fog rain wind snow heat resistant lock.. On my bike I have another lock that I use and three other locks. By far the best I have.

I have had the product for many years. I lock a Yamaha FJR 1300 with it. It has been exposed to rain all these years and the lock has never had any issues. It still opens and closes with the same ease as the first time. It has a cover where the key goes. The only negative is its large weight. You can't take it with you. It is meant for a fixed location. The key is about 5 cm long. I have the impression that it comes in two sizes, I have the large one, which is over 1m, and I think the small one is around 60cm.
