So when I accelerate, sliders stay longer in smaller gear, causing better acceleration, or so I've heard.
What about deceleration? Will sliders remain longer at the top of the variator, go down as fast as rollers, or will they shift into lower gear faster than rollers?

Will sliders remain longer at the top of the variator, go down as fast as rollers, or will they shift into lower gear faster than rollers? With my 5g KOSO sliders and 1.5K torque spring in my 2T...they just 'glide' and there is no braking effect like I got when I used rollers. With rollers the engine provided a bit of braking effect it seemed and with my sliders there is none. It is like pushing your stick shift cars clutch in...you just coast then rely on the brakes to slow or stop you. My sliders don't give..as truckers call it "Jake Braking'...they simply coast. But can't tell you if it is the sliders or 1.5K torque spring that allows me to coast...vice decel from the engines compression and inherent drag..  |

I've got the same on my EVO150, which is why I presumed it was going to be because of the sliders.
It stays in gear longer, as it relies on friction, rather than rolling, to get into smaller gear.
Basically it stays in heavy gear (instead of upshifting, it's like a car remains in 5th gear, all the way 'till the RPM's go lower than a certain amount (eg: 1500 or 2000 RPM).
That's my theory, however I don't have sufficient backup to support this theory.

LOL a 2T coasts regardless of rollers or sliders where a 4T has tranny drag . Sliders are better try a set and see for yourself

Oh, I did not know a 2t scoot does not have a tranny.  |

Has a tranny but not the drag . I only had 2Ts until I bought a TaoTao and noticed how it dragged where my 2Ts would coast just like my Magnum does

My Echarm I almost do not need to use the brakes it decels so much

I know why one scooter may coast better than another and it has nothing to do whether its a 2t or 4t.
The trannies are the same in a 2t scooter or 4t scooter but you may not know that if you never took one apart.
So I would like to hear why you believe a 2T's tranny coast better than a 4T's tranny.

I have taken it apart . If you do not believe me then ride a 2T and learn for yourself as I know it to be true

So it's a recurring problem then?
On my TaoTao ATM50, I think it has rollers, the engine brakes quite well too (the small wheel diameter probably helps out on this too).
On my EVO, which has 13 in wheels, but a smaller profile tire, overall diameter isn't that much more compared to the ATM50, the engine brakes almost nothing.

I do not like to see people put up stuff that is off the wall that is not true that may change someone's mine not to buy or buy something due to the bogus information given.
There is a saying:
Those who do not know, do not know that they do not know.
F.Y.I,
I know why one scooter may coast better than another and it has nothing to do whether its a 2t or 4t tranny.
Just for your information the trannies are the same in a 2t scooter or 4t scooter. They both have CVTs, Variator, Belt that turns the Clutch pulley that when enough centrifigual force is produced the Clutch pads swing out and grab the bell. The Bell in turn, turns the shaft that turns the gears in the very simple tranny that eventually turns your wheel. But if you never have taken it apart and looked at the tranny you would not know how it works and find that the same gearing setup are the same in a 2t or 4t tranny.
XYLON,
You got one part of the reason and there are others but none have anything to do with the tranny. And just to put it in perspective ALL trannys produce some drag but nothing drastic.

Hahaha that is funny . Do you have a 2T scooter or even ridden one ? Makes me laugh to hear you say you know more how my scooter is than I as you have not ridden it . Try ths , go to the top of a steep hill , push off and coast downhill until you get to 20+ MPH then give it throttle . A 4T will kickback then accel where a 2T accels .
Ride a 2T scooter and learn before you argue with some one who knows the whole story . CVTS are the same but the engines are not . I hope you enjoy your crow with BBQ

AH, now your changing your tune from trannys to motors after another member also chimed in and said motor. But again that is only one thing there are more things that determines coasting ability. That poor attempt for an explanation about 20mph going downhill is Pathetic at best. That my unknowing friend has nothing to do with the tranny. You just showed everyone how little you really know about how things work.  I am still waiting for the VIDEO PROVE of your 50mph wheelies and your 150mph 2t runs. But as always and expected you fade away and change the subject and hope nobody remembers that BS. (HOWS THE CROW TASTING SO FAR..  ) Ride a 2T and learn now that is funny, I have had and ridden 2ts, 4ts big and small when you were still in diapers. Alleyoop |

Well, I'm pretty sure that the engine braking has very little to do with the engine, as both my engines are 4t and one does engine brake quite hard, while the other (though 3x bigger displacement), does not even come near to the engine braking capability of the other bike.
I presume this is a CVT issue, and not an engine issue, as the engine braking scoot keeps revs high when decelerating (IMHO a proof that the cvt goes back to the beginning position), while the scoot that engine brakes a lot less, lowers revs a lot (a proof that the cvt stays maximized there).
