| Being a new silver wing owner, I wonder if others experience a vibration on takeoff up to say 2500 rpm and then smooths out about 40 ft. from standing still? I have never ridden another and it smooths out all the way up to 90 or so. its not a misfire feeling or anything and it idles smooth. There is no hesitation when throttled up at all. Just thought I would ask, its got about 6k on it is all. Thanks |

| @salehwood:
The Silverwing four-stroke parallel twin is shaky 'by design', since both pistons move up and down 'together', contrary to V-twins or 2-stroke twins.
I can't speak for your SW, but mine does vibrate to some degree, but 'not a lot'. Compared to other 4-stroke twins I've ridden it is relatively mild in vibration. I've seen idling twins move themself around on the center stand... |

| Talking about 'good vibrations': it didn't take me long to find an example of how bad some twins shake your bones. i just had to enter 'SF750' into the search box to find this clip on Youtube:
watch the bike 'reverse' as the guy rev's it up! Now that's what I call vibrations...

| Not engine.
Try running engine up against both brakes for about 10 seconds or so....fixes for awhile. Mine did that, lots of town riding seems to bring it on.
Probably design deficiency of rubber band drive---My 2 Burgman 400's did/do it also
I found, take thing apart, new OEM rollers seems to cure for awhile.
Nothing to worry about. |

| Nothing to be concerned about but it is frustrating given the quality of the rest of the riding experience of the Swing. The vibration is one thing, the noise coming from the front end is something else. The noise is completely unexpected from a quality product. I plan to test a hypothesis that the front fender is one of, or the primary source of the noise. I'm going to remove it and see if and/or how much noise goes away. If the source is the fender, I have plans to stiffen it and/or add weight to dampen and send the harmonic frequency to a point the bike won't reach. |

| To me all the vibration sound is directly related to the shape of the body works. The Swing is incase all around held by screws,nuts and bolts,and has a hollow chamber from the back to the front. The front where the air comes through, buffets the air ,the rear wheel drive and motor vibrates to the front where it meet meets the air and transfer the vibration the only place to the wind screen that can vibrate to the tip of the wind screen. Its like riding on a a big musical instrument,and you cant change the tune. |

| You might try purchasing foam hand grips that go over your stock grips. They go over your existing grips increasing the diameter and eliminate some of the vibration.They are reasonable and easy to install. I would also suggest cleaning out the belt housing and sanding the inside of the clutch drum and shoes. Also lube the bearing (high temp disk brake lube) in the clutch assembly No special tools required. Howard NWSSC |

| Holy crap! Is nobody going to point out the obvious?
Honda installs rollers in the variator that are too heavy. It makes the engine lug, which causes the dash to rumble. Try 24 gram Dr Pulley sliders and your vibrations will be a small fraction of what they are now. If you can find one, install a J Costa variator for the ultimate in smoothness.
SEARCH function is your friend. |

At least the Swing is not a leaker. I had a TX 750 Yamaha (parallel twin, Triumph knock-off) that shook as bad as the 500 single BSA it replaced. Loved both of them. As bad as the Swing shakes, it will NEVER have the lovely Brit twin shakes. IMHO :flower: |
