Osiris by Tamarit Motorcycles

The Osiris by Tamarit Motorcycles is a custom Triumph Bonneville T100 built in Elda, Spain, the 91st creation from the Tamarit Workshop. Client-driven from concept to completion, it fuses Brat Style comfort with aggressive detailing into one breathtaking result.

The Concept

Project 91 began with a client who knew exactly what he wanted: a two-seater capable of carrying a passenger without sacrificing presence. Tamarit Motorcycles, known across Europe for reimagining Triumph classics, channeled that brief into a build that mixes relaxed ergonomics with sharp, purposeful aggression. The name Osiris references rebirth, fitting for a machine that takes a production Bonneville and transforms it into something entirely singular.

What Makes It

Every surface of the Osiris has been reconsidered. The engine block receives a nickel graphite plating, a technically demanding process that yields an almost liquid finish while protecting against corrosion. The speedometer is a Motogadget unit embedded flush into the tank for a seamless, minimalist silhouette. Motogadget also supplies the control knobs, turn signals, and the central control unit, which pairs with a smartphone app for full monitoring on the go. The chassis has been selectively cut to honour Brat Style lines while still accommodating the dual seat requested by the client. A custom floating side license plate holder maintains the required homologation angle without disrupting the clean rear profile.

The Build

The Kineo wire-spoke wheels are 16-inch units front and rear, machined from aluminium via a CNC pressure process and sealed for durability. Their 5/4 mm double-crimped spokes are lathed from high-strength steel and then galvanized. Straight handlebars give the riding position both comfort and visual authority. The Speedster exhaust runs the full length in ceramic baked-on black paint, a coating resistant to the sustained heat of the parallel twin. The rear LED light is embedded directly into the chassis, eliminating any bracket clutter. Seat posts and springs receive the same graphite nickel treatment as the engine covers, tying the finish language together from end to end.
