Decided to give up on the project due to lack of time. All the parts are 1991 K100RS 16 valve parts and anything that I sell is in good condition. The Corbin seat has gone, but I still have:
Pair of floating front discs, as new only covered around 5000 kms, These are around £135 each, so I am asking £120 the pair.
Rear Ram shock, covered less than 5000 kms. Check length as I believer that 8V, 16V and K1100 have different lengths. Cost around £330 new, looking for £200. This makes a huge difference to the bike and the adjustment is great.
Two sets of 3 spoke wheels, no dents all in gold. Looking for £100 a set.
Set of early panniers with mounting Z bars, bit tatty but new hinges, £80..
Various fairing parts including black screen with small spoiler. Engine is a smooth as they come with no leaks and new rubbers all round. 7 inch round headlight with brackets to fit the forks (not a BMW item).
Everything is here in France and postage will be on top if the prices. Larger items would need collecting.
Payment by paypal only please.
Let me know if you want pictures of anything.

Nope, they don't fit....

All K75 have 285mm solid discs while 16V models have 305mm. Unfortunately, the only way to make them compatible is an entire front end swap, plus many important ancillaries.

Crap, I was going off this https://www.motorworks.co.uk/vlive/Shop/Parts.php?T=5&NU=15&M=40&Ct=IA&SbCt=BA_15_40_IA_50 which makes it look like the K75 and k100 discs are interchangeable.

K100 2v discs and K75 are interchangeable.

K100 4v engines have different front ends and different discs, not interchangeable with K75.

Just to be nitpicky, replacing the entire front end is not the ONLY way.  For example, Special K Larry built some custom caliper brackets on one of his K75s and used a 20mm 2V master:



(And then he put the rotors on backwards.  )


I know of somebody else who did something similar to make the 4 pot brakes work with K75 forks.

without hijacking this threat too much - i will probably have to replace - renew the forks anyway so all information here is great

I do have the whole front end including the forks, but beside having fully floating discs I think that fork tube diameter may also be different.
The 16v was the fist attempt to bring the K100 up to modern standards, in its day, and had better brakes with ABS as standard, wider wheels for radial tyres, and 10 bhp more than the 8v. It also had the newer paralever rear.

Having done three of these front end conversions to K75s, there's other issues you run into:

1 - Yes, you need to swap fork trees due to different fork tube diameters.

2 - On the 4v bikes, the ignition is built into the upper fork tree whereas on the 2V bikes the ignition switch is mounted in the dash pad.

3 - The dash pads for the 4V bikes mount farther back on the upper fork tree. There's a couple of ways to deal with that issue.

My OZ-based K100RS-8V has four pot Brembos from an R1100GS on a K75S three spoke 18" wheel and radials with 292mm Suzuki discs and aluminium spacers on an 'S' fork with a 20mm master cylinder from a K1100RS. 

There are ways, but if someone's enquiring about one for one I wasn't going to give them the thumbs up, she'll be right, mate.


There is work needs doing.

This is will be down at BobT's in June as I must deliver Christmas pudding to Mrs BobT and do my annual confit restocking.....may be able to bring back a few K bits to Ireland.
