Bonneville Profile Seat — Honda CB350 / GB350C

Designed for Classic Roadster Styling & Two-Up Comfort

The Saddle Crafts Bonneville Profile Seat for the Honda CB350 / GB350C combines timeless British roadster proportions with targeted ergonomic refinements. Unlike flat vintage bench seats, this saddle features a subtly contoured rider pocket for improved lower-back and hip support, paired with a deliberately broadened rear section that enhances pillion stability and comfort. Framed by crisp perimeter piping, it delivers a balanced heritage look without sacrificing long-ride practicality.

Why It’s Different

• Contoured Bonneville Silhouette: Preserves the iconic Bonneville line while introducing a subtle rider dip that keeps you planted and supported.

• Broadened Pillion Deck: Widened rear seating platform eliminates the narrow taper of standard retro seats, providing substantial surface area and support for your passenger.

• Distinctive Perimeter Piping: Contrasting or matched edge piping traces the saddle's geometry and highlights its classic proportions.

• Fiberglass Structural Base: Built on a lightweight, rigid fiberglass seat pan rather than heavy stamped steel or flexible plastic, ensuring lasting chassis alignment.

Engineered For

• Model-Specific Fitment: Developed specifically around the frame rails, fuel tank junction, and rear fender geometry of the Honda CB350 / GB350C.

• Solo & Two-Up Touring: Balanced ergonomics that support daily commuting, weekend highway runs, and comfortable passenger travel.

• Heritage Roadster Builds: Elevates the vintage character of the CB350 / GB350C with authentic custom coachwork.

Crafted With

• Marine-Grade Technical Vegan Leatherette: Supple, UV-stable, and abrasion-resistant animal-free upholstery.

• High-Density Sculpted Polyurethane Foam: Hand-shaped to create the supportive rider contour and wide pillion platform.

• Lightweight Fiberglass Seat Base Plate: A rigid, rust-proof composite seat pan beneath the upholstery for a direct bolt-on fit.

• Defined Piping & Seam Detailing: Heavy-duty industrial stitching and structured edge piping that hold their shape over time.

Water Resistance & Care Note

• Plain vs. Stitched Patterns: While Plain upholstery covers are water-resistant, seats ordered with stitched surface patterns (Stripes, Double Stitch Stripes, Diamond, Double Stitch Diamond)—or customized with embroidered logos—can absorb water through the needle perforations during rain or washing and take time to dry depending on weather conditions.

• Mandatory Protection: Always use the complimentary Waterproof Seat Cover included with your order when riding in the rain, parking outdoors in wet conditions, or washing your motorcycle.
