles so far on the 07.

Thanks.

I had the same vibes, more like a faint thumping than a vibration for me, I have 4k on the clock now and it's gone. Try lubing the chain, I think it may have been that.

at about 5k sounds right. one thing you can do is swap out your sprockets. put on a 17t front and 44t rear. will drop your freeway rpms a bit. i'll get to 80 mph and be just shy of 5k rpm.

another thing you can do is take off the rearsets, go to a hardware store and find some rubber seals to put between the rearsets and the lower frame to help dampen vibrations.

Probably wouldn't be a bad idea to grab a service manual & a good torque wrench to make sure all is good to go. I usually do this with new bikes just for peace of mind.

---- A good pair of motorcycle boots can do wonders for vibration in the pegs.....and I have rigid mounted rear-sets.

Thanks for the suggestions. I forgot to note, I bought it w/ 7800 miles already on it.

I'll lube the chain first and go from there.

I never noticed how buzzy the pegs were, until I put antivibration technology in the handlebars. WOW...the pegs are buzzy! Good call on the chain/sprockets!

+1 on the turque wrench. And just a silly question, but have you had any other bikes? After owning a 77 HD, the 9er is smooth as pie to me, but it's more a point of view i think. I lost one of my bar end weights and just took the other one off, i don't notice the "buzz".

I had a idea about this in a previous post - the left peg does vibrate on the 9er at certain revs - if you removed the entire holder and rubber mounted it behind the bolts with a couple of say rubber washers bolted it back up I suspect it may be a lot better.

I've not tried it yet as 5k on the open road is way over the NZ speed limit (60mph) so I'm not there for long and when in the hills it is not noticed as I run past it!

Also maybe experiment with loading the left footpeg with some weight - it would be relatively easy to sort out some form of lead holder bolted to the underside.

Yeah I guess I should have mentioned that too. Riding for 10yrs everything from a K75C to my current ride in the garage alongside the 9er -Burgman 650 Scoot.

I rode my buddies old Panhead and wow, I think I lost a filling.

This is my first Honda and my first naked bike. I thought I might have some vibes through the bars but not so much. I have a Renthal touring bar on there now I think (came with the bike)

It's not a deal breaker but I find at 5K I'm around 80 and I seem to be running that on the highway quite a bit. The only other thing that bothers me is that the FI is a bit twitchy at low speeds. Other than those two things, the bike is a sleeper that runs like a scalded dog when you twist the wrist.

Taking the pegs off and putting some rubber washers on will probably fix it too. We'll see if I have time this weekend to look at it. Today and tomoorow are good riding days here in DFW. Gonna be too chilly Sunday.

Check and make sure the exhaust mount weld underneath isn't cracked too. Some have experienced that and got some pretty good vibes. Good luck!

hey sharkey, if ur gonna do alot of freeway riding, or spend considerable time near 80 mph, change your sprockets, TRUST ME! you can thank me later. change the front to 17t and rear to 44t. you wont lose much in the way of acceleration (hardly noticible), but man it makes this bike a real sleeper on the highway at 80 and then run like a raped ape when you whack the throttle.

If you think your 919 is vibey/buzzy, you aren't riding hard enough.

Plan to take care of that Thurs Afternoon with a decent ride south of the metroplex. Weather should be nice. 29 was just too cold for me to hop on it to head to work this morning.

I may have found a way to reduce the vibrations in the left foot peg. I get a bad buzz in my left foot peg at around 4500 rom. None in the right. I did a Google search " Honda left foot peg vibration". I found out that the early Honda VFR got a bad vibe in the left foot peg at around 6000 rpm. It would seem that Honda tried to reduce these vibrations by adding a weight to only the left foot peg, on the 2000 models. Time to experiment. Looking at images online the 2000 VFR footpeg looks similar to the 919 footpeg. So I figured one would fit. I found one from a wrecker. It just turned up. The weight is substantial and is rubber mounted underneath the foot peg. It fitted to the 919, only had to swap the peg feeler over. I haven't had a chance to test it on the bike yet since it's been raining, maybe today. Wish me luck.

Had several good hard rides now. Vibration is definitely reduced but still there. Also the range of revs the vibrations felt bad at has been shortened. Before it felt intense from 4500 to just below 5000rpm. Now it pretty much comes and goes at 4500. That's the biggest difference the VFR footpeg has made. Reduced the duration of the bad peg vibes. I'm going to remove the rubber washer I placed behind the rear set mounts and see if that makes a difference. Also going to go back to the OEM16t front sprocket, it has a rubber damper around it, and see also if there is a difference.
For now I'll just avoid sitting at a constant 4500rpm, and keep the VFR footpeg on.

Buck up! My 848 has skinny little aluminum footpegs, bolted right to the frame. No rubber to be found. It's a motorcycle. It's noisy, smelly, and vibrates, just the way God intended.

Check your exhaust hanger for the infamous crack. Probably have it.

The exhaust hanger is intact on my bike. I did think it might be the exhaust that was causing the bad buzz. I'm running loud cans. But it's only in my left peg?
Maybe the JT front sprocket I'm running. Or it's just the way my bike is.

Islandboy, Since you are still in the trial and error phase you might consider adding even more weight to the left VFR footpeg - maybe doubling what Honda did with their VFR production solution. I'd bet that will further improve the solution. A short piece of angle iron might do the trick as a test.
The OEM front sprocket with the rubber bumpers no question help reduce chain noise. I really noticed the difference with the 17 tooth aftermarket sprocket I tried for a while. But I don't think this will have any effect on the peg vibration.
Very interesting thread!

I completely got rid of the bad vibe in my left foot peg. A few nights ago when tinkering on the foot peg I noticed if I gave the rearset a good wack with the heel of my hand I could feel/see/hear a vibe near the passenger peg. So I removed the pegs, vibe still there. Next I completely removed the weight at the end, vibe gone. Went for a good hard ride today and that bad buzz in the left peg at 4500rpm has almost completely gone. What a pleasure to ride, pegs smooth all the way.
I was under the impression that those weights at the end of the rearsets were there to damper out excessive vibrations. Well they made things worse in my case. I wonder if age, 15+yrs, has hardened/shrunk the rubber mounts? Everything felt tight. Nothing loose. Dunno.
Maybe the vibes were engineered into the rearsets. I remember reading a press release that stated that Honda had a crack at making the 919 "feel" vibey at a certain range. To give the rider some feedback. They just didn't get it quite right. Something like that. I'll see if I can find it.
For now vibes are pretty much gone. Passenger pegs will remain off as well as the rearset weights. I will keep the VFR footpeg on. Maybe tinker with the weight?
Yeah sprocket probably had nothing to do with it.
Also am seriously considering a set of Sato rearsets.

This is the article I was talking about, in regards to the vibrations. About halfway.
I'm not sure if it's a load of crap or not.
