Hi all, i'm in the middle of a cafe/custom build and as I am beginning to put everything back together i became interested in lowering the front end. In other forums and pictures iv'e seen the forks moved up in the triple tree, but without clip-on bars this method does not work as the bars are in the way (clubman bars).
My question is if there is another method to lower the front end.
I've thought of cutting down the plastic preloaders inside the fork tubes but didn't know if that would cause too much bottoming out.

Thanks!

I used some 20mm risers so the bars were 20mm higher and then the forks went through 20mm futher.

Thanks for the advice! That would definitely be another possibility.
What would your opinion be on downsizing the preloaders?

I would not do it as it will leave slack and will rattle and bang over the bumps

Be careful. With the stock geometry these bikes have precious little trail. This is why they develop a scary weave when you try to corner them fast fully loaded. The fork is compressed by cornering loads, and you quickly enough run out of trail, making the bike unstable. Stiffer springs only masks the underlying problem. Lowering the front end, or fitting a smaller diameter front wheel makes the problem worse.

The cure is to fit different triple clamps with less offset. This adds trail. Then you can lower the nose to speed up the steering without making the bike unsafe at speed. Another way to do this is to fit a complete front end from a mid 1980's Suzuki GSX/R 1000, which had right side up forks like the K. The GSX/R uses the same head bearings as BMWs do. Other than stem length and fettling brake hoses it is a nice bolt on that does wonders for the steering. It is a fully adjustable cartridge fork too. The Suzuki front wheel matches the BMW three spoke wheels close enough that no one but the most anally retentive K bike nut would notice.

Just saying ...........
