Does anyone out there know if a k100 lt top box will fit on a k75? 

Thanks, hive mind..

Short answer yes but your Brick must have the OEM tail rack. And it is important that you get all the parts with the top box the mounting plate and the locking pin. The 22lt OEM top box requires the fitting of a plate between the OEM rear rack and the tail. The top box is then placed in position and a internal pin fitted with a cross pin is located into the slot in the plate and rotated until it locks in. When bought new the top box kit also included a piece of clear contact to cover the tail preventing scratches. I've just managed to pick up two for my K75s.

Thank you very much! 

Just spotted one on ebay!

I've seen the mounting plates and pins selling for $50.00 Au each. They often seemed to get separated from the top boxes. Since swapping over from the 33 Lt Shad top box the handling in windy conditions has vastly improved. If it doesn't come with a key they can be re-cut. Due to the way the lid is mounted ( hinged at the rear) some Bricksters have experienced the lid flying up while  riding. There are two solutions keep it locked and make sure the catch has engaged. the second method involves fitting a strap around or on the lid. A less often reported problem is that the "T" pin rattles and the top box is slightly loose. Both mine are tight however if yours is loose a washer under the pin should tighten it up. When I got both of mine the foam rubber strips on the lower surface of the mounting plates were rotted out. These are easy to replace with 1/4" thick foam, and I think this only comes into play if you are going to run without the top box it stops the plate from moving around. As an aside there was a optional top rack available but it very rarely comes up for sale.

Which top case? The 22L or the bigger one that came on the K100LTs?

This one.  It comes with the bracket.  I have side paniers but I have to get through a narrow gate sonhave to take them off every time.. also wouldn’t mind a top box too!

Seems like a good deal. As mentioned, all you need is the BMW tail rack to mount the 22L top case.

Here's how to mount the rack:

Cool. I take it that it is the one fitted as standard to the bike? If so then that’s he one I have.

Looks like this:

Locking it doesn't necessarily keep it secure. It's a flimsy latch system vulnerable to being affected by vibration and shock. Strapping it closed or attaching a hasp and staple make the lid secure.

One of the top boxes I purchased didn't come with a key, I tried the two keys that I had and they didn't do it. However on the way to the locksmiths to get the key cut I dropped into a mates place. He's got Four bricks so I asked to try all his keys, as luck would have it the first key I tried worked. With the correct key you can remove the cylinder. With it removed I inserted my key and filed down the protruding wafers, so now I one key that fits all the locks on my Brick. I can also open the panniers on two of my mates bricks and when I ordered a complete new set of pannier locks from the UK my key fitted. So before you take it to a locksmith it will pay to try as many Brick keys as you can lay your hands on. On the first top box I bought I've also added extra lid restraining straps.
