I guess if you read it properly its the SDR seat not the standard seat...
I had a standard SD for 18 months and i found this seat to be superb for all day or a week in the IOM.
Replaced the 07 SD with a late 08SDR and the seat is a plank....I fitted the ergo gel seat from KTM powerparts and a 200 mile trip later was thinking what a waste of money.....given time however the seat has changed.
I went to a well respected seat maker in Preston who could refinish and fit a gel pad to the standard plank but my suspicion’s were aroused when he said don’t expect miracles overnight, the gel pads take time to mould to your crevice and given time become more comfy.
I decided to take the gel seat off ebay and stick with it...2 years on it is alot better but not great, it also has a big downside if you track day or fast change of direction in that it is very grippy which don’t help in this situation.
I have done a conversion to standard seat with rear pegs but bought the ergo gel seat for a big saving over standard ..most people say no difference so i had only money to save, this seat is by a long way more friendly to the derrière and i get to carry a pillion / day pack / ext.
The gel standard seat to me is only used for a month or two a year so I don’t have any real reference other than being really comfy.
The standard SDR seat i used if i am doing the journey 2 work (12miles each way) as it has a good fast twisty road section and the seat helps to slide around.
So i guess from reading this back to myself....the answer is complicated, and to add another spanner in the works, when i first bought the SDR I felt so uncomfortable i bought a pair of cycling shorts with a pad that easily fitted under my leathers for the 600 mile brake in and service period and I had no trouble at all. The Best of both worlds , slidey seat with a gel pad onboard so to speak.
My RC8 seat feels about as comfy as the SDR gel seat but being wider just seams to work fine at any distance i have spent on it.
