Hi all -

I'm installing my Vespa rear crash bars on my 2021 GTS.

I did the same on my 2018 GTS no problems.

I'm not sure what I'm doing wrong but I can't get the bolts on the mounting bar to tighten against the frame. I don't know if they are stripped or if I'm doing something wrong with the locking nuts.

I can't even get them out of the holes now - or to tighten against the frame.

Any tips?[/img]

Very much stripped. Back off the jam nuts and pull down on the bolt heads with pliers while gently turning them out. Don't strip the threaded bracket or you'll be in worse shape. Tighten the new bolts with the jamnuts backed off. Then bring the jamnut against the bracket.

Thanks! I took it all off. Love this forum!!

I contacted Scooterwest - they've been awesome. I think a new mounting bracket is needed. The bolts were screwed from beginning - and the welding was either off or holes drilled wrong on the tube part.

And I would hesitate to call those crash bars, more like paint protectors if some one was to bump the scooter with the car door or something while it is parked.

I will say the ones on wife's GTV did protect it the one time she laid it down while parking on very uneven ground. She was just at the wrong spot and when she went to put her foot down there was nothing within reach.

I had them on my 2018 GTS - was rear-ended and they saved me a ton of damage. So yeah - I think the manufacture description is apt.

The Vespa bodies have a higher degree of tolerance than what most people expect from modern manufacturing, and they crash bars do too. It's not uncommon to need to do a bit of cold press technique to make them fit.
It looks like someone cross threaded a bolt.

aftermarket and factory accessories can vary wildly in production tolerances. often times a bit of brute force is needed.

but here, that's straight up dripped my dude. hopefully it's just the fastener and not the bracket!

I was able to get the stripped bolts out gently pulling and twisting with pliers. I tried replacing with new bolts and they aren't going in. It's almost as if the threads on the holes are somehow screwed up. The bracket doesn't come separate from the crash bars. I've emailed scooterwest, I'm assuming they will replace. They've been great to deal with in all previous experiences.
