HOGS OF WAR. Anvil Motociclette’s ‘Warthog’ Ducati S4R Tracker

No matter how strong your nationalistic tendencies it’s almost impossible to argue against the fact that Italy has produced the world’s greatest artists. Not just the likes of Michelangelo and Caravaggio but polymaths Da Vinci and Galileo who were experts in so many areas it’s impossible to count. What these men also possessed was an unmistakable madness and willingness to transgress society’s norms that are qualities our modern renaissance men of Anvil Motociclette not only share but are deeply proud of. So it should come as no surprise that San Marco and Phonz found their inspiration for this build in an immense and dusty abandoned factory that serves as a mausoleum for a century old motodrome. It’s rolling art with superbike levels of performance, a Ducati Monster S4R that now goes by the name WARTHOG Mille.

Serving as the basis for the build the early 2000s S4R was one of the first machines in the now popular Super Naked class that packs race derived powerplants into stripped down unfaired machines for the ultimate in raw unadulterated motorcycling experience. As the build was intended to be the first in a new wave of Anvil bikes they needed an understanding customer and just the right fellow turned up at the shop as the boys explain, “When we started designing this special, we had few customer limitations, leaving plenty of freedom both in design and in the motorcycle concept, the only guidelines we had given was to create a very aggressive bike with a unique design and delicious performance.”

Simple instructions that allowed for the ultimate prerogative to throw off any and all restraint and let the design reveal itself on the canvas. Two things they knew they wanted to achieve were to move past “classic” motorcycle shapes and create a clear divergence from past Anvil builds. But first they had to strip the Monster down to its skeleton; the signature tank, comfortable seat, classic headlight and fairing all gone and left lying on the floor till just the steel trellis chassis and angry L-twin motor remained. From here the signature Ducati frame, its lines and angles, those scalene triangle shapes would heavily influence the path forward.

Working with Officine Italiane Zard on a number of components of the bike the most drastic change comes from the bodywork that totally transforms the Ducati from smooth lined machine into sharp-edged fighter. The fuel tank is in fact just a cover for the air box and while at first it might seem thrown together if you look closely you’ll notice the very deliberate lines. Untold hours went into crafting the sharp edges that still allow the tank to follow the curved lines of the frame, the angles in the tank piece mimicking those of the trellis and the welds left raised like brush strokes on an oil painting.

The single piece body work neatly transitions down into the seat base where extra supports are welded in to meet the chassis. Before following the lines of the frame rearward, wrapping around the final edges to create a signature tail piece to match the tank. It’s here that the fuel is actually stored with a neat alloy fuel cell crafted to sit under the seat with the filler cap on top of the tail. Being a fuel injected engine this required lines to be run rearward and a blacked out external pump gets the juices flowing without compromising the limited internal capacity.

“The saddle is in black leather, from old sports seats, we made it more slender thanks to the tapered stitches, mirrored in the black colour graphics that decorate the tank,” the Anvil lads affinity for matte black and classic leather still a part of this new style of bike building. Their classic contrast of raw metal and the dark hue isn’t lost either with the frame given a fresh black coat and the gorgeous Ducati tubular single sided swingarm taken back to bare metal. That theme is meticulously maintained throughout, with the square LED headlight and its mount a mix and match of the two distinct looks.

The suspension also gets the treatment; the impressive USD Showa forks were totally disassembled and rebuilt for the job. The triple clamps have had their paint stripped and then media blasted to give more of that worn metal feel, while the legs were painted black and the stanchions given a hardened gold to match the braking hardware. All of which comes in the form of totally overhauled Brembo components, 320mm discs on the front with four piston calipers and a two piston caliper doing the job out back. Lightweight Marchesini wheels deliver in the quality stakes and the exceptional Pirelli MT06RS rubber provides superbike like grip on just about any surface.

