>kryptonite d locks

I have a couple of Kryptonite mini-D's, they're handy for portable/improvised security. Will lock a chain, go through a disk or the rear sprocket etc.

I use a Kryptonite mini D lock - www.amazon.co.uk/Kryptonite-York-Liberty-Disc-Lock/dp/B000GVFLIO Very solid and heavy little fellow with good security ratings. I have a high-end chain, but don't use it unless in risky situations. Just whack the d lock through the disk - both legs passing through the disk. If I need to replace it, I'll probably get the Pramasis DIB lock - seems equal or better and same price roughly, and Pragmasis is the top name nowadays.

Main thing is, get a proper quality lock. Thieves recognise cheap crap, and they recognise proper kit that's going to cause them exposure and delay. If money's tight, better to put a high quality padlock through the rear sprocket (eg https://www.amazon.co.uk/ABUS-24673-Titalium-Monobloc-Padlock/dp/B00NGOQEY8/) than rely on Chinese pot-metal rubbish.

This is more of a home lock than a travel lock, that being said when I've travelled with it I wrapped it with an old tee shirt and put it in a sissy bar bag. The weight shift was interesting on the first turn. :)

ed: I also have a Kryptonite New York Bicycle Disc Lock which I mentioned earlier but didn't link to. This is what I use for travel around, it has a bright yellow disc lock reminder cord that is visible to you so you don't drive with it on and visible for passers-by so they hopefully passby.

>Does anyone know if a pragmasis 19mm chain (or maybe even the 22mm version) and the Pragmiasis roundlock combo will fit on a ninja 300 (non abs)? > >The roundlock works as a disc lock. Can it fit on the ninja 300 rear disc? Is there a way for me to check? >

Excellent choice. A chain is pretty generic, should 'fit' any bike. Through the back wheel is standard option, but for extra security you might want to try and loop the frame or swing arm too. Have a look at Pragmasis pinch-pins, really clever way to easily lock through the core frame.

The roundlock is brilliant and definitely locks 19mm chain, but whether it fits a particular brake disc varies. You can't lock the disc and the chain at the same time anyway. To do that you would need a D lock (Pragmasis Dib is excellent but a little bulky, I personally prefer the Kryptonite 18mm mini D) which doubles as a carry lock. If a lock doesn't fit front disk, there are still rear disc and chain sprocket options.

Remember you must lock the bike to a solid anchor, so think about what's available and where you can conveniently park the bike. If there isn't a strongpoint within a few feet, you'll need a ground anchor. If you have strong concrete available there are many excellent drill & fix anchors available. For a weaker "garden path" slab, use injected resin rather than expansion bolts.

Sometimes it's easier to create the anchor exactly where needed - dig a hole you could drop a microwave into, fill with two bags of concrete (£10 from B&Q), and embed a "concrete-in anchor". Rig some sticks to hold it in place for 24hrs until the concrete stiffens up. If you don't want to dig, the same effect can be achieved by filling a large container. DIY concrete weighs around 2kg per litre, so for a surface anchor you need 30-40L. If you're cheap & practical, any discarded plastic container is fine for this. If you want aesthetics, use a nice ceramic plant pot and surround the anchor loop with a surface layer of gravel or plants.

Finally, for pity's sake fit a GPS tracker. Nothing will stop a determined thief, but they generally don't take stolen bikes directly to their base because of trackers. They often park a hot bike somewhere anonymous and out of sight, and wait a day or two to see if the cops arrive. If you have a GPS tracker, you can just go and get it. Search the sub for many previous discussions.

Like other have already stated you need multiple good quality locks. Star by purchasing 2 and move up to 3 or even 4.
