Yamaha SR 400 Yard Built -GibbonSlap- 2014 — Specifications

If the standard SR 400 is already an icon of mechanical minimalism, this version named GibbonSlap, imagined by the Danes Wrenchmonkees with the help of KEDO, takes the concept in a frankly radical direction. We are no longer talking about a simple customization here, but a transformation that redefines the use of the motorcycle. The objective is clear: strip away the essentials to create a raw, almost utilitarian urban tool, disregarding aesthetic conventions.

The work is consistent and uncompromising. The transition to a single-seat configuration is not a stylistic choice, but a functional act. The space freed up on the frame is immediately colonized by a robust luggage rack, designed to accommodate handcrafted saddlebags. It’s a declaration: this SR 400 is made to carry things, to be used, not just to be admired. The large-section tires, the megaphone-shaped titanium exhaust, and the polished aluminum fenders give it a look that is both primitive and sophisticated. The matte black finish on the frame, tank, and forks is a total rejection of the usual chrome, an almost timid option that paradoxically forces the eye.

Technically, it remains faithful to the base: the 399 cc single-cylinder engine delivering 23 horsepower and 27.5 Nm of torque, a five-speed gearbox, and mixed disc-drum braking. The mechanics are unchanged, but the spirit is different. At €7,000, this transformation kit positions the GibbonSlap in a very niche segment. It’s far from the price of a new SR, and even further from the economy of a homemade customization. It's a product for the enthusiast who wants a unique machine, ready to use, without having to spend months in his garage.

Compared to a Triumph Street Twin or a standard Honda CB400SF, it offers no advantage in performance or versatility. It is less powerful, probably less comfortable, and its original tank limits range. But it is not competing with them. It speaks to those who seek an identity, a motorcycle that is an extension of their personality rather than a simple means of transport. The name GibbonSlap, taken from a knot used by old sailors, completes the creation, giving it a narrative, almost mythological character.

In short, this SR 400 Yard Built is a desirable object for a very specific audience: the urban rider who sees the motorcycle as a lifestyle accessory, a mobility and expression tool. It is not made for speed or long journeys, but for daily commutes with a defined style, to carry one’s literal and figurative baggage. It’s a courageous proposition, which sacrifices convention for attitude, and which, in this area, succeeds in its bet with a certain elegance.
