NCY transmission kit

[scooter steve]

Hi I fitted the NYC super transmission kit and a new belt the acceleration has improved but the top speed of 65mph remains any ideas guys I was expecting a little faster

[scooter steve]

Oh it's a 2013 UK spec 125 esp

Did you change the rollers and drive face? I replaced my rollers with 13 gm rollers. I haven't changed out the drive face yet. What was the top speed before you changed everything out? You can't expect too much of a change from a little scooter. I have a 150 cc vs your 125 cc. As I understand it on mine, changing the variator, drive face, and rollers will give me perhaps 10 mph increase in top end. That is about it unless you do something drastic to it.

I changed everything in the super transmission kit variator rollers drive face 13g weights clutch and bell and spring all so honda drive belt acceleration is a lot better just same top speed

That kit wasn't so super was it... here is what you needed for 78 mph on stock rubber, with the 13 gram rollers, I didn't like the 12's https://www.youtube.com/watch?v=-NRc9g3Dasw

That's what I have fitted so here is the killer question how can I get 70 mph + I all so fitted the clutch

If you have the items in the video, you can't install rollers incorrectly into that setup and if your belt is the proper one that only leaves the clutch. I have never replaced the clutch on PCX so I have no idea if that is were you are losing the speed. With a stock clutch and those NYC items and the right belt you should easily get 70+ mph with the 2013's even with oversized tires. Is your speedo wacked? Use your phones GPS to see actual speed. Is your RPM what it should be?

The clutch is fitted correct as it can pull little wheel spins lol the Speedo is good as it worked before and after the only thing it can be is belt I fitted a new honda belt but there is allways the possibility i the wrong belt I.e part number I kept my old belt I'm going to put it on tomorrow and road test my tyres are standard size

Hope that's gets you up to speed... your 2013 is faster than my 2015 given all parts are the same. I installed the NYC products you see in the vid but kept the stock clutch and belt. I can just get to 70 on a good downhill BECAUSE I have the biggest tires you can fit on stock PCX rims. I could fly if I put the spindly IRC's back on but 68 is fast enough for me https://www.youtube.com/watch?v=5EQ6MHoIYAo

wait you have a 125cc ?

Is it the correct belt? If it was slightly small it would not reach the top of the pulley.
It's worth checking but probably a long shot.

[scooter steve]

I'm thinking it's the wrong belt as I got it of ebay now what is the part number of all of the belts because I thought I ordered the correct size I know there are three sizes dependant on year I fitted the correct year size

[Alibally]

Have you still got the old belt? If it's in reasonable condition refit it and see what speed you get. Is the part number still readable on it if you have it?

[Alibally]

The part number I get is
23100-KZR-601

That's for a 2013 WW125D

Check the chassis number to verify this.

[scooter steve]

Yep that's the belt I fitted just measured against old belt there the same size

[homie]

now I'm curious how that aftermarket clutch is dragging the anchor... whats your plan?

[scooter steve]

I stripped it down today it all looked ok but the clutch bell face was a bit iffy not smooth so I am going to 're fit original clutch and spring and take it from there oh the joys of scooter tinkerage

[Alibally]

Does it hit the rev limiter or just run out of puff?

[scooter steve]

Just runs out of puff will hit 83 on the stand rev limits kicks in at 72 down a big hill

[homie]

I think that will do it... whilst we wait for the refit I've done a little tooling on the vespa, hows it look? She will do 160 on the flats
