Best Idea For Disc Lock I Seen So Far.

Or any radial calliper too?

 

But how thief-proof is it?
Anyone done any tests?

I think one of the worst things about disk locks is that people think they provide protection when in reality most of them provide none at all. Maybe this one does. My Abus one is about as good as it gets (or got 10 years ago), but even that is only good for a few minutes with a determined thief who knows what he's doing (assuming the bike isn't just rolled into a van).

 

No one wants to steal your wreck Lucas, I mean there is not even scrap value steel in yours given the rust!!!

 

It was branded by KTM as you said Lucaz, I was going to put one on my RC8R until I saw the price.

 

If you think your lock is any good, watch some of these...

I use a tiny, cheap, brass padlock.
The crucial thing about this is that its small enough to fit on the disc in the gap between the (non radial) caliper and the fork stanchion.
Once in position its almost impossible to get at in order to pick the lock or grind it off, so it doesn't matter that its not all that strong.
Its also small enough to carry around quite easily in your pocket.
I couple it with a reminder cord, but not the usual type which is too bulky to carry around. Mine came on a cheap, plastic keyring thingy from the local pound shop and is just as long as the normal ones but smaller diameter, softer and more flexible, so again its no prob to stick it in your pocket.
I use this all the time when I'm stopping for just a short while or in a safer parking area, but obviously a disc lock is no protection against anything other than the casual thief.

Next to that, I rather like Xena alarmed disclocks, but my older model is a bit bulky and is sometimes erratic.
The newer ones are better I believe, and even the smaller ones intended for scooters are probably adequate if they'll fit your discs, as its more about the alarm than the strength of the lock really.....and again small means easy to carry around.
I tend to add that on the back wheel with the little padlock on the front, thus the whole bike has to be lifted and carried away (unless the locks are removed of course).

Not sure that I'd really want the extra unsprung weight and general untidiness of the one you list Lukasz, but it is an interesting design which has some advantages over the conventional type.

 

If buying one for insurance purposes or to declare as a mechanical device check with Thatcham. The device itself isn't (or at least until March of this year) wasn't thatcham approved. Essentially the fee for the accreditation had run out last year yet roadlok and the uk distributors continued to refer to the accreditation even up to the early part of this year.

The KTM POWERPARTS item certainly isn't thatcham approved. According to Thatcham, the device, if touted as a separate manufacturer's product has to individually tested.

Also, from memory, the US version is different to the UK version. It is the UK version that carried the Thatcham accreditation, not the US one.

Take away the thatcham issue (perhaps the issue is resolved now) and it's a cracking device and extremely light.

I looked at purchasing one last year and the early part of this year. Ultimately neither the UK distributor nor KTM could tell me that the device met with thatcham approval whether or not it was the KTM POWERPARTS or merely the one marketed and sold by roadblock themselves to fit the KTM and so for the that reason I left it.

 

This is a brilliant link. Thanks!
I've now spent hours watching this guy pick and explain locks. Fascinating. It has also convinced me that I am right to put my faith in Abus. They do seem to be top quality locks.
