How to install a mountain bike stem/handlebars on a PCX.
First of all take off this thingy. If you don't know how to take this off, I would not recommend you try this mod.

Drill/hollow out the top of the mount like this.

Now chop the steerer tube off your favorite mountain bike, like this.

Next, find the appropriate tubing/pipe/shims etc to join the 2 steerer tubes together.
I was thinking about using a 1/2 drive 18mm socket but,
I used part of a steerer tube from a gy6 scooter.

So chop and lightly grind the threads down on the gy6 tube, too fit the mountain bike tube.
Fits perfect with a good press or hammer...

Now, weld the 2 tubes together like so. If your ghetto drill a hole through the pipes and put in a bolt and nut
(probably not as strong but should work in theory).

Moving on, put your new shaft into the thingy. For extra security I drilled a small hole in the thingy for a pin.

Now weld in the pin and weld the parts together like this.

So now put your shaft thingy back on the PCX, and decide how high or low you want your bars,
by simply moving the stem up and down.(ape hangers anyone)

Cut your new steerer tube to the desired height(don't cut too much or you will have to start over)...
install a "star nut" or weld in a small nut inside the steerer tube, I welded in the star nut.

Now put everything back together and enjoy a very comfy riding position.

(I would recommend a short DH stem or BMX stem).

So why did you do this? Is it to have handlebars a little further away from you? You can just tilt the stock bars fwd you know. And remove the seat hump so you can sit further back.

Whatever floats you boat. Don't see why you would want to bastardise a perfectly good bike.

All in the name of rider comfort...

I like a low seat, stretched arm position.
I just can't stand the handlebar in the lap position(like most scooters).
But, mainly most "motorcycle handlebars" (I tried a couple different ones) have a wider center(too wide overall) and more pull-back/sweep than I like.

Can you get a picture from somewhere further out? It's hard to see what you did.

Also, mind if I move this to General? How-to is for common tasks or helpful guides. This is interesting, but probably a one-time thing, I doubt anyone else here is daring enough to replace their steering stem.

If you think it is better in general

you can move it.
