Heh, heh, heh, easy? Only if its a Vino/Vino clone, since there's no dash in the way. Ifn you're lucky its just a matter of removing the dash, not as difficult at is sounds, at least on my Kymco, five screws as I recall and a dozen or so snaps to pry apart. Yours maybe slightly different, but I doubt it'll be much different. Oh, and you might need to remove your mirrors, on mine the windshield is mounted to the mirrors, so it had to go, as did the mirrors as the windshield and brackets kept me from separating the sections. I found reassembly a bit harder as the gauges kept trying to slide away as I tried to put the halves back together again.

Javarod is right, you are in for some fun! The speedometer is mounted in the dash panel that is closest to you when you are sitting on the scoot. To get at the speedo, you need to remove all the screws attaching the front and back dash panels together, unsnap the two halves, and sort of peel the panel back and down. This will expose the back of the speedo where the cable attaches, plus a whole bunch of other scooter guts too. Its all do-able and not really hard, but there is a lot of risk of screwing things up if you are not careful. That's what usually happens to me.
Study the dash carefully. Make sure you remove all of the the screws holding the parts together. You'll have to apply some force to get the plastic parts to unsnap, but if you apply too much force the plastic will crack. So be careful, if you find you have to apply a lot of force, back off and make sure you understand exactly what is holding the parts together (maybe there's still a screw left in.) Watch out for the little clips. Mine usually fall off and land in some inaccessible cavity, so I have to take off more body panels to fish them out. And when you reinstall the dash, make sure all the wire connections are still good - they have a tendancy to come apart when you pry the dash down. Yup, you are in for some fun.
Before you get in to all of this, I'd suggest a couple of things. First, remove the internal speedo cable fully and inspect it. Make sure its not broken. (Both ends should have 'male' ends with square cross sections.) Simply disassemble the speedometer gear thingy at the front wheel and pull the cable out. Second, if the cable isn't broken, reinstall it and try the scooter again. (I'm thinking that perhaps the problem is that the internal cable isn't seated properly in the speedo.) If you are lucky, maybe just pulling and reinstalling the cable will fix the problem.
And of course there is plan B: The bicycle computer. (Just kidding; the bike computer is a great addition to the chinometer, but I wouldn't consider it a substitute.) Cheers, Gary

Thx Gary....Thats a great idea to pull the cable first..I did disconnect it from the front wheel thingy ..it didn't say anything LOL..anyway i did disconnect but i didn't pull it out..anything is better than ripping apart the dash area..my memory stinks and it'll be a crap shoot to get it back together BTW, can it be the front wheel thingy??

Take the speedo cable of the front "thingy" and spin the wheel (forward), you should see it spinning inside the opening. If it is not easy to see, just pull the inner cable out of the housing some and stick the end back into the "thingy" and try again. Make sure to keep the inner cable from kinking. While spinning the front wheel gently squeeze the inner cable between your fingers, that will tell you whether resistance may stop the "thingy" from proper operation. The inner cable usually has a square end both sides going into a receiver on the "thingy" and speedo, I've seen the receiver on either speedo or "thingy" wear out already, that by the time there is any resistance it doesn't grab properly. Resistance could simply be from the bend of the speedo cable assembly going from the "thingy" to the speedo.
I have even gone as far as clamping the bottom end into a hand drill chuck and gently accelerated the drill to see if the speedo is working, make sure that the inner cable is properly pushed into the speedo receiver and again no kinking.
BTW, what is the proper term for the "thingy"? I know the German word is "Schnecke" (at least on bicycles), which translates to "Snail". I guesss that 's, because it looks like a snails shell.

Thx Andi, good ideas for analysis..I'll try it this weekend..I like the idea of putting the cable in the drill and testing the speedometer itself too. I heard some clicking noises coming from the area of the snail.I just assumed it was the cable but maybe it was the snail itself...
