just bought a scooter, 0-30 takes about 7 seconds, just looked on you tube and found it should be doing it in about 3 seconds.
its a yamaha cygnus 125.

Is it getting up to full revs quickly from a standing start?


i would say no
#9
0-50km/h 6.3
0-100km/h ---
50-80km/h 9.8 Seconds

so does that mean 0-80 kmh is 0-50 mph
so thats 6.3 + 9.8= 16.1 seconds for 0-50, that doesnt sound right for 125cc scooter. i drove i a 1.1 suzuki that took 17 seconds to get to 60.

as a vespa and lambretta rider 0-30 in 6-7 secs for a 125 scooter sounds slowish to me i'd expect 4-5 secs depending on the weight of the rider and how the scoot is geared up

0-30 in around 6 seconds on a 10bhp scooter sounds about right to me, tbh i'd expect a vespa to take longer than that
then you would be wrong i'm afraid and i've had many i dont care what a manual says first hand knowledge is the key i currently have a px125 which is a geared scoot making acceleration much more controlable and i suspect that the manual would say diff to me but there ya go

Only way it would get up to full revs quickly is on the centre stand
If it did it under load its under geared

Wasn't sure if it was a bad CVT, but after seeing the specs...mobility scooters look like a viable alternative!

Top speed was around 105kph (65mph) although acceleration from 70kph (46mph) was slow enough to warrant keeping freeway trips infrequent. I must mention though that the Cygnus didn’t have any real problem holding 100kph(62mph) speeds once it got there

Could be worst, the px125 only has a top speed of 55mph, mind you i stand to be corrected as that was just info provided by people using calibrated equipment, owners using the BS method may claim a higher top end
no once again your wrong i had mine to 60mph when it was brand new its like the top gear episode where they tested a car that was restrircted to 155mph and it went to over 190 but like i said until you own one you dont know any fool can look up some tech details on the web that doesn't make them or it right

LOL do you really think the speedo is 100% accurate, allowing for the average 10% out you were doing 54mph, yours can't even do the manufacture claimed top speed X)X)X)
Plus why were you going flat out when brand new, would of thought it needed running in for 1000 ish miles, theres some performance gone for a start
Get 60mph recorded on a GPS before you try correcting me again ;)
geesh right ok the run in is 500 miles at 80% revs through the gears , i quote you " they are only the people that calibrate" so if they are 10% all of a sudden when earlier this wasn't mentioned by you then as above says its reasonable to think that a scoot that has a 55mph top speed might infact do £60 mph but as your trying and failing to be smart as you think the 10% only works against instead of for , as i have said i speak from personal experiance over 25 years of owning scooters and have not had to look over the internet to try and sound smart with a few tech details

replaced the air filter, cost £7.50 from the shop, looked on the net and it says the belt should be changed every 10,800 miles, mine has done 10,600 miles. LOL so have booked it up.

Also could need new variator rollers.

Ok, what is most likely the issue is the rollers, you can put heavier rollers in the centrifugal clutch assembly which increases top speed, but slows 0-30 speed. If you were to put lighter rollers then you will get a slight difference in top end, but a better accelleration. What has most likely happened is the last owner has wanted more top speed so has adjusted.

To access this can be a little tricky, open up the cover connecting the wheel to the engine (usually there is a kick start there) - Then the rear pulley needs to be removed and rollers changed. Any motorbike dealer will be able to do this for you relatively cheap.

to be honest not really bothered about a top speed its just acceleration
will the garage mention the rollers when doing the belt (yamaha main dealer)

All this fuss over reaching the national speed limit, or not in this case. Why an inner city scooter needs to go faster than 55 MPH is beyond me. At that speed you can over take on a 50 MPH road, just, and still do plenty to the gallon.

There are reasons for limits.


Whats a national speed limit :| My only limit is my nerve


Wow, it took 25 posts, you've usually mentioned it long before then...

They should do, they may have worn and need replacing.
