lots of good info.
the stock seat is useless other then looks. it provides zero grip and it's shape (as stated above) slams you into the tank (and not to beat a horse that's 10 foot below at this point...) puts your inner legs very close to the rear cylinder (which is where the majority of the heat issue comes from).
In my opinion:
this should be your 1st mod by far. I tried both the comfort and race seat.
-Comfort seat (for me and my posture and size) too high up and made it difficult for me to keep my weight on the pegs.
-With that, it also left me feeling "out of the bike" as apposed to "in" the bike (the only benefit to the low stock seat)
Race seat:
- This option changed the bike
- Tons of grip
- Perfect height for my inseam and just enough to keep you off the rear cylinder
- My favorite aspect of the seat is how flat it is in the back. it allows you have a real flat and stable platform to more around a bit more while retaining enough seat under your can
My choice was the race, but either seat (i feel) was what this bike was developed with.
it takes two seconds to swap the seat, so if you have the option to try both at your dealer, I couldn't encourage it more. either seat is worth every penny. hope this helps.
