Seats

Foam & Cover Kit

Seat Concepts seats are constructed using a foam material that is a much higher quality than OEM seat foam. Their proprietary formula provides a more plush and active ride, while still offering the necessary amount of support. Their unique comfort shape maintains a similar contour to stock at the front of the seat so the rider’s legs are not spread farther apart, but tapers out towards the mid-point to distribute rider weight over a greater area.

These features combine to offer a custom seat feel, and provide greater enjoyment and increased range on a long commute, or Dual-Sport ride!

Check out the seat warmer we carry. Put this in before tacking your cover in place and keep yourself warm during even the coldest rides. Nothing like toasted buns to make a ride comfortable!

Available as a Foam and Cover Kit for OEM pan only.

Width:8.5" (216mm)
Height:Same as OEM
