Honda Ruckus CVT

[m1rchegfn]

how many KW is this bike stock ?

[videofan080]

do you have to shift or does it do it auto cuz ima git a gokart and it has cvt trans and i dont like manual trans so how do u opperate stick shift or jus let it do wat its doin

[sabadashi]

the CVT is automatic. Although you won't feel any jerking motion when the car shift gears. Technically CVT doesn't have gears. It uses belt that's why you won't feel any jerking motion.

[mvz1991]

its an automatic gear system

my aerox has the same and it does 70 mp/h and its a scooter

[monstercameron]

that cvt is sexy

[panzarw]

Lets say an Arial atom would have a cvt, the speed from 0 to 60 would be not 2.9 but faster.

This type of gearbox is to wearable, the belt is the weak point also the heat from the friction.

PS why they dont use disk CVT ?

[drz4000]

It sounds like an electric motor? Or is it just that quiet?

[AgentK001]

It's that quiet. It's a 4 stroke 50cc engine.

[MonolithTyriss]

The drive is never 'decoupled'. The Variator turns with the engine. As the speed goes up, the springs on the vari can go out, putting more pressure against the belt. More pressure on that end, means a tighter grip on the clutch. Once the belt grips the clutch tight enough, it's springs get pushed -in-, and thus grip becomes applied to the axle and thus the wheel. Slow down, the pressure is lost on the clutch, and it can no longer grab the axle.

[AgentK001]

The drive does decouple. You can clearly see the clutch bell not moving at the beginning, and end of the video. The clutch bell (round thing with 6 holes) is connected to the rear wheel via reduction gears. There are no springs in the variator, only on the clutch shoes, which are inside the clutch bell, similar to a drum brake setup.

[MonolithTyriss]

Ah. So do the clutch shoes actually function as the rear brake then? Or is there a seperate setup at the rear wheel for that? If the reduc. gears are connected to the clutch bell, what is the drive belt actually engaging at the clutch end?

I guess I'll need a real explanation of how the clutch on the Ruckus works, this new information destroys my theory, now I don't know how it's able to engage and disengage like that!

[LMF5000]

@MonolithTyriss It uses a centrifugal clutch. When the engine revs above a certain speed, the clutch engages. When the engine RPM falls below a certain value, the clutch disengages. Look it up on wikipedia, or even videos on youtube will show exactly how one works.

You still need a normal rear brake, even though engine braking happens in the same way it would on a normal automatic or manual transmission.

[manunggal]

@AgentK001 true, the clutch tech on CVT bikes is old one, even my auntie Honda C70 from 70ish had that clutch, two style emerged, the bearing style and the shoes style ( came up later ). My Suzuki has the bearing style tho.

[justi960]

holy crap thats cool whoever thought of this either has no life or is really smart

[gijs01061993]

WOW THATS AMAIZING

[DrummerMan52]

what would happen if you accelerated, then let the back wheel down, stopping it?

[Nailgun96]

The Earth would implode.

[Laofse]

He would break his scooter.

[RR2K7]

You would lurch forward and make a small screech with your back wheel. Pop and lame wheelie and then continue as normal.

[AgentK001]

That's exactly what it does.

[roycehellion]

a 50cc will not do a wheelie, esp with it in overdrive as it was approaching, not enough torque

[AgentK001]

It will if you sit back far enough.

[roycehellion]

.. and weigh enough. then your not really doing a wheeli, your just leaning it back and letting the engine keep you from falling on your ass. even my Big Ruckus will not wheelie with the CV tranny, but yes you can reproduce a wheelie

[elmexicandehoustone]

@AgentK001 yep he's right!

i have a 400CC kawasaki, man is that thing heavy!

it also has a CVT because it's an automatic(gay, lol)

but it's pretty neat at the same time, well, it has like two belts or cluctches or wtvr because it has a low and high side, so i put it in low the other day and floorboard it and as soon as i do that, i lean with the flow of inertia/momentum, whatever you want to call it, and i pop a wheelie!

[Charles2337]

Wow thats how it works!? Thats awesome.

[TeamYankee2]

How is the drive de-coupled from the wheel at low revs ?

[Andalite789]

the belt tenion at low rpms is nothing when it revs and the "SMALLER" puley pins faster it grabs the "biger" puley

[AgentK001]

Wrong. It's done with a centrifugal clutch.

[NAPALMJUNKY]

I live in Australia and we dont get the ruckus over here, what a shame I really like em. You reckon the local Honda dealer could import them...

[Neuroelectronic]

Awesome, is that the stock transmission? plz reply directly, thnx.

[AgentK001]

Yes.

[dub85lin]

so THATS how that shit works! I learned something from YOUTUBE!

[landyacht06]

snowmobiles and 4 wheelers have this too. also go-karts

[skogpekka]

Excellent demo!

[penalozaur]

Indeed.

[zoomer46]

that shows in 20 secs,what normally takes 2hrs to explain to someone.
