| Being new to s/wings i would like some information.The problem is that when i start off there seems to be some grumblings and vibration around the front end which dissapears once you have started moving,also vibration on hard acceleration,could it be that it's just how the twin cylinder engine is and that it's normal for this type of scooter.My 125 yamaha Majesty single cylinder and 1200 vmax v four are both smoother.Any information would be appreciated. |

Age of the bike? Had it serviced recently? MOT?
I have only limited experience on my scoot too, but it is a smooth ride I find, not as smooth as a 4 cyl will give you, but good enough. |

Very common on the stock Swing. The root cause of the problem is the gearing of the engine through the front variator. Gearing change on the front variator occurs too quickly, resulting in the engine running below its torque peak. This results in loading the engine at too low an rpm, resulting in shuddering and shaking.
There are 3 common remedies to raise engine rpm on initial takeoff and acceleration:
1) Use lighter rollers in the front variator
2) use more efficient sliders in the front variator
3) replace the front variator altogether with a J. Costa variator

| First it does not hurt anything.
I demo rode the SilverWing that I bought----the shaking up to about 35 mph bothered me at first----then, so what, Hondas do not break very often. Has warranty.
May have gotten smoother as the miles piled up.
I have had 8 rubber band drive scooters---Drive Line on SilverWing shakes most.
TMAX was smoother but much more complicated mechanically. I think 250 cc is about tops for this type of drive line to work well-----My 125 (new) Daelim in Korea was smooth, took a lot of abuse----in spite of heavy city and commercial use belt trouble on scooters there is very uncommon.
John Grinsel I generally do not modify bikes as Honda is smarter then I am on their own products. |

I tend to disagree. If they were so smart, why didn't they install HyperPro type springs as standard equipment?
You can't tell me that the stock springs are safer than the HyperPro's (less brake dive, more precise cornering). |

Honda, and all the other manufactures, fully support the efforts of aftermarket engineering.

| I remember the DAF cars----which were kind of a joke. DAF trucks, big ones, are all over Europe, I am unaware they have rubber band drive, and if they do probably much more complicated than the SilverWing simple system.
In context of scooters, once a again I say, based on experience, 250 seems to work best for this kind of application------both Yamaha TMAX and Suzuki 650 Burgman have more complicated applications, the TMAX actually has 2 clutch system, one wet, one dry. I put 11,000 quick miles on my TMAX and got rid of, seeing expensive maint. down the line. My 400 Burgman was also not exactly smooth in power application---and they had series of clutch troubles......maybe brought on by unknowing owners.
Having wasted lots of money over the years trying to modify stuff that didn't seem to work right----I now find it cheaper simply to buy something else and get the experience-----So far Helix has been best rubberband drive scooter with the built in trunk and easy to change drive belt----buffeting just as bad as other scooters.
