So Seat Concepts was nice enough to send me a CRF450X seat kit for the Christini! The Seat Concepts seat kit is a very nice piece. It contains the new seat foam, the cover in your choice of coverings, and very good instructions. I those plain black vinyl, but you can also get Carbon look and gripper, see their website. There is also a link to a video on installing the seat kit, I actually found two on YouTube, one on a KLR and one on a KTM. These really helped too.
Here is a shot of the stock seat on the bike. I needed to pull the cover of anyway because one of the seat brackets was starting to come loose. When I removed the cover, I found out why. Even though the seat base was molded with little spot face type flat areas for using backing plate washers behind the pop rivets used to attach the brackets, they didn't use any?! The rivets, not surprisingly, started to pull through the plastic seat base.
Below you can see the seat base in the center, the stock foam above, and the Seat Concepts Comfort foam for a CRF450X below. You can also see the Christini seat is virtually identical to the CRF450X seat base. I also re-attached the brackets using new rivits and backing plates, which should hold much better. The Christini did not use any adhesive to hold the stock foam to the base, as most bikes do and SC recommends.
Besides the spray adhesive to attach the foam to the base, you'll need a small screw driver to pry off the staples holding the stock cover on. You'll also need a stapler, probably a pnuematic, as SC uses, or an electric like I used to attach the cover. I am not sure if a manual
stapler would be strong enough to get the staples fully in? Anyway, it is a pretty simple process and you should finish very quickly.
I did find the "Comfort" seat to be a little wide in the center for me, so I trimmed it just a little, creating what I would call a Sport/Comfort seat. The Comfort being their wider version, while the Sport is only slightly wider than stock. And here is the finished product installed, which I am very happy with. The foam and the padded seat cover seem much more comfortable, but I'll have to verufy that in the future. Thanks to Seat Concepts for a great product!
