For the last month or two, I've been switching back and forth between the WR250R/X Spiral Step Seat and the WR250R/X Seat Concepts Seat (Low Foam Version) on both my WR250R and my WR250X. Here are my thoughts on the two seats...
Installation:
Installation of the Spiral Step Seat, which is a complete seat, takes just a minute or two... you just take the two bolts holding the stock seat out, pull it off the bike, put the Spiral on and put the two bolts back in... simple as that. The Seat Concepts Seat comes as a seat kit, which includes their seat foam and cover. You have to install it on your stock seat pan before you can bolt it on the bike. Most customers seem to do it themselves, but some may choose to have a local upholster do it.
Overall Impressions:
The Spiral Step Seat lowers the seat height about 1 inch, which is great for riders who have issues with the tall stock seat height. The seat works fine for shorter rides (around 100 miles) and, to me, it is slightly more comfortable than the stock seat. For longer rides I definitely prefer the Seat Concepts Seat. The Seat Concepts with low foam is about 3/4" lower than stock, is wider (9 3/4" at its widest point), and has slightly softer foam. The combination of softer foam and wider seat surface make it really comfortable, and ideal if you put a lot of miles on your bike each ride.
The Bottom Line:
If you mainly do shorter rides on your WR250R/X and need to lower the overall seat height, the Spiral Step Seat will probably work fine for you. It's super easy to install and you don't need to tear apart your stock seat to install it. If you do a lot of long rides on your WR250R/X and want a lower, but wider, seat, the Seat Concepts Seat with low seat foam option is the way to go....just keep in mind, you need to install it on your stock seat pan.
