I bought this P200E with this King & Queen seat on it. I know it may look a little funny but it is much more comfy than my other stock P200E.
I'm 6'3" 225lbs and have to sit far back on the stock seat past the bar under the cover. Ride is a bit rough and you bottom out over bumps.
With the King/Queen seat I sit a little high almost on the ridge and the ride is really more comfortable and it doesn't feel like I'm right up against the leg sheild which makes the rear brake akward to operate.
It also feels like I can control this scooter much more than the stock. I want to take my test at the DMV but it has a polini exaust and I don't know if they will accept it with this exauhst modification.
