Founded in 1967, NCR was responsible for preparing Ducati’s competition machines for several decades, transforming stock Ducks into top-of-the-line racers. One of NCR’s most legendary works is undoubtedly the Ducati 900NCR that Mike Hailwood famously piloted to victory at the ’78 TT. Hailwood’s TT-winning machine not only prompted Ducati to release the wildly successful Mike Hailwood Replicas (aka “MHR”), but has also inspired countless one-off tribute and replica builds, such as this gorgeous example here.
This build started out as a 1984 Ducati 900S2, before the air-cooled, 864cc, four-stroke, 90-degree, SOHC, bevel-driven L-Twin received a very thorough overhaul. All gaskets, seals, and bearings were replaced, all eight rockers were resurfaced, and cams were timed to exact spec. The NCR replica also received some super trick bits such as a new gearbox, high-comp 87mm pistons (in new bored cast iron liners), and starter sprag clutch (sans flywheel) from Australia’s Veetwo, as well as heads made by Rino Caracchi of NCR, and an NCR style aluminum crankvent cap. The build also got magnesium valvecovers, new rubber mounted 41mm Dellorto carbs, new Sachse ignition, aluminum bevel tubes, refurbished crank with SS steel rod inserts, fullflow internal oil filtration using original filter, light straight-cut primary gears from Nova Racing (with new discs), and a conversion to run the starter motor from an undisclosed Yamaha 1100.
Wrapped around the well-sorted L-Twin is a top-shelf, lightweight chromoly chassis from Pierobon — an elite Italian chassis outfit. The new chassis weighs in at around 22lbs, and boasts a steering head that’s three degrees steeper than the stock unit. Paired with the trick chassis is a matching Pierobon wide chromo swingarm linked to a refurbished Öhlins shock with external canister. Up front is a 38mm Marzocchi M1R fork (that’s also been refurbished) slotted in CNC machined magnesium triples.
The rest of the hardware found on this example continues to personify the build’s spare-no-expense nature. The repliDuck now sports a quick-pull Domino throttle, Dyna minicoils with silicon wires, LiPo battery, custom electrical system (placed in the headlight with relays for hi and low beam), white face Veglia tach (calibrated and serviced) and MMB speedo housed in a CNC black anodized instrument panel (with idiot-lights), Works replica exhaust ceramic coated from Mario Sassi, all resting on a new set of replica Marvic Campagnolo rims. The braking hardware is now comprised of a new PS15 mastercylinder, Brembo P08 calipers, and (“Brembo-style) Leoncini discs up front, and a Brembo “twin-bleed” caliper (held via a magnesium caliper-bracket) reanodized with new seals, pistons and pads out back.
The trick frame and well sorted engine are adorned in genuine 1977 NCR bodywork and a carbon SS fairing and rear-fender. The controls are now made up of Menani lightweight clip-ons, and CNC’d replica NCR rear-sets with stainless steel balljoints. Every screw, bolt, and nut on the bike has been replaced by titanium hardware too. While the seller doesn’t cite any dyno figures, its probbaly safe to assume this NCR replica makes considerably more than the stock S2’s 80 horses (at 7,500 rpm). This build’s part-list is so lengthy that I recommend checking out the full ad—which also includes additional photos and a video of the replica running.
You can find this Ducati 900S2-based NCR replica for sale here on RaceBikeMart in Sweden with a price of $34,300 (or €30,000).
