Pierobon X85R

Built to be a chassis kit for Ducati owners with an extra Superquadro engine laying around (899/959/1199/1299), the Pierobon X85R takes this potent street bike and makes it into a track weapon.

The concept starts with a steel alloy (25CrMo4) trellis frame, which includes aluminum alloy blocks (EN AW-6082 T6) that have been CNC shaped into lateral plates. The resulting frame can be built out with either a single-sided or double-sided swingarm.

For those interested, the base kit includes the frame, airbox, air ducts, rear subframe, foot pegs, and lateral electronic holders.

That should be enough to get most builders started, though Pierobon also offers its own fuel tank and swingarm designs (the stock units work with the kit though). The result is a truly unique motorcycle with one of the best v-twin engines ever produced.

Pierobon doesn’t stop there though, as the Italian firm has also created its own winglets for the superbike, which work both on the stock fairings or on Pierobon’s own carbon fiber units.

Pierobon says the winglets produce 6kg of downforce at 150 km/h, and 17 kg of downforce at 250 km/h. This means less electronic intervention (reduction in power) for wheelie control, and a higher load on the front tire at the beginning of high-speed braking.

Other items of note are the ultra-light rear subframe made out of aluminum (700g / 1.5 lbs) and the adjustable headstock angle. As usual, the work by Pierobon is stunning, and the bike’s madden racing voyage saw a race win at the Barber Vintage Festival.
