SANYUMOTO Adjustable Rider Backrest for Harley Touring One-Piece Slotted Seats — Black, High-Rebound Foam & Multi-Position Adjustm

SANYUMOTO Adjustable Rider Driver Backrest is a detachable, ergonomic lumbar support designed to fit one-piece slotted seats on many Harley-Davidson Touring models from 1997–2026.

This rider backrest delivers tunable support and a factory-like fit for compatible Harley Touring bikes. Built with high-rebound foam and a flexible torsion-spring mechanism, it balances comfort, durability, and ease of installation. The cushion folds forward for passenger access and offers multi-directional adjustment to suit different rider heights and seating preferences.

Which Harley models will this backrest fit?

The SANYUMOTO backrest is engineered for Harley-Davidson Touring models equipped with one-piece slotted seats. It covers a broad range of Street Glide, Road Glide, Electra Glide, Road King and CVO variants produced across multiple years, but it does not fit Trike models or certain 2021-and-later FLH configurations.

• Compatible: Street Glide, Road Glide, Electra Glide, Road King, Ultra and many CVO Touring models.
• Year range: Broad coverage from late 1990s through mid-2020s for one-piece slotted seats.
• Not compatible: Trikes, 2021+ FLH models with different seat systems, and two-up specific seats.

How does the backrest adjust to my riding position?

Adjustment is simple and flexible: the bracket provides vertical and horizontal mounting positions so you can fine-tune lumbar placement. Riders can move the pad up or down and fore or aft using the multi-hole pattern to find a comfortable pressure point for long-distance riding.

• Three vertical positions for height variation.
• Four horizontal options to control distance from the seat.
• Tool-accessible hardware for quick on-bike changes.

What materials and features improve comfort and longevity?

The cushion is filled with resilient, high-rebound foam that returns shape after weight is removed, reducing bottoming out on extended runs. Instead of conventional tension springs, the mount uses flexible torsion springs that resist loss of elasticity and extend service life while allowing the pad to fold forward for passenger entry.

• Soft high-rebound foam for consistent lumbar support.
• Flexible torsion-spring assembly for durable folding action.
• Durable vinyl cover and reinforced mounting hardware for everyday use.

How easy is installation and is it a direct replacement part?

Installation is designed to mimic factory mounting so the backrest fits like an OEM accessory on approved seats. It replaces several Harley part numbers and aligns with the slotted seat hardware pattern, making installation straightforward for most riders with basic tools.

• Designed to replace specific Harley P/N references for one-piece slotted seats.
• Simple bolt-on installation with clear mounting holes and hardware access.
• Folds forward to maintain passenger access without removal.

Who is this for: The SANYUMOTO Adjustable Rider Driver Backrest is aimed at Harley touring riders who want a comfortable, adjustable lumbar pad that closely matches factory fitment on one-piece slotted seats. It’s a solid option for riders who log long miles and need better lower-back support while retaining passenger convenience and durable, reliable hardware. Confirm seat type and model year compatibility before ordering to ensure proper fit.
