Posts: 13	S40 Engine Counter-balancer Information Needed 10/22/09 at 12:43:17 Greetings: Can anybody tell me if suzuki has changed the counter-balancer (S40) in the engine in the last couple of years. I've read somewhere that they might have refined it a little in the 2009 model? TRUE/FICTION?? thanks Kevin

Don't know about '09.

Thanks Mr Hyde: Grin

The reason I ask- is that I have heard that the vibrations from the single at highway speed on the S40 is pretty bad. But, if they have since made improvements on the counter-balancer from 2007 and up, this might not be true anymore.

Any comments on highway speed vibrations on later S40s' that would be great.

Thanks
Kevin

I have an 05. If I had a windshield I might be more aware of vibration at speed, but as is Im so busy hanging on Im not all that aware of it being "oppressive" or too intrusive. Its not an inline 4 cylinder Honda, fershure, but its not what I call Bad. Now, if I hold the throttle too tight, the hand will go all tingly. I like the way it makes my feet feel on the pegs. Maybe thats why the tank is small, so people have a reason to take a break pretty often? Maybe thats why the seat sux, to keep people focused on something else?
Its been in production a long time. If it was too bad, well, you know..
OHH, & you can fill the handlebars with lead shot, too.

I don't know about the other riders on this site, but I tend to listen to my bikes and ride where they are happiest. At 60, my 03 is happiest in 4th gear. It may not be the best for gas mileage, but the engine is running smoothly and feels like it has a lot to give. In 5th, that sweet spot is at 70, but I notice that my oil consumption goes up above 65, so I don't tend to ride there unless I am in a hurry to get somewhere, which is almost never any more. I do not notice any appreciable vibration, in the saddle, the foot pegs, or the handlebars, when the bike is running in the sweet spot.

I not only brought it up, I brought it out. And, I did it much faster than any of you have.

Hmmmmm.... I always thought that going down the higway at 60 in fifth seems like th engine could use a 6th gear. Doing it in fouth for any lenght of time .... Huh

Kevininsc,
The vibrations that you feel with the S40 are different from high reving engines. At least that is the case with my '06 S40. Some engines produce a high frequency vibration while the S40 seems to produce a lower frequency vibration. I have had other bikes put parts of my anatomy to sleep, but not the S40. You will feel the single cylinder fireing pulses, but they are mild and even pleasant. There are some higher pitch vibs, but I have not found them objectional.

As to the S40 making body parts tingle, those bikes must have muffler mods or are driven at extra high speeds.

When I bought this S40, I aked the seller about vibration. He compared it to a riding lawn mower. However, I don't think lawn mower when riding my S40 Boulevard.

I believe, if you get a good S40 without much engine wear and is running right, you will be very pleased with the amount and type vibration it produces. It is a motorcycle and feels like one, It has a fairly large displacement of 652ccs, so some pulsing and vibration is to be expected.

These are only my observations on the bike in question. I suggest you find someone with an S40 and give it a ride since you are not sure about the vibrations. Good luck......Dan
