All Japanese sport bike seats are awful. You can play around with them and make some improvement; I did. However, in the long run it's best to concentrate on a properly formed seat and that is the Corbin. It's $343 USD plus shipping. In the USA, Corbin will ship only "signature required" to prove the buyer got the seat. This is expensive. Shipping from Corbin in California to central Texas was $36. Still, this is the 5th Corbin seat I've had going back several decades. They are very firm, but properly shaped and very well made.
No seat improvement will overcome the harsh, overly stiff (for us lighter folks) shock absorber. $600 for a fully-adjustable Wilbers, sprung to buyer's weight and riding style, is as necessary as the upgraded seat. Not welcome news, but figure on spending $1000 beyond the purchase price of the bike. Oh, another $15-20 on E-Bay will bring you a nice set of 30mm handlebar risers. No modification required to fit them. OEM cables are long enough, but you might have to remove the cable retainers behind the headlamp. Easy job and makes a big and inexpensive difference.
Oh, if you remove the seat, whatever the reason, do yourself a favor and get rid of those idiotic Allen bolts that hold it on. I had one **** of a time getting them to line up with the threaded holes in the frame. Cross thread those holes and you'll be very unhappy. The solution I used was to get threaded rod (I believe it's 5mm x 1.0 pitch threads but others please write to correct that if I'm wrong). Cut two 30mm lengths of this threaded rod and (Blue) loctite each in to the threaded holes in the frame. Use a Nylock nut of the correct size and thread pitch and a washer to secure the seat to the studs. It is very easy to mount the seat this way any time you remove it. You'll need to carry a 10mm open end wrench with you to remove the seat when traveling.
