[youtube][/youtube]For those who missed it, the increase in gearing is 12.8% for a 2013 PCX150.
To my mind this is about optimal for the standard engine.
Yes the set replaces 2 gears as shown here:

The speed sensor works off the larger of the two which has 45 teeth vs 44 of the original (hence the additional 2% error on the speedometer).
Uphill performance is not all that relevant here because CVT tuning takes care of that.
I have not re-optimised the CVT yet. It currently pulls at around 7500rpm. I might even leave it as is.
At higher speeds, rpm is 12.8% less than before.
There is more power than before at higher speeds when the variator is maxed out.
This is because now runs closer to peak power rpm.
(Peak power is at 8500rpm and it drops off as the rpm increase towards red line.)
Fuel consumption has to drop with cruising rpm 12.8% lower.
Of course, the odometer will now over-read by 2% which translates to about 0.06L/100km.
I'll let you know how the consumption goes after a few fuel-ups.
