There are many different Motorcycle security that can be purchased to keep your bike safe.
But which is best?
Surveys have shown that to have no security greatly increases the theft of your beloved motorbike. Something is better then nothing!

Some use a simple
Disc Lock Once you have parked your motorcycle up, attach the disc lock to prevent theft. Some Disc locks have reminder cables, the worst thing you can do is forget that you have put a disc lock on your bike and ride away, or try to ride away. So if you are using or thinking of using a disc lock always put a reminder cable on as well. The
Disc Locks are light and easy to carry
There are also
Security Chains and Locks. This are good if you have a suitable place to park and can put the chain around something that is secured to the floor. Some use
Ground Anchors wrap the chain around and secure it to the motorcycle.
Which is best?
Well the Chain and lock are more substantial then a disc lock, but it depends on where is motorbike is located during a period of time. If you commute to work on your bike, the chain and lock would be a great idea, if however there is nowhere to anchor the chain, then the disc lock would be equally as good.
Some Disc locks can also act as an alarm and if the motorbike is moved at all then the alarm will ring out notifying you that the motorbike is being moved.

So I would say that while at home whether in a garage or not, you use a chain and lock with a ground anchor. Then while at work a Disc Lock would put the criminals off from taking your bike.
There are different types of locks, but always look for a "sold secure" or Thatcham Approved as this wil also reduce your insurance premiums.
Hope this helps you decide which way to go on security for your motorcycle and don't leave it too late...
