Does a Nolan N 43 Trilogy Large Fit under the seat of LX150?

Nope. I don't think there is a full faced helmet that will fit under the seat of an LX. However, if it has D rings you can attach it to the hook under the seat to keep it safe while you're away.

Thanks! I really like that helmet and used to have one while I lived in Bermuda but didn't have a Vespa then... I am still a little unsure if i would want to attach it with the D ring when I park on the streets of NYC.

The trilogy doesn't have d-rings.

It is such a cool helmet just leave it on and go about your business

Haha!

Try taking the chin bar off.

Mine does

I'm sorry, but I have had several helmets that fit (albeit tightly) in the LX seat bucket. One was a full face Arai in a medium size. My Schuberth C3 in a large also went in there, but you had to press down slightly on the seat to close it.

The trilogy is quite a small form factor helmet so it might just be on of the helmets that fit. A reasonable shop should let you try it, as well as letting you try it on your head!

No need to be sorry, that's potentially good news for the OP. I have never been able to fit any ff helmet even in the larger GT200 bucket, so I assumed the LX bucket would be even smaller.

I hope it works for the OP.

Thanks all, I think I am going to stop by a shop that has them and see if it will fit.

Will post here once I tried it and know the answer.

I guess the "D" stands for down under.

Have had LX scooter (sold earlier this year) and N43 helmet, it will not fit under the seat, but it will fit in the Vespa-branded topbox for an LX (barely, you have to orient it just right, but once you learn the position it is easy to close/lock the topbox lid with the N43 inside)

edit: my N43 (that wont fit in underseat bucket, but did fit in LX topbox) is a medium, not a large (as the OP asked about)
