What's the buzz...

[quietguy_imp]

I am one who finds the CB buzzy, and in a way that disagrees with me more than I wish. A high pitched but fairly powerful vibration, tingling, begins at around 3500 rpm, and worsens through 5500 until it settles down. Felt in the bars and pegs, Particularly bad in the seat and tank, and it really doesn't agree with my gentleman's region.

I know how to get by it, by short shifting, which I do not enjoy as a riding style. One can make the excuse that 'it's not meant to be wound out, it's not that kind of bike' but that's an excuse I don't buy...it's a modern, 1100cc new design from the ground up, and it's a Honda. I can compare vibrational effects of the V twin, vertical twin and Triple motors, as I own them all, and none of my other bikes bother me anywhere near how the CB does.

I imagine that aftermarket exhaust, seat, flyscreen, etc might contribute, but I've done those mods to other bikes with no such effect.

I know it's a personal thing, bikes shake, rattle and roll, and everyone's results will vary, but that's my experience. Please don't take this as a point of argument, I'm not demeaning the CB...it's just a report based on my ownership.

I always believed there were "factory freaks" where certain engines make more horsepower, use less fuel, or run smoother. I suppose if you believe in this, it works the other way where you might have a less powerful, thirstier, or more vibey engine. It could also have something to do with how well the entire bike is bolted together. Given Honda's reputation for quality, this might be a harder to believe theory.

You mention the aftermarket parts and I think that might contribute. I have heard that the extra weight of a factory exhaust helps to dampen buzz and vibration. I didn't notice a difference on my Staintune, but out exhaust cans are rubber mounted.

Ultimately, it comes down to individual tolerances and preferences.

I would have to agree... And I think this would apply to most all motorcycles.

Next time you feel the buzz, see if it changes with variations in road surface. One of my bikes has become unusually sensitive to road conditions. I'm hoping a change in tire brands will mitigate this.

Compared to my VFR800, my 2014 DLX has a lot more vibration through the seat at highway speeds.

Has anyone on the forum done a balance shaft adjustment on their CB. When I was on the ST1300 forum, some had complained of excessive buzz and cured the problem by adjusting the balance shaft.

Didn't Honda induce a vibration and NOISE when they made their big twin to "compete" with HD? Maybe they carried the vibration over into the CB design and forgot - LOL.

Mine, at least, will buzz pretty badly at 5k RPM, through the bars and pegs. Luckily 75mph is 4k RPM in 5th. I forget where it subsides, but it does go away. I think 6k.
