P.M. Motorbike sharpens the fangs of an aging Monster…
When Ducati introduced the Monster S4 in 2001, it was more than the next evolution of the company’s iconic air-cooled factory streetfighter — it was a revolution. For the first time, the Monster received a liquid-cooled eight-valve superbike engine lifted from straight the Ducati 916 — fuel-injected, of course — and all S4 models boasted fully adjustable suspension, a dry clutch, and Brembo brakes.
Though the 90º V-twin engine had been detuned from superbike spec, it still made 101 hp and 68 ft-lb of torque — the first Monster to break the 100-hp mark. Once conceived as a basic naked roadster — the original design brief called for a modern equivalent of Brando’s Triumph in The Wild One — the Monster had become a much sharper tool, and the world took notice:
“More punch than a bare-knuckle fist fight and the handling to match — Ducati’s S4 Monster is armed, dangerous and on the prowl…” –Bike Sales
While the S4 was revolutionary at the time, the model is now more than 20 years old — quite long in the tooth.
Recently, we got in touch with Pier and Marco of Italy’s P.M. Motorbike — a duo who’ve joined forces to realize the dream of opening their own workshop to build “unique, personal, and exclusive specials” for their customers. When one of their clients and friends brought them this aging Monster, they were given full creative freedom to sharpen its teeth:
“The idea was to make an older motorcycle absolutely current, elegant, sporty, proportionate, and with the aggressiveness that distinguishes it.”
This S4 has been completely transformed. Up front, the 43mm USD Showa front end was re-anodized and fitted with a carbon fender. Out back, Pier and Marco swapped in the single-sided swingarm from a Ducati 748, along with an S4R rear wheel, S4Rs pegs, shortened subframe, and custom rear cowl.
On the performance front, the bike is now running an electronic quickshifter, free-flowing intake, and a trick QD exhaust system. Little details abound, such as the LED lighting and carbon engine covers, and the chocolate / gold livery is both unexpected and oh-so-right.
While this Monster manages to look both elegant and aggressive, it isn’t just for the eyes — it’s leaner and meaner, too:
“The starting weight was 193 kg, we took off almost 20kg. Starting power 101 hp; we brought it to 112 hp.”
