SANYUMOTO Adjustable Rider Driver Backrest is a detachable, ergonomic lumbar support made to fit many Harley Davidson Touring one-piece slotted seats, giving riders customizable comfort and durable construction for long rides.

If you own a Harley Touring model with a one-piece slotted seat and want better lower-back support without altering the look of your bike, this rider backrest provides a factory-style replacement that’s easy to fit. It’s engineered with high-rebound foam, flexible torsion springs, and a multi-hole adjustment system so you can dial in the position that suits your riding posture. Before ordering, confirm compatibility with your specific Harley year and model to ensure correct fitment.

Will this backrest fit my Harley Touring model?

The SANYUMOTO backrest is designed for Harley Davidson Touring one-piece slotted seats across many Street Glide, Road Glide, Electra Glide, Road King and CVO variants from 1988 up to the mid-2020s. It is not compatible with trike models, 2021-and-later FLH models that use a different mounting, or two-piece seats. Always compare your bike’s seat type and model year to the listed compatible vehicles before purchase.

• Compatible with many Harley Touring Street Glide, Road Glide, Electra Glide, Road King, and CVO models
• Not for trikes or 2021-later FLH models and not for two-up seats
• Check the product fitment list for exact model-year matches

How does the adjustment system improve comfort?

The backrest offers vertical and horizontal adjustments so you can position the pad for proper lumbar contact and relaxed shoulder alignment. There are three vertical holes and four horizontal positions to fine-tune reach and height, making it easier to reduce fatigue during extended rides without professional modifications.

• 3-hole vertical adjustment for height control
• 4-hole horizontal adjustments to change distance from the seat
• Simple hand adjustments for on-the-road tuning

What materials and features make it durable?

This backrest uses a high-rebound foam core that keeps its shape ride after ride and a cover designed to withstand weather and abrasion. Instead of standard tension springs, built-in flexible torsion springs preserve elastic performance longer and allow the pad to fold forward for passenger access without stress on the mechanism.

• High-rebound foam for consistent lumbar support
• Flexible torsion springs for longer-lasting elasticity
• Folds forward for easy passenger entry and convenience

How straightforward is installation and replacement?

Installation is intended to provide a near-factory fit for compatible one-piece slotted seats, replacing common Harley part numbers without custom mounting. The bolt-on style and fitment design mean most owners can install it with basic tools and minimal effort, but checking the model compatibility beforehand prevents returns.

• Factory-like fit for compatible one-piece slotted seats
• Replaces several Harley OEM part numbers for direct substitution
• Basic tools required; straightforward bolt-on installation

Who is this for: Motorcycle riders who own compatible Harley Touring one-piece slotted seats and want a removable, adjustable rider backrest that improves lower-back comfort without permanent bike modifications. It’s ideal for long-distance riders seeking ergonomic lumbar support, those replacing worn OEM pads, or owners who prefer a durable aftermarket option that matches factory aesthetics.
