Description
For Triumph Bobber riders demanding superior comfort without sacrificing the aggressive solo-seat aesthetic, Motone’s King Cobra represents four years of development focused on eliminating the notorious discomfort of the stock Bobber perch. Featuring injection-molded high-density foam shaped specifically for extended rides and a 4mm steel pan that eliminates the flexing common in thinner seat bases, this diamond-stitched replacement transforms multi-hour journeys from endurance tests into sustainable cruises.
Key Features
4mm Heavy-Duty Steel Pan Construction
Unlike the stock Triumph Bobber seat using 2-3mm stampings prone to flex under rider weight, this reinforced 4mm steel pan provides rigid structural support that prevents mid-ride sagging and maintains foam compression consistency. The increased thickness eliminates the “hammock effect” where thin pans bow downward, creating pressure points at seat edges. Powder-coated finish resists corrosion from moisture infiltration through stitching, extending service life in humid climates and preventing rust-through that compromises cheaper aftermarket seats.
Injection-Molded High-Density Closed-Cell Foam
Engineered using closed-cell polyurethane foam injection molding (not cut-and-glue methods), the seat achieves graduated density zones—firmer base layer for structural support, softer top layer for initial comfort—that distribute weight across a larger surface area than the stock seat’s 185cm² contact patch. The closed-cell structure resists water absorption, preventing the soggy compression and mildew issues affecting open-cell foam seats after exposure to rain. Density specification at 55kg/m³ provides the optimal balance between support and comfort for 80-95kg riders during 2-4 hour sessions.
Marine-Grade Diamond-Stitch Vinyl Cover
Upholstered in marine-grade vinyl engineered for saltwater exposure resistance, the cover material withstands UV degradation, temperature extremes (-20°C to 65°C), and petroleum product contact without cracking or color fading. The diamond stitch pattern isn’t purely aesthetic—it creates surface texture that prevents rider slide-forward during aggressive braking while enhancing ventilation compared to smooth vinyl. Double-stitched seams use bonded nylon thread (350% stronger than standard polyester) that won’t rot from prolonged sun exposure.
Direct Bolt-On OEM Fitment
Designed as a direct replacement for the stock Triumph Bobber seat pan, using OEM mounting point locations and hinge bracket geometry. Installation requires zero modifications—simply remove the four T30 Torx bolts securing the stock seat, transfer the hinge assembly to the Motone pan (reuses stock hardware), and bolt into place. The seat latch mechanism integrates with the Bobber’s factory locking system without requiring additional brackets or spacers. Fits both standard Bobber and Bobber Black models from 2016-present.
Ergonomic Profile for Extended Comfort
The seat profile drops rider position approximately 15mm lower than stock while widening the seating surface by 25mm at the midpoint, distributing load across a larger area and reducing pressure on the sit bones (ischial tuberosities). The nose taper narrows sufficiently for feet-flat stops at traffic lights (critical for shorter riders), while the rear kick-up prevents rearward slide during acceleration. Designed specifically for solo riding—pillion accommodation not recommended due to optimized single-rider weight distribution.

Installation Note: Remove the stock Triumph Bobber seat by unscrewing four T30 Torx bolts located under the seat pan (two front, two rear). Transfer the stock hinge assembly to the Motone seat base using the existing mounting hardware—ensure proper alignment before tightening to prevent binding. Test the latch mechanism before riding to verify secure engagement. For riders exceeding 95kg, consider adding a gel pad insert for additional cushioning during rides beyond 2 hours. The marine-grade vinyl requires no special care—clean with mild soap and water, avoid petroleum-based cleaners that may degrade protective coating.
