The Ultimate In Design and Performance

Giotto is now available in the U.S! You can order Giotto as a complete build. Manufacturing time can take up to three months. Contact us about your future build.

Giotto by Box39 is based on the Harley-Davidson VRSCDX engine and frame. Each motorcycle is hand built from the ground up at our shop in the U.S. With a number of different options, we can make every motorcycle unique to its owner.


Giotto uses the latest CNC technology to produce bespoke parts designed by Box39. From the single-sided swingarm to the individual billet components, everything has been re-imagined, designed, and created by Box39 technicians. Custom components are machined from solid billet over an intensive 500-hour process.

In true bespoke fashion, each motorcycle is created according to the individual owner’s personal taste. The team works with each client on every design element. The client then tailors the textures and finishes to create their own unique Giotto motorcycle. This is an exquisitely detailed motorcycle.

Custom Components | Manufactured in-house

In addition to the hundreds of parts manufactured in-house, Henne Co. also works in partnership with carefully selected brands.

Giotto uses the liquid-cooled Revolution 60-degree V-twin, displacing 76.1 cubic inches (1247cc), with electronic sequential port fuel injection. On tap is 125 hp at 8250 rpm, and 85 ft/lbs of torque at 7000 rpm. A slipper-style clutch allows for aggressive riding, and the inverted forks and twin shocks come with updated settings for superior handling.

Rear Suspension
Giotto comes with a proprietary single-sided swingarm made by Box39 and Platinum adjustable air-ride suspension.

The 21 —Ö 130 mm front and R18 —Ö 300 mm rear custom wheels are made from milled aluminum to minimize unsprung weight and enhance ride and handling characteristics.

Giotto‚Äôs brakes feature dual full-floating front rotors to ensure optimum brake-pad-to-rotor contact, and a single Standard Solid Mount Wave¬ģ Rotor by Galfer on the rear wheel. Every high-quality Galfer-patented Wave¬ģ rotor is made from a proprietary mix of virgin high-carbon laser-cut (never stamped) 420 stainless steel. Beringer six-piston radial calipers are ready to meet any application. These billet calipers are made from an aeronautic aluminum, and have been developed with the knowledge acquired from Beringer‚Äôs many years of competition experience.

Assembled at Henne Co.’s Fort Lauderdale, Florida, facility, each Giotto is built to order. The entire process takes 90 days or less from the beginning of work to the completion of the motorcycle.
