One aspect of many aftermarket seats we’ve tried in the past is that their vinyl and seat foam are much firmer than stock. We’ve found many of them to actually be less comfortable than the stock saddle in longer stints, with the added disadvantage (in our opinion) of being more slippery than the stocker. The Zero Gravity seat, on the other hand, is much more comfortable than the stock unit, with more “give” in the foam without losing the road feel that is crucial in sport riding. After several longer rides, we noticed much less discomfort than would usually occur. The vinyl is also grippier than the stock seat, meaning you can keep your lower body position in place a lot easier during hard acceleration (relying too much on your arms/hands to hold yourself into place under acceleration can add unwanted input into the steering, possibly contributing to a tankslapper).
