K75S Comfort Improvements - Handlebars and leg heat

[grosbeak]

Hi folks,

Two issues have made my 1992 K75S less comfortable for me than it might be - the position of the handlebars were too low and far forward and there was too much heat coming from the sides of the tank. I have made modifications to address these problems.









I got the bar risers from Voigt Moto Technik in Germany. A test fit proved that there were no issues with wiring, cable or hose length. I fabricated some brackets out of 1/8" aluminum to relocate the dash pad and rear cover to their new locations.














And I got the tank insulation material from Amazon - Thermo-Tec 12" x 24", qty 2








The work included removing the fairings and the tank, neither of which I had done before. Details to follow.

I'll be working on a video soon.

Be aware that when putting bar backs on early K75Ss, that due to the shorter throttle cable on the early bikes, you may have unintended rpm increase when the bars are turned all the way to the left. Removing any wire ties that hold the throttle cable to the frame will help.

Very nice! Please show in the video or explain here how you fabricated the brackets.

It will be in the video for sure but here are the highlights.

I needed 3/4" wide x 1/8" thick aluminum flat bar. The stuff I found online was 1" thick and I found that I could cut it to width on my table saw, which made a lot of noise and mess. The aluminum was soft enough not to damage the saw blade's carbide teeth.

After a fair bit of trial and error I arrived at these measurements:



It's not shown here, but the top hole is drilled to 13/64" and tapped to M6. The bottom hole is drilled to 1/4". Also, I got to buy a new tool - always a bonus. Here it is... a vice mounted metal brake:



Bending the brackets was easy with the new tool but I reckon you could do it with the vise and a hammer.



The bends for the dash pad brackets turned out to be 90 degrees...



The ones for the back cover were milder. They also got some heat shrink to protect the wires that pass near them.





It was a job of work but I am really pleased with the results. The changes are not drastic - 30mm up and 21mm back - but a 90km test ride afterwards and the riding position was definitely more comfortable.

Thanks! I figured it out eventually!
