The Honda PCX / Forza / ADV150 / SH Forums

I just did some research, and it appears that the 2019 is different than the pre-2018 and post 2021 models. So strange. So, if I had to guess, with the 2019 for whatever reason, Honda went with short gearing, but Tall Variator, and on older models like mine, they went with tall gears and shorter Va...

I don't recall top speed stock. I think it was 72MPH. I did some testing yesterday though. Put in the stock vari with the same weights (almost certain they are stock) from the NCY vari I was running. Immediately picked up from 66 to 70MPH top speed. Swapped in the 20x14G NCY rollers, top speed dropp...

I installed the below parts in 2020 and was disappointed with no improvement in top speed. I learned that 2019 has a different gear set than older models which is why I didn't see the improvement that others saw. I have 3300 miles on my scooter now with the original belt and parts but top speed is n...

Please report back if you swap out the gears. I'm curious if it's worth the work.

Would that be the output shaft for the rear pulley? Wouldn't there have to be another corresponding gear that needs changed as well? I've never taken a belt drive machine apart like this.

I appreciate all the feedback. Something must be different with the 2019 and I'm surprised there are not more posts about this. The rollers weighed 17g each so that's more than older models had at 15g. I've read nothing but positive comments on the upgrade by others.

The variator and drive face did not come with a drive boss - I'm using the Honda one. Should it have come with one?

Thats the thing, I do have the outer drive face and no change in top speed if anything it has dropped to ~66mph. This is rev limited top speed too. I thought going too light on the rollers did impact top speed? Maybe the 2019 is different because it should have 15g stock if I'm recalling correctly b...

Hello, I installed an NYC Variator, drive face and 14g rollers in my scoot and saw 0 improvement in top speed and didnt appear to have any better acceleration. I took out the 14g rollers and installed the stock rollers which weighed in at 17 grams. My top speed was unaffected and remained at 66mph h...
