The Honda PCX / Forza / ADV150 / SH Forums

On Jul 9 I installed Dr Pullley sliders, 11 gram, into the variator of my 2013 PCX.

Today, Jul 31, I swapped them back out for the old rollers. The old rollers are in pretty good condition, a slight flat here and there, but still OK. I will replace them in another couple thousand miles.

After replacing rollers I took the old girl out for a test. I liked the sound better than with the sliders--somehow with sliders engine noise had been more obtrusive. I liked the acceleration too--I don't think the sliders did much, if anything in that dimension.

I especially liked the fact that I was able to get up to 60 mph again--with the sliders I couldn't get past 55.

Mpg with the sliders was either unchanged or slightly less than with rollers.

So, for this rider (others, I know, have been luckier), the Dr Pulley experiment has come to an inglorious end. Maybe if I had used heavier sliders things would have been different and better. I don't intend to find that out.

I am going with stock from now on--at least as far as the variator goes.

So, again, sayonara Doc--and, lest I forget, sayonara 30$.

Definitely The weight, not the concept. . Mel helped me get the 13 G Drpulley sliders and they are , one year later, still performing very well, with the top and speed up somewhere in the high 60s. I wanted stock hgh end , and more off the light acceleration, and I got it.

Hey Zonky,

If you're not bashful, do you mind telling us your height and weight?
I'm wondering if lighter sliders work for the Clydesdales like me, and the more average sized people don't benefit so much?
Maybe there is a point of diminishing return or a sweet spot for slider weight vs rider+scooter weight.
The only drawback for me with 11g sliders is the scrubbing sound they make when you let off the throttle or hover around a certain middling RPM.

5'7", ~140 lb . The PCX and I have a marriage that was made in heaven..

Ahhh, maybe there is some merit to my theory.
See, you're light enough that the engine probably isn't breaking a sweat to get you up to speed. Whereas me on the other hand...
When you think about it, you're probably the specification the bike was designed around for the Asian market. So it just works for you as is.

I don't know how the sliders did NO AT help you. You would be the ideal for them. Just for the sake of experiment, if you have the funds, try 13 gram...either sliders or rollers. With that gram you should see an increase in acceleration though your top end should stay about the same.

I think the PCX can handle a wide range of types--you at one end and me at the other.

What are the stock rollers? 14? 15?

Supposedly 18g on the OWL, and 15g on the LED. But I'm not sure that 18g is consistent across all markets?

OWL? LED?

2009-2014 = OWL (because the headlights look like an owl face).
2014/2015+ = LED (because the headlights have LEDs in them).

The stock rollers on my 2011 were 15g. I can verify that 13g sliders are good, but the acceleration is better but there's no much change in the top speed. Just a few mph.

My 2013 used 18g rollers, I weighed them on removal at 2k miles. Replaced with 12g sliders and gained 3-4 mph at he top end (68mph) and better acceleration throughout.

Maybe the 125s have 15g rollers regardless of year?

I believe the Far East spec bikes had 18g and everywhere else had 15g. I presume it's because riders are bigger and heavier than the far eastern ones so they made the rollers lighter.

So do you think it was the wrong weight choice?

It may have been--or the configuration of the rollers didn't agree with my PCX--it likes round weights that roll not weights with a point on them that slide.

Can you break this down a little? Unpack it? I mean, what are the mechanical unperpinnings of this argument? How, in other words, do lighter weights benefit heavier riders. I don't say it isn't so, but I don't get the picture just yet.

I'm thinking you might have gone a little light like some of the previous posters
almost identical to you in stature 5'6 and 145 lbs and installed 14 gram sliders
Today I pulled out of a controlled intersection from a dead stop onto a highway with a fairly steep grade
and had no problem of achieving 60 mph quickly and maintaining it
after a couple miles the grade changed to 8% and the bike dragged down to 55 mph or so-still OK
Now coming down was a different story. I was paying more attention to hanging on-but I'm sure I must have been pushing 68 mph plus

Must have had the sliders in upsidedown. They always give more top speed. Not less. Very common mistake.
