If you’re thinking today’s Pierobon X85R is just some sort of Panigale in race bodywork with an aftermarket exhaust, you’re partly correct, but also missing an important detail. Hint: it’s red and is something you wouldn’t normally see on Ducati’s semi-monocoque superbike. A frame. Less obvious is the extended swingarm to improve the v-twin Pani’s somewhat unruly handling. All of it crafted to the highest standards from the best materials available, and the completed machine should be impossibly light: an X60R powered by Ducati’s two-valve engine weighs in at around 300lbs wet, depending on specification.
So why would you add a frame to a largely frameless bike? You’d have to ask Pierobon, although I’d suspect the frame has more flex to add a bit of feel to the somewhat feedback-challenged Panigale. But I’d trust them if I were you: located in Bologna near Ducati’s headquarters, they’ve been making frames, subframes, swingarms, and fuel tanks to their WSBK and MotoGP teams for over 50 years. As a sideline, they make a variety of trackday and racebike kits meant to accept Ducati’s two and four-valve engines. Be prepared for some sticker-shock though.
These are basically kits that include the frame, airbox, air duct, rear subframe, rearsets, and brackets for the electronics. To that base kit, you can add whichever suspension you want, using the original Panigale tank and swingarm. If you want, you can add beautifully-crafted, lightweight replacements from Pierobon, along with carbon bodywork that appears to be based on the Panigale. You’ll also need an exhaust, and other sundry bits. Boulder Motorsports, the folks selling this bike, have built a few of these in the past, and I’ve seen them at track days out here on the west coast. They’re minimalist and beautiful in the way that only pure racing machines can be. The seller includes the insane level of equipment that went into this one below.

Sound like your dream bike? Only one problem, the $110,000 asking price. Which, believe it or not, is probably well south of the actual build cost. Is it worth it? Considering the quality components, rarity, and performance, probably it technically is, although the performance is far beyond what most of us could hope to fully exploit and it doesn’t really have any value to collectors. Basically it’s a very, very expensive toy. But I know if price was no object, I’d want one.
