on my Ktm ive got a pragmasis chain and pragmasis round lock (or use as a disc lock see comment about round lock not compatible with some bmw discs on link below but might work on a rear disc??)....ive seen videos of bikes stolen by thieves breaking a disk lock by repeatedly hitting with a brick and the metal breaks- I don't think they would have any joy with the round lock
The round lock is tested by Bennetts and they couldn't beat it. It's a weighty thing for something so small and being small/round it could prove tricky to grip without losing a few digits to the angle grinder!
At just £39.99, the Pragmasis RoundLock is one of the toughest disc locks we’ve tested. Could this bargain budget lock be the best option? Full review…

While parked at home (alarmed garage) Ive also got an Oxford boss alarmed disc lock on the back wheel, Oxford ground anchor (with above chain) , and a MoniMoto tracker but reception seems a bit iffy on it so might need to check where ive hidden it is ok.
