Security
The grade your insurer asks for is published. Read it before buying, not after a claim.
An independent certification. Sold Secure, ART — outside bodies, graded, recognised by insurers. Sold Secure grades run up through Gold to Diamond; ART publishes numbered levels.
A house scale. “Security level 4”, “8/10”. A maker’s own ranking, consistent across its own range, and not an outside assessment.
Both appear in product titles on this shelf and they read identically to someone who does not know the difference.
Insurers publish the grade they require, and it usually depends on the value of the machine. Buying a Gold lock where Diamond is required is buying a lock and not a claim.
That is a two-minute check and it is the only one that decides which lock you need.
Whether you will use it.
A two-metre chain at the weight two metres of hardened steel actually is, carried on the machine, is a chain that gets left at home by March. One maker in this catalogue publishes its whole range as lengths paired with weights, which is the only way to make that trade before buying rather than after.
A chain in this catalogue is titled by its own maker as a bicycle lock, with motorcycle use appearing in the bullets. It is well made and its hexagonal link section is a genuine construction advantage. What it is sold as is still worth knowing.

In this catalogue, Sold Secure and ART. Both are assessments by outside bodies, published as grades, and both appear in product titles where a maker has earned them.
A maker’s own scale applied across its own range, so its products can be ranked against each other. It is consistent and it is not an outside assessment — two brands here publish one.
Certifications are marked on the product. As with armour and helmets, the marking on the item is the document, and the listing is a description of it.
For : Parking against a fixed object, with an insurer that asks for a Gold-grade lock.
Main strength : Sold Secure Gold is an independent insurer certification and it is published as such
Main limitation : No weight published for this length
For : The middle of the reach-against-weight trade, on a machine parked at the same place most nights.
Main strength : 30 cm more reach than the 120 cm version for 700 g
Main limitation : 4.5 kg carried, or left where the machine is parked
For : A machine worth more than the lock, parked where it is left unattended and insured.
Main strength : Sold Secure Diamond is an independent certification at its highest grade, and it is in the title
Main limitation : No alarm — the deterrence is entirely mechanical
For : A scooter or a light machine, where 2.95 kg of chain is a weight worth carrying.
Main strength : Hexagonal links resist a bolt cutter’s jaws better than round ones, and the shape is published
Main limitation : It is published as a bicycle lock — the motorcycle use is in the bullets, not the title
For : A scooter parked where the maker says this lock belongs: somewhere theft risk is low.
Main strength : The maker publishes the risk level its own product is for, which is an unusual piece of honesty
Main limitation : A 5 mm pin is the thinnest in this family — the neighbours publish 7 mm and 16 mm

Head-to-heads already published between two models from this guide or this aisle.
The models here come from the catalogue of this site. Specifications are those published by the manufacturer and on the Amazon product page; prices are what Keepa reported on the date below, and both move. The ranking uses declared specifications, the balance of stated strengths and limitations, and price. No product on this site has been physically tested, and nothing here claims otherwise.

Nothing written into the text below is a current price. Where an amount appears in a sentence, it is the reading taken on the day that sentence was written; what a shop is asking at this moment loads beside the product itself, and that is the figure to go by.
Helmets and riding gear are discounted over and over through the year — hardest of all in the weeks when nobody is riding, which is months away from when most of it is bought — and a struck-through figure on its own says nothing whatever about what the same model was charged at four weeks ago. UniverTrack holds a week-by-week history for every retailer, which means a reduction is judged against a price somebody actually paid rather than one dreamed up for the sale — and it tells you when the moment to buy has genuinely come.
