The Honda PCX / Forza / ADV150 / SH Forums

[/list]Just opened up the vari and found these 14gr what look to be dr pulley ROLLERS. I though stock were 18g on the 125. It did have 700 miles and 1 previous owner so maybe he changed them? O well in go the 11g dr pulley sliders from my pcx.

I don't know for certain on a 2019 model, but my 2013 models came with 18gr rollers. The 14gr would give it quicker takeoff, though most of us prefer the 13gr. Try the 11gr but I think you will be disappointed. Along with quicker takeoff comes some disadvantages such as when you are in slow traffic it is harder to keep the bike from trying to jump ahead...sort of like a race horse that you try to turn into a walker. You could mix the weights to get 13gr. and try that combo if you don't like the 11gr.

Just an update, tried the 11g dr pulleys but the clutch and belt slip was preventing a quick standing start so ive put some yellow malossi clutch springs and a +2000rpm white malossi contra spring in and it shoots off like a rocket. Now its gained an indicated top end of 3mph(was 82mph now 85mph) but its slow from 70mph where as before it slowed down at 75mph so its gained top end speed but lost a little grunt top end so will give the mixture of the 14g rollers with the 11g dr pulleys and see how that fares. Also the mid range acceleration is also massively improved. Cant believe this is the same engine as the pcx. Theyve certainly worked their magic when designing the forza.
