In response to my own question and to send this post to the round file……….. Having taken a closer look at the Sachs reversal possibility, whereas the shock would probably be mechanically functional flipped around, – it is almost horizontal in it’s present mounting configuration anyway, the reservoir would also have to be mounted on the swing arm in static proximity to the shock head reservoir hose banjo fitting, - not impossible. Although access to the threaded ring adjustors would then probably allow for use of a shock spanner to turn the adjustors there would still be marginal structural interference by the passenger foot rest support tube, - but at minimum, at least better access than present configuration. It was a thought. Maybe in a future rendition of the Empulse R ?
