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.

Thanks for the "heads up", ADIOS600. I bought an unsold 2017 F model a year ago (my 85th bike) and also found the seat and suspension awful., which is due largely to my 135# weight. I went with a Corbin seat but added an AirHawk. Note that the AirHawk is subject to a bit of "tuning" as to the amount of air put into it. I was advised to go with about 1/3 the capacity and that has worked well enough. Corbin sportbike seats are very sturdy but hard as a rock. The shape is good, but Corbin never has learned (I've had 5-6 of them) that any seat that slants downward toward the front is patently uncomfortable. To my taste, a seat should be parallel to the ground, or slightly slanted downward toward the rear.

I ordered replacement fork springs from Race Tech and these are .60KG/mm stiffness. Almost there and I will pull the forks and replace the OEM 10 wt oil with 5 wt fork oil.

I initially ordered an Ohlins shock absorber, only to learn (after waiting several weeks) that they are no longer available. This from MotorcycleID. Revzilla also is out of them with no replacements known. Finally, I called Ted's Beemershop, a Wilbers distributor. Spoke to Ted Porter himself. He has 45 years of suspension experience, has been to the small Wilbers factory, which is in Germany {I liked hearing that) and spent a lot of time on the phone with me. He asked a lot of questions which answers were forwarded to Wilbers so the shock will be made in accordance with what I need, both as to springing and damping. Wait time is 4-5 weeks, so I'll likely have mine in 4 weeks. Cost of the Wilbers with adjustable damping is near $700. I will report on its suitability after getting and installing mine and putting several hundred miles on it.

I am a bit furious with Honda for cheapening a fine bike with lousy seat and rear shock. It costs not a penny more to make a better-shaped seat than the OEM board and the shock could have more adjustments for very little money. Honda also could have devised a better method of securing the rider's seat. What they came up with is horrible. I immediately switched to 30mm long stainless studs (LocTited in place) with flat washers, lock washers and nuts. Vastly easier to pull and remove a seat.

Sounds good mate. You will be over the moon with your shock. My man reckons spring was not too far out but majorly over damped. I made a sportsbike grab rail for mine to make it easier to put on the paddock stand, old tw*ts do that, when I press down on the rear it's like a lump of wood. People don't realize how poor the rear shock is, if they tried our bikes they would be surprised just how good the bike feels. My dealer said forget all the fancy shite treat yourself to a new shock and he was right.I agree totally on the seat issues. Look forward to your comments.
