Whether you’re restoring a vintage YZ or replacing a worn‑out saddle, this seat provides the comfort, grip, and reliability riders expect from Yamaha parts.
Key Features & Specifications
OEM‑Grade Construction
The 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 is built with high‑quality materials that match the original factory seat. The foam density is tuned for motocross demands, providing support during hard accelerations and jumps.
Perfect Fitment
Designed explicitly for the YZ250F (1998‑2002), YZ400F (1998‑2002), and YZ426F (2000‑2002) models, this seat aligns precisely with the stock seat frame and mounting points. Riders don’t need to modify any components before installation.
Durable Cover Material
The seat cover on the 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 resists abrasion and tearing, even in aggressive riding conditions. The texture also offers excellent grip between the rider and bike, improving control in corners and rough terrain.
Exact OEM Part Number
This seat carries the Yamaha OEM part number 5SF‑24710‑00‑00, ensuring authenticity and compatibility. For owners restoring their bikes to original specifications, this precision‑matched part is a valuable asset.
Performance & Riding Benefits
Comfort for Extended Sessions
The 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 uses foam that balances softness and support. While motocross seats are inherently firm compared to street bikes, this complete seat helps reduce fatigue during long rides or back‑to‑back laps.
Improved Grip
The seat cover’s textured surface offers grip that helps riders stay stable during aggressive riding. Whether cutting berms or launching over jumps, the 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 gives confident traction where it matters most.
Authentic Yamaha Feel
Because this seat is an OEM replacement, riders experience the same feel and contour as the original equipment. This consistency is important when maintaining the bike’s handling and ergonomics.
Installation & Fitment Guide
The 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 installs using the factory mounting points and hardware. Installation requires minimal tools and mechanical experience:
-
Remove the old seat by loosening the rear bolt and sliding off.
-
Align the new seat with the seat frame.
-
Tighten the mounting bolt to manufacturer torque specifications.
-
Check that the seat is secure and stable before riding.
Comparing with Related Seats
Aftermarket Gel Seat Covers
Some riders upgrade with aftermarket gel seat covers for added comfort. While gel covers improve cushioning, they often don’t match the exact contour and fit of the 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00. An OEM seat provides precise fitting and consistent performance.
Seat Foam Replacement Only
Replacing just the foam can be cheaper, but it often means reusing a worn seat cover. In contrast, the 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 offers a full rebuild with foam and cover, ensuring long‑lasting result and improved longevity.
Universal Motocross Seats
Universal seats can fit many bikes but lack the specific mounting design and contour optimized for Yamaha YZ models. The OEM 1998‑2002 Yamaha YZ250F YZ400F YZ426F complete seat 5SF‑24710‑00‑00 ensures perfect fitment and avoids modification hassles.
