Modern Vespa

Hi everyone.

Just recently got my 2023 piaggio BV400 and have been enjoying it. But once I've noticed the bar is not straight now I can never unsee it. When the scooter is going straight on highway, the handle bar is steered about 5 degrees to the right. While it don't affect the function it bothers me. Where should I go about adjusting the handlebars to make it straight and how involved is it?

The only thing I hated about my BV350's was the handle bar covers. The parts diagram shows one bolt to loosen. Ya got a lazy dealer.
If you can hold the wheel between your legs and feel movement or make it strait or the other direction, this will prove it's loose. I'd go back and tell them to put it in writing that there's nothing wrong so you can take legal action if it causes an accident.
If you can't move it. Ask them why their willing to sell sub standard product. Then ether fix it or find a dealer that will do it under warranty

Brace the front wheel (clear of the fender) against the jamb of your garage door. Give the grip a sharp blow. Check for alignment and repeat. This is what your shop will do if you take it in and pay them .75 service hours.

I've try to done this but it's pretty tight and I'm afraid to actually give it a sharp blow. Is it possible to actually bend the bar or strip some compants this way? Or the most I will mess up is a nut coming loose?

It's actually on there pretty tight. I've tried to not force it much with the curb method but it's not budging, of course I'm not using a lot of force since I'm afraid to break something.

Go to the AF1 racing website and look at the parts PDF under steering. You'll see how to loosen the handle bar clamp.
P.S. Welcome to MV.

You can try putting the scooter on the center stand, then stand in front of the scooter with the front tire squeezed between your legs (not the fender, the tire). You don't have to squeeze hard. Then grab on to the grips and pull one of the grips toward you and push the other away from you to get the bars where you want them. Your legs are there to hold the front wheel solid while you try to turn the bars. You won't break anything and the worst that can happen is you knock yourself over on your butt. The BV will just laugh at you.

Personally I'd bang it (judiciously!) against the steering end-stop. Those are pretty damn strong!
