Just thought I would share my experience with cb500f 2019. Seat firm but not bad, but pain after about 75miles, also have a bad back and any small pot hole would shock my back. Fit Air Hawk seat it wasn't for me, so remove airbag and replace with medical memory foam, slightly better but still not happy. Send seat off for memory foam mod to specialist. 75% better. Slack off rear shock to softest setting, adjust front to match, try again better but still not happy. Take bike to London to Hagon Shocks left it with them for two weeks and they made a shock to suit me, fully adjustable for spring bump and rebound. Brought it home in the van so haven't ridden it yet, but what a difference, the adjustment on damping even on 1/4 turn makes a difference to the feeling. It's like bouncing on a majic carpet I just cannot wait to ride it. I will update after road test.
