SS105 vs SS101: Why Your Ground Anchor's Certification Actually Matters

Not all Sold Secure Diamond ratings are created equal. Here's what the certification codes actually mean — and why it matters for your bike's security.

When you see "Sold Secure Diamond" on a motorcycle security product, you probably assume you're getting maximum protection. But there's a critical distinction most buyers miss: Diamond ratings from different Sold Secure specifications test against completely different tool lists and attack durations.

If you're serious about protecting a high-value motorcycle, understanding the difference between SS105 (Ground Anchors and Security Posts) and SS101 (Powered Cycles) could be the difference between your bike staying put or disappearing overnight.

What Do SS105 and SS101 Actually Mean?

Sold Secure is an independent security product certification agency that works with companies and police forces worldwide to test and assess the performance of security products against rigorous attacks. Sold Secure's 'attack test' measures how long a product can withstand attempted removal, within a specific time frame and against a comprehensive list of tools.

Sold Secure operates multiple certification schemes, each designed for specific product categories. The two most relevant for motorcycle security are:

The Critical Difference: Tool Power and Attack Duration

Here's where SS105 pulls ahead.

SS101 Powered Cycle Diamond

SS101 tests portable locks with:

• 5-minute attack cycles using Tools Lists A, B, C, and D
• 90-second 36V angle grinder test (shorter duration)
• 100kN bolt crop test

The 90-second grinder test is a key distinction — it's a shorter, dedicated test specifically for angle grinder attacks on portable locks.

SS105 Ground Anchor and Posts Diamond

SS105 tests fixed structures with:

• 5-minute attack cycles — full duration on every attack, including angle grinder
• Tools Lists A, B, C, D, and S — specialist tools permitted
• Higher powered tools allowed compared to SS101
• Heat attack (gas torch) — tested under Section 5.14

No shortened tests. No reduced attack times. Every attack method gets the full 5 minutes, with more powerful tools than SS101 permits.

Why This Matters for Ground Anchors

Ground anchors are fixed in place. A thief can't simply cut a chain and run — they have to defeat the anchor itself, bolted to concrete.

This is why SS105 exists as a separate standard. Thieves attacking fixed structures use:

1. Higher powered angle grinders (more than 36V)
2. Sustained cutting attacks (full 5 minutes, not 90 seconds)
3. Thermal attacks (heating metal until it loses temper)
4. Specialist tools from List S

SS105 tests against the full toolkit. SS101 doesn't — it has reduced attack times and lower power limits appropriate for portable locks.

What This Means for Your Motorcycle Security

Chain + Ground Anchor Combinations

Most "ground anchors" on the market are SS101-certified because they're tested as part of a chain/lock system. The anchor itself might only hold a Gold rating — or the Diamond rating applies to the chain, not the anchor.

The weak point: Even a Diamond-rated chain is only as strong as what it's locked to. If the anchor fails under sustained attack with higher powered tools, the chain becomes irrelevant.

SS105-Certified Ground Anchors

Products with SS105 Ground Anchor and Posts Diamond certification have survived:

• Full 5-minute angle grinder attacks (not 90 seconds)
• Higher powered cutting tools than SS101 permits
• Specialist tools from List S
• Gas torch heating + leverage attacks
• Multiple 5-minute attack cycles simulating determined theft attempts

This is why insurers and security professionals specify SS105 for high-value motorcycles. It's not snobbery — it's the only certification that tests against the full toolkit thieves actually use on fixed structures.

The TufLuck Example

The TufLuck ground anchor system achieved SS105 Ground Anchor and Posts Diamond certification by surviving 12 separate 5-minute attack cycles, each using different tools and methods.

Total attack time: 60 minutes of sustained assault.

Tools used across the 12 tests included:

• Sledgehammers
• Angle grinders (higher powered than SS101 allows)
• Heat torches (gas attack)
• Drills
• Chisels
• Specialist cutting equipment (List S tools)

The system remained locked.

This isn't about passing a test once. It's about systematic resistance to every attack method in the thief's playbook — including the higher powered tools and extended attack durations that SS101 doesn't test against.

How to Check Your Product's Certification

Don't trust marketing claims. Verify the certification yourself:

1. Visit soldsecure.com and search the approved products database
2. Check the specification code — look for "SS105" not just "SS101"
3. Verify the category — "Ground Anchor and Posts Diamond" is different from "Powered Cycle Diamond"
4. Check the tool list — SS105 Diamond includes List S tools; SS101 does not

Bottom Line

If you're locking a £10,000+ motorcycle to a ground anchor, SS105 Ground Anchor and Posts Diamond is the certification that matters. SS101 Diamond is excellent for portable locks and chains, but it tests with lower powered tools and shortened attack durations.

The certification codes aren't marketing fluff. They represent fundamentally different test protocols — SS105 with higher powered tools and full 5-minute attacks, SS101 with reduced power limits and shortened grinder tests. When your bike's security is on the line, that distinction is everything.
