## how to tell if a moby is 20 25 30mph

what is the easiest way to tell the difference by looking?

## Re: how to tell if a moby is 20 25 30mph

on the fork stem plate.

after model number

A=30

B=25

C=20

at least thats what folks say.

most importantly if it has a Variator clutch that is good.

no variator and you should buy a different moped.

the variator is THE thing that makes mobies good.

what's the noticeable difference between clutches?

## Re: how to tell if a moby is 20 25 30mph

when did the A B C system change?

didn't it reverse at some point?

## Re: how to tell if a moby is 20 25 30mph

variator clutches continuously change the gear ratio based upon how fast they are moving.

faster low end, faster high end, and no clunky "gear" changes.

gotcha, i've got a 79 50v model c, but it only hits about 21mph, i'm trying to find out if it's a 20 mph maxed out or a underpowered 30 mph?

the post are all a little confusing, some say abc=30 25 20. some say abc=20 25 30... with a reversal at some point.

thanks guys

c model is the 20 mph

Well, there was a switch in 1980. Pre 78 it just said the speed on the plate, 78-79 A=30 B=25 C=20, and post 79 it was C=30 B=25 A=20.

It's on the second page (not dialup friendly).

looks like i have a 20... what are my options for making this a 30 mph? is it just the jug? that really sucks, the guy i bought it from listed it as a 30 mph and i didn't know better... any feedback is appreciated. right now, it's still totally stock, but i do have a 15.15 to put on it, just waiting for the short intake to arrive, should be early this week, i replaced the plug, exhaust and tires. the bikes in great shape, i just want at least 30 out of it, 21 isn't gonna cut it on the streets here...

what about the e g j and m jugs huh?

## Re: how to tell if a moby is 20 25 30mph

is it just a jug swap to bring up the speed?

## Re: how to tell if a moby is 20 25 30mph

No no far more: Carb, elbow, jug and cogs. And the swinging action is what makes them glide
