Morning all.

does anyone happen to know the vital statistics of the K100 top yoke?

Stanchion diameter is 41.3mm. That's common knowledge. I've managed to find one reference online to the fork centres being 190mm apart but nothing to confirm that. And I've not found anything at all for the offset.

Cheers in advance.

Rich.

56 mm.

Crackin', many thanks.

Are you able to confirm the fork spacing of 190mm as well?

190 mm is correct.

I'm assuming we're speaking about the Fichtel & Sachs fork as you did mention 41,3 mm as dia.

I didn't even have to duck as that went over my head.

I've no idea even what a Fichtel and Sachs fork is. The bike is a 1984 K100 RS and I have no reason to suspect it doesn't have standard forks fitted. It definitely has 41.3mm stanchions though as my 41mm clip ons were a "snug" fit. 

you are a man with much knowledge Mr Inge. Thanks.
