Harley Davidson still sells their Bar & Shield Padlock, which is actually a Masterlock #220. See photo #1.

However, Harley Davidson has discontinued their high security padlock, part #45721-96A, which was actually a Masterlock 6127. See photo #2

Harley Davidson replaced their high security padlock with the Shackle Lock Kit, part #94868-10. See photo #3

The Shackle Lock Kit is actually a Kryptonite Evolution Series 4 Disc Lock Premium Pack. I believe the reason Harley Davidson replaced their high security padlock with the new shackle lock kit is because its size is better suited for securing a disc brake or sprocket, and I don't believe the high security padlock was selling well, unlike the Bar & Shield Padlock. The lock has a very wide shackle width giving the user more places or options for using the lock. This is a descent lock and comes with a disc detainer cylinder, which in my opinion is extremely difficult, if not impossible, to pick. Kryptonite is know for selling high end locks for motorcycle and bicycle security, and in my opinion was a smart choice by Harley Davidson.
You can actually buy this lock with the Kryptonite label for about $15 less than the Harley Davidson price. Use this link:
