Modern Vespa

Inline spare wheel carrier for a px125 without removing the tool box?

Or is there a mod I can do on the toolbox?

Will doing this get you home? You already have a spare on the bike.

i dont have a spare currently due to a left hand exhaust

Many left had exhausts can still carry a spare wheel, with some careful adjustment.

Tubeless rims, no need for spare…

i know but i want an inline spare

But i want an inline spare if i can dp it

You could massively mod your tool box. Cut out the center and make two very small tool boxes on each side of the tire. Might be difficult to get a tire in and out of. It would be a ton of work but it could be done.

It would be unique for sure. Would it be worth it? That's up to you. I won't tell you to do something else.

thats what i was thinking or getting a toolbox fabricated around the wheel for ease of removal wasnt sure if it had been done before

I've seen an inline tire carrier that was mounted on a smallframe that had a legshield glovebox modified to fit.

Use one of these (they do become available from time to time) -

Get rid of your existing toolbox, and use one of these - https://www.sip-scootershop.com/en/product/spare-wheel-holder-pascoli-for-10-rim-closed-floor-board-lengthwise-for-vespa-gs150-vs2-5t_90956000?cr=7e3fb874-954b-4f28-924b-72d215e4c463
