Stoplock heavy-duty motorcycle lock SS5275 – robust anti-theft chain
If you want to leave your bike with a bit more peace of mind, the Stoplock SS5275 is a proper no-nonsense option. It’s a straightforward, heavy-duty chain made from hardened steel — chunky by design so it won’t be the quick snip a thief is hoping for. That weight and build are deliberate: if your bike’s worth protecting, this gives you something that actively discourages an attempt rather than inviting one.
Key features
- 10 mm hardened steel shackle and a hardened steel lock casing — built to stand up to bolt croppers and common hand tools.
- 1.2 m chain with high-visibility yellow powder coating for added corrosion resistance and to make it obvious the bike’s secured.
- Supplied with keys and a dependable key lock mechanism — straightforward to use and reliable in day-to-day use.
- Perfect for locking the bike to fixed points like lamp posts, ground anchors or sturdy railings.
- Weighs around 2.52 kg — heavier than lightweight convenience locks, but that’s the trade-off for proper security.
How this helps
Whether you’re nipping into the station, popping into the pub or leaving the bike overnight, this chain provides a solid physical barrier that makes theft much harder. Most thieves go for easy wins; a chunky, visible chain usually puts them off. It’s the sort of lock that lets you get on with your day without faffing about with flimsy cables and wondering if the bike will still be there in the morning.

Practical tips and common questions
- Thread the chain through the frame and a wheel where possible — that makes it far harder to ride or wheel the bike away.
- Use a solid anchor point and try to keep the lock off the ground to slow down any attack and reduce water getting into the mechanism.
- Carry a spare key separately and check the lock periodically for grit or corrosion; a quick wipe and a dab of dry lubricant keeps it turning smoothly.
- Be realistic — this is heavy-duty and resists bolt croppers and hand tools, but no lock is utterly invincible against power tools or a determined thief. Combining locks or using a ground anchor will improve security further.
All told, the Stoplock SS5275 is a straightforward, visible deterrent that’s ideal for daily commuting, overnight parking or any time you’ll be leaving your bike unattended for a while. It’s not the lightest thing to carry, but if security matters more than a few extra grams, it’s a solid bit of kit.
