When you absolutely want to keep your motorcycle out of the hands of thieves, all you can do is make it as inconvenient for a thief as you can. Battery-powered angle grinders exploded in popularity as a tool for theft about a decade ago, waging war on locks and chains. A UK-based security company was founded to combat this threat, and the Hiplok DX1000 lock ($380) and Mega chain ($230) we tested left us convinced of the success of its anti-angle-grinder lock efforts.

One thing we didn’t do was try to destroy the lock and chain ourselves. There are enough YouTube videos of vain attempts that we were convinced of the near-impermeability of the Hiplok DX1000’s ceramic-composite-reinforced shackle, as it ate grinding discs for lunch. Also, French lock-picking champion Nicolas Florent was unable to pick the lock, so that’s reassuring. You get three keys with the lock, and they’re coded in case you lose them or need spares.

The Hiplok Mega chain is not quite as formidable as the lock, though the 22mm hardened-steel links will deter any reasonable attempts at theft. Like the DX1000 D-lock, the chain is Diamond-rated for motorcycles by Sold Secure, an independent testing company, and that’s good enough for us. So, instead of going on a destructive rampage, we spent our time using the DX1000 lock and the Mega chain.

The first thing to know is that the Mega chain is not something you bring with you on a ride. The 4.25-foot beast weighs over 27 pounds. We use it in the garage, or when transporting a bike in a truck or van.

The Hiplok DX1000 lock weighs 6 pounds even, so it’s reasonably portable. The main opening is 4-by-7 inches, roughly, plus the tapered portion at the top. You can use it in conjunction with Hiplok’s MD1000 disc lock ($200), which we haven’t tested, to prevent either wheel from rolling. Again, anything can be stolen, so it’s all about preparing a deterrent that sends the thief elsewhere.

The small end of the substantial Mega chain fits between the wire spokes of the wheels we tested, ranging from 18 to 21 inches, as well as pretty much any mag-style wheel. The chain’s sheath does a fine job of protecting the wheel from damage. The coating on the DX1000 lock also protects the motorcycle’s finish.

The DX1000’s keyhole is protected by a rubbery tab with a waterproof plug. The lock cylinder is recessed, further protecting it from tampering. The key’s action in the cylinder is reassuring, and you can feel the double locking-dogs securing the shackle. Once engaged, you realize you never want to lose the key when you’re away from home.

If you’re looking for additional home security, Hiplok offers the adjustable AX1000 anchor ($500) and compact A1000 anchor ($250), though you’ll have to spend some time or money installing them. We tested neither, because once embedded in concrete or brick, it is considered immovable. Again, these anchors get the highest rating from Sold Secure.

At $610 and 33+ pounds, the Hiplok DX1000 lock and Mega chain are serious security devices. You’re in for over $1100 if you add in the high-end AX1000 anchor. However, if you have a motorcycle you don’t want stolen, this is a way to show thieves you aren’t playing. The Hiplok DX1000 lock and Mega chain are the next best thing to sleeping next to your bike with a Kel-Tec KSG at the ready.
