Principles of operation
The ABUS 80TI/50 padlock is a standard pin-tumbler lock with a paracentric keyway, and six pin pairs. While the key pins are the traditional design, the driver pins are various security pin shapes: spooled, serrated, and special T-pin shape that suggests it is intended to provide protection from bumping attacks.
When all the pins are lifted to the shear line, the plug can rotate clockwise.
The ABUS 80TI/50 can only be opened by rotating the plug clockwise.

The ABUS 80TI-50 cannot be disassembled non-destructively; to disassemble, you have to drill open the seventh pin chamber and remove the retaining pin and spring. Be warned, you can't use a follower or a shim, maybe a modified pinning shoe will work. If not, the driver pins will shoot in the empty chamber when you pull the plug out.
The ABUS 80TI/50 is vulnerable to "over lift" attacks, where the entire pin stack can be lifted, using a comb pick, into the driver's pin chamber, allowing plug rotation.
The ABUS 80TI/50 may be vulnerable to one or more of the following:
