Inside the Honda RC213V MotoGP Prototype

MotorcycleUSA Staff | April 17, 2015
Repsol Honda’s full factory RC213V MotoGP prototype is the best of the best in the realm of sportbikes. It’s the motorcycle most racers aim to compete with and the one teams and mechanics hope to one day turn a wrench on. During this past weekend’s Red Bull Grand Prix of the Americas we snuck inside the Repsol garage and snapped off a couple pics of its unobtainable hardware that money can’t buy.

The Termignoni-made titanium exhaust is purely a work of art. The welds and bends are intricate to say the least making for a compact yet power-producing pipe. Honda claims the RC213V is capable of pumping out over 234 horsepower.
Loaded with rocker switches the RC213V employs a bevy of electronics and rider aids that can be manipulated by Marquez during a race. This allows him to modify settings based on fuel load, tire wear, or the condition of the track’s surface.
Like the competition, the RV213V by Honda employs a pair of carbon fiber front brake discs. Contrary to more traditional metal rotors, these discs rely on a very high degree of heat for optimum operation reaching temperatures in excess of 750-degrees Fahrenheit.
The carbon fiber discs are pinched by a pair of polished and CNC-machined calipers from Brembo. Each caliper is machined from a solid piece of aluminum for reduced flex during use. Also of note are the holes drilled into each piston presumably for more effective thermal dissipation.
Unlike a production sportbike the RC213V employs a dry clutch. This set-up reduces weight and parasitic power losses from a conventional bathed-in-oil ‘wet’ design. Also of note is the low and centered location of the 5.28-gallon fuel cell just above the Ohlins shock absorber.
The Honda RC213V employs a giant braced swingarm with forged magnesium rims by Marchesini. This season marks the final year of the 16.5-inch wheel combo with the series going to a more production-based 17-inch specification as Michelin prepares to take over as the spec-tire provider.
