People 50 reduction gear/final drive/gearbox/ETC PROGRESS
« on: December 30, 2019, 01:08:09 PM »
Sadly, no one makes traditional "aftermarket" reduction gear ratios for the People 50.
~however~
You know who does make multiple gear ratios that fit? Kymco does.

The gearbox used on the People50 2t, Kymco used/uses for other models as well. So I've been tracking down those models, and counting teeth. Then re-counting teeth. Putting a photo into paint, marking each too, and each 10'th tooth. Recounting again.... I hate counting teeth.

Turns out, they aren't just using larger variators to get higher gearing, but different gearing ratios as well....not just by models though, but by model year too.
The People 50 it self, I've found to have 3 separate gearing ratios among the model years!

The hard part is that there is no part number, or model make number, difference between bike years using these differing ratios. So you'd just get what you get if you'd order a OEM stock part.
The gears also share the same part number regardless of bike model, and only differentiate by referring to the bike model it self. I imagine there is internal S/N sorting or something that Kymco uses, but it's not anything you can use to order parts with.

It currently looks like the best way to get the least reduction, would be to split/combine the counter shaft from two separate models.

1998 kymco people 50 15 to 68 to 15 to ? the one with gaps
? Kymco people 50 common 15 to 59 to 15 to 61
2001 Kymco People 150 ? to ? to 17 to 61 <-split this guy right here
Chaz35's Kymco People 50 15 x 58, secondary 15 x 57 (I think he miss counted)

Someone please find the People S 200 gearing! It uses the same gearbox as well, and has the most displacement out of any that do.
A lot of Kymco 16" 150's use the design of gearbox as well, but it hasn't been easy finding good info on theirs.
The 300's and 500 exciting use different gearboxes from what I can tell.

If anyone could measure from the center of the driven shaft, to the counter shaft center- that'd be great.

Pictures! Pictures.....got those...
