Ok.. I live in Houston and I purchased this scooter because I love the Vespa Look but I could not afford one.
I bought it at the local dealer and got it assembled and running.
On the way home it was immediately running great, but after a few miles I noticed that the scooter started to dive to the left.. meaning that I had to firmly hold the handlebar and push "right" to keep it straight..
Once I got home I waited for the tires to cool down and I checked the pressure. The front tire was actually low.. easy fix!... I thought.
After a few hours I went for another ride around town. The scooter was going perfect, than after a while.. diving again! same side. I thought the tire was losing pressure.
Got back home, waited to cool down the tire, and checked the pressure. It was perfectly fine....
So... I wonder: what can make the scooter "dive" after a few miles, and not immediately?
The tires look cheap and without brand.. can it be that the sidewall of the tire is so cheap and weak that cannot handle the weight?
I am planning to replace both tires with Pirelli SL26, and check Fork Oil quantity and quality.
Also.. I will check that front tire and rear tire are aligned..
Any other suggestions?
Thanks!

One of my scooters had the brake line routed wrong and was causing tension on on my triple tree and it only became noticeable at high speeds. Not saying it's what is causing your problem, but you may want to give the harness and lines in front a look over to make sure they're not creating tension in your steering mechanism.....

i think this might be your problem... or the opposite. he is tightening, you want to loosen.
your steering is locking up, yes? if so then i suspect the bearing is too tight. if possible i would take it back to the shop you bought it from and see if they will fix for free.
if you decide to do the work yourself it shouldn't be too difficult if you have the right tools. the guy in the vid used a screwdriver and hammer. guess that'll work. lol...

Sounds as if something is heating up after riding for a little while , after whatever is heating its becoming tight , causing the scoot to pull to that side.
Is it slowing you down at all ? I would lossen the front wheel axle slightly. Make sure the front wheel is not loose , but see if you can loosen it up some .
If the axle is too tight , your speedo puck may be heating up and the gears may be tightening on you causing the scoot to pull left. Considering the wheel bearings are somewhat centered more , I would not expect a bad one to pull that much , but it has to be something in the front axle , wheel hub , if it is pulling after heating.
If it were a brake line , I'd expect it all the time , if it was a triple tree bearing , I would not expect it to pull , just be hard to turn .
What I do with both axle nuts " front and rear " is tighten them just enough so the wheel does not move side to side . I use red locktite on the threads so the but does not loosen on me .

Thank you guys for the inputs.
Well.. the steering works well and move freely. I would say it feels normal.
It's difficult to keep the scooter running straight.. the scooter tries to lean left. But not abruptly. Yesterday I noticed that reducing the tire pressure to 1.8-1.5bar, the scooter is much more controllable, but this is not right..
That's why I am now thinking about the curvature of the tire profile.. I wonder if the 3.50 tire is forced in the rim to the point that it gets an awkward curvature at the outside. At 2.2-2.5 bars, the curvature is much more accentuated than it should be.
Well.. I ordered 2 tires 2.75-10 and I will try to see how they fit on the 2.50-10 rim. It's an easy try, and I can always return them if they don't fit. The original tires had to be changed anyway.. who knows where they come from, or what they are made of!
Hopefully this will do the the trick. I will let you know.

Don't forget to change them cheap Chinese style valve stems if that's what your scooter is equipped with.

This happened to me as well, the rear brake line is just long enough to get routed through the shortest path. |

Also, check the front wheel axle, it might be bended or badly assembled.

If you didn't check the tightness of the front wheel axle , I would do that before you change tires . that is , so you know if it was the tires or something in the axle. Its good to change the stock tires even if they are still good . most come with really low quality tires.

I'll just jump in with this thought- does the scooter "pull" after an exact time, or just when you get up to speed?
Check the alignment of the wheels front to back.

Something has to be out of alignment.
If it was a bad bearing on one side of a wheel, or a speedo drive seizing up, it won't make it pull to that side. The wheel wouldn't be affected that way.
Think about it. If you have only one disc, does the bike pull when you hit the brakes? No.
