In my opinion the headstock connection with double downtubes and headstock bearing is no added value. The engine, drivetrain of the K-series is solid and stable, it is bearing all the forces. That is the reason i refrained from the complex, heavy forward downtubes. I'm running my second K75 sidecar now and there is no lack of stability.AL-58 wrote:That subframe is a good starting point. Can be improved by taking the front upper mount up to the steering head instead of stopping at the upper engine mount. Makes a huge difference in handling and removes the risk of front downtubes breaking.

would you have a few measurements to go with the pics to speed things up a little, the length of the sub frame tubes and the dimenssions of the rear plate would be great if you have them thankshalflive wrote:I presume you have found my subframe?

In the meantime i've made a new subframe for another sidecar on (almost) the same K75. I will see if i have made enough pictures to add another chapter.
You are completely welcome to your opinion. I've actually had both types of subframe and know from experience that it does make a world of difference to the overall handling when the top front mount goes closer to the steering head.halflive wrote:In my opinion the headstock connection with double downtubes and headstock bearing is no added value.

The stability comes from the rugged suspension, low car tires and the stable Earles fork.
