This lock can also be used as a motorcycle disc lock if there is an opening of at least 21mm but not larger than 40mm (1-9/16"). 
Next to being impervious to physical attacks, the high security floating disc key-way makes this lock extremely difficult to pick.>

  • 21mm - 0.82" heavy steel shaft.
  • Rotating parts provide no leverage.
  • Anti-grip slanted and rounded sides.
  • Chrome finish
  • 3 high security keys.
  • Dust and water cover.

I bought a Pragmasis RL21 SFB RoundLock Padlock - Disc lock from Lockitt and nothing was a problem. We usually have a bit of a struggle getting parts/items here in the middle of the Pacific but Lockitt was fantastic. The shipping was fast and communication was great. The lock is just what I needed. The size makes it perfect for touring without hauling around too much weight. And the security rating from European websites gives me plenty of confidence. Happy, happy, happy!!!

i really like the way this lock makes access difficult for thieves. it is heavy and doesnt leave much room to grind it easily. it got a great review on bennit (think its called,) and that site is very reputable and gives non biased reviews. don't buy a cheap amazon disc lock thieves got through two different ones had in less that 30 seconds if that. if this lock had an alarm it would be even more perfect but most disc alrams are so damn sensitive

A beast of a lock - use with or without chain. Nobody cutting through this guy - will have to carry your bike away (good luck)
Exceptional Chain Lock

There is an excellent 4 minute video on YouTube about this lock and another 4 minute video about the Pragmasis Protector Chains it fits perfectly. I am extremely happy with the two RL21 RoundLocks I have! This lock has achieved "SOLD SECURE MOTORCYCLE GOLD" accreditation in Europe and is ideally suited to use with the serious security Pragmasis Protector Chains (13mm, 16mm). The RoundLock fits snugly against the edges of the chain`s links, protecting it, making it very difficult to attack. When attacked (in a YouTube video) with a sledgehammer, the lock merely deformed (the shape of the lock itself makes it very difficult to hit squarely). It`s inaccessible with bolt croppers, and is so thick that an angle grinder attack causes little damage – in fact the chain is the easier option for a crook to attack. I think it’s an incredible chain lock! Check out the YouTube videos.
