Vibration

Just wondering if any other C50 owners get a vibration in the floorboards after you hit 70 mph? WE NEED THAT EXTRA GEAR!!! ha ha:Fflushed:
 
nope... my o5' C50 gets a bit gutless around 85 or 90...but I have had it over 100 on flats... and I know the engine is working hard...but no particular vibration in the floorboards.....
 
I've noticed it but more due to RPM's than straight out MPH. Seams to be within a slightly higher than Mid range RPM.
 
Ya, I agree about the extra gear I wish I had one to. My 06 c50t is the very first bike I have had and I love it but I run a little higher RPM's than I would like. It vibrates sometimes and others it dosen't but I love the bike anyway.:cool:
 
I, too, am a new owner of a 2007 C50. At first, I was somewhat put off by the vibes on the interstate. However, I'm now getting used to it and find it's really OK at 80 on the speedo.

YMMV.
 
Believe it or not I found the cheapest fix was inserting some of those gel inserts into my riding boots.

I mean hey...if gel palmed gloves make a difference, why not some gel soles in your shoes. :mrgreen:
 
I'm starting to believe that it really takes a lot of miles to break-in these motors. I also own an 07 C50 [bought new] and it rides smoother at higher mph as the mileage grows.

I have a friend who rides an ST1300 [a honda sport tourer], after he came back from a 7000 kms trip, he said his bike ran much smoother after he passed the 20000 kms on the odo.

What is so great with buying a brand new machine is that you get to experience all these different stages of bike's life and performance. I used to get a bit buzz at 100 kph but nowadays I don't, maybe colder temps keep the oil viscosity thicker and that absorbs some of the vibes, but who knows until I ride the bike again next summer.
 
The vibration in my 2008 C50 starts around 50 mph, by 60 it vibrates my feet off the floorboards, and at 70-75 the entire bike vibrates very bad. The vibration is in the engine, I have found through infrared, vibration analysis, and ultrasound testing that one cylinder runs much different than the other. I think the difference is what is causing the vibration. I am a Reliability Engineer and certified in the above technologies and have used them to detect industrial machine problems for the past five years. I do not profess to knowing much about motorcycle engines, I have owned several different bikes over the past 35 or so years and have never had a problem like this one. I have ridden both inline and V-Twins, my last bike was a 1999 Suzuki Indruder no problems with it, great bike.
Around 70 mph you will not want to stay on the bike more than 5-10 miles, I have taken it to two dealers twice each. One dealer says there is nothing wrong with it, the other says the vibration is present, and it is in the engine however they cannot (or will not) do anything about it, and Suzuki so far has refused to do anything. While I like the bike it is useless to me at this point.

I have the DJ---c90 rear drive on my 07 c50. I can ride at any speed and have no vibration. Ive took a couple of 1100 mile trips with 75mph interstate riding for hours on end and very minimal vibration. And I mean minimal.
 
Allan,

I am not sure if you have read the countless posts on the modified C90 drive, but everyone who has put this on their bike has commented that the vibration has stopped. I would say the gear ratio in the final drive is the problem.

Suzuki still will not do anything about it, but if they would fit the C90 drive to the C50 it will change the performance greatly, but I honestly think people would not upgrade to the C90 as much if they did :(
