A couple of quick questions for those who have a 2018 DS - what is the size of the two through-frame apertures that I can see in the official DS photos and which would you advise using for through-frame anchoring?

I would like to use one of them to either pass a sleeved chain through to secure the bike to a ground anchor or instead put an Anti-Pinch Pin through and attach the chain that way. Which of the two would you say was more intended as a security feature?

I just realized that I've never documented the through-frame hole or the swingarm hole properly.

This would be the intended destination for documenting them:

The hole changed fitment slightly from I think 2014 to 2015 and there may be another revision but I can check my 2016 model later.

The hole in my frame has an inner tube brace at the center of the hole that my 2014 frame did not.  It is not a good location to store the power cord anymore as it has sharp edges and can cut the cord's rubber sheath. It is hard to make a quick measurement with a ruler, but it looks like the outside of the frame hole is about 2", however the inside tube support is about 1.5" in diameter.

Attached is a photo of the inside of my frame hole.

Brian - my 2018 DS 11kW arrives at the end of today so I will be able to provide photos and measurements of both holes from tomorrow.

My Dealer advised the swing arm hole as the most suitable for a ground chain or anti pinch pin. Again, once I have usable diameter and through depth measurements I will share those here.

[Richard230]

When I received my 2018 S from my dealer, the charging cable was not stored in the bike.  As I was riding off I noticed the salesman running after me waving the charging cord.  I stopped and he gave it to me, which I stuck in my backpack. I guess it will fit in the swing arm hole, but the owner's manual doesn't seem to provide any guidance on the recommended onboard storage of the cable. I use the stock charging cord for charging at home and carry a short 14-gauge cord in my tank bag for charging at friend's homes where they will always have an extension cord hanging around.

Thank you but I wasn't asking about charging cable storage - this query was about using a ground anchor and chain or anti-pinch pin for physical security of the bike.

I guess I just don't think about things like that.  I have never chained any of my motorcycles to a ground anchor in 56 years of riding.  My security solution is to use a motorcycle cover to keep people from wondering if it is worth stealing. 

I just checked the size of the swing arm hole and it is about 2-3/4 inches in diameter.

The swingarm hole is more than large enough to put the heaviest of chains through. Just make sure that it is sleeved to precent paint chipping.

I have the bike in front of me now so tomorrow I will take measurements and photos so we can capture the information for the wiki.

I've updated the unofficial manual to record this:

I used to put a long Abus chain through the hole in the swingarm and through de belt/wheel.

But it just was to inconvenient and heavy. Now only disclock.

You really have to be careful with those disc locks. If you forget it is there and try to ride off without removing it, you might damage your disc and/or caliper and your bike will likely fall over when it comes to a halt very quickly. Also, if someone tries to move your bike with the disc lock installed they might drop the bike, too.  I think a chain might be the safer way to secure your Zero.

[DanielCoffey]

Most disk locks come with a curly "don't forget" cable that goes from the lock to the handlebar to help prevent you moving off accidentally.

They are fine for a short term out at the shops visual deterrent (you can get motion alarm ones too) but my bike will be in an detached garage so I will use the ground anchor for home and keeping the disk lock for away form home.

Anyway, I will measure the swing arm aperture in size and width then ask the ground anchor guys whether they would use a chain or pin through it. Give me a couple of days to do that.

[DanielCoffey]

Right, as promised, here are the dimensions of the Swing Arm through hole on a 2018 DS...

Side to side : 68mm
Top to bottom : 75mm
Through to the lower frame edges (widest point) : 295mm

If using the Pragmasis Anti Pinch Pin, you would need the 390mm pin if used with their approved 16mm chain and padlock. They advise 90mm over the length of the widest point.

I have not yet spoken to them about the length of chain needed if a ground anchor was just below the bike.

Thanks! The swingarm tube now has its own section:
