Yep, I know about the suspension adjustments - that's the first thing I did on it - set it to the softest setting. I've also added a Butt Buffer seat pad to the seat.
Unfortunately, the local roads here have been destroyed by the equipment and trucks that are constructing the hundreds of large wind turbines in our local hills. So I'd have to ride standing all the time because of so many pot holes, ruts, and strange curvy deep gouges on the roadways.
I've added the electric grip warmers to my S250 to help keep my hands warm when I'm riding. And I bought a Battery Tender to help keep the battery charged. I alternate riding my S250 & my Burg 400 and ride both of them at least once a week for at least half an hour each.
Actually, even with smaller wheels, the Burg handles very well and is very manueverable. The suspension and seat are much much better than the S250's, so it's much more comfortable to ride. The Burg is stable on interstates and freeways, although it gets blown around more than my Silverwing did.
I also like & need the extra power for the times that I ride up in the Sierra Nevada Mts along Eastern California - some of the inclines can be challenging. It was a breeze on my Silverwing but my Burg occasionally struggles. I'm anxious to see how the S250 does. It is fun to ride.