Which you’re going to need when you remember that the S4R is no ordinary Monster with a two valve air-cooled engine. Taken straight from the 996, the four valve engine uses 20 years of R&D to pack the ultimate superbike punch into this weapon for the street. But Anvil wasn’t satisfied with what the Ducati engineers had delivered and as well as giving the motor a visual makeover they also sought out more ponies. Zard came back to the table with one of their incredible exhaust designs and the expanded airbox design feeds all new filters. With the hardware in place the Marelli EFI has been remapped to suit and you have genuine 280km/h potential.

That takes some serious steering so rather than fit clip-on bars and swanky pieces San Marco and Phonz wanted to give their customer maximum control. This is achieved with “wide handlebars as if it were two devil horns, because of the devil it is, the result we wanted to create on the WARTHOG is a super naked exasperated both in cycling and in performance,” enthuse the boys. The black bars are from the Tomaselli catalogue and have been fitted only with the bare essentials, levers and reservoirs from the Brembo catalogue. Bear trap pegs make sure the rider’s feet stay where they’re meant to be and all said and done this radical ride is set to attack the streets like its name sake with devastating consequences and absolutely no victim spared.

    The whole idea with the lines of the trellis frame continuing..genius,but the bike looks still too heavy for a tracker. The exhaust is way too big ,even when its well made and the swingarm too long…everything doesent look right to me.
    Anvil bikes are usually point on but this isn’t, sorry.

    • Flying W

      Yeah, the guy in the video looked like he was a bit worried about dropping it. Slippery surface, so understandable, but it only added to that impression of heavy and unwieldy.

    • To be honest, I called it a tracker. I’m not sure Anvil ever used that word, though…

      • guvnor67

        I think with perhaps a lower bend Renthal handlebar or suchlike it’d be getting closer to Street fighter territory. It’s lines are quite aggressive and power to weight would surely be in the “arms-out-of-sockets” category?!

        • Yes indeed. I was also toying with the idea of calling is a Street Tracker, Street Fighter or just ‘naked’. I guess the lack of indicators means it’s not really a ‘street’ anything, tho.

          • guvnor67

            I remember back in the UK if a bike was pre- (1988?) it didn’t need indicators, electric horn etc. Not sure what the rules are in Italy for modern machinery, but hand signals used to work for me!!! Plus, we use to rip “unwanted crap” off just about anything, y’know, for weight reduction and aesthetics!!

          • martin hodgson

            Despite appearances I’d say this bike weighs around 175kg, they were around 193kg from the factory. That makes it 80kg less than a Sportster and at least 20kg less than a lot of other bikes that are made into trackers and this thing packs a hell of a lot more horsepower. Much like the Roland Sands Ducati Tracker (although that had another 60hp). With the right rider on board this thing would do serious lap times, especially on a big track. So hard with some of these bikes to really fit them into any category though… which imo is a good thing for a bike like this. It just is what it is… bad ass!!!

    Amenable human interface.
    Without it you only have something that sits in the garage while you pay insurance and taxes on it.
    Having ridden a friend’s Buell S1 I can tell you that seat would ensure this would be the low mileage vehicle at my place.
    Not a huge fan of stealth bomber shapes.

    Just saw that headlight a Tractor Supply.

    Bitch, bitch, bitch…

      Talking about insurance and taxes – my son came home from the BMW Motorrad dealership (where he is employed) with another expensive, high-tech bike again this evening and insisted on me taking it for a spin around the block. Glamorous and all but I’m happier with my zero insurance, zero tax, sneak up the road to grab a pizza or trailer it to an off-road wilderness area, every now and again – $1000 bike.

    • When you say ‘interface’, what do you mean? Comfort? Controls? Instrumentation?

      • Greybeard1

        3rd sentence, referencing the seat.
        Looks as comfortable as sitting on a pile of Lego’s.

  • I like the origami sheet metal and the raw look of the aluminum. Reminds me of the furniture of Radek Micka which is cool stuff. Very modern industrial.

  • guvnor67

    Angular and brutish. I’d like to see shorter mufflers with a bit more kick-up, but apart from that, I think it’d be like riding an Italian Stallion that’s snorted something naughty! Kick it in the guts and hold on!!!!

  • the watcher

    Most interesting thing I’ve seen in ages. Love it. The headlight is my least favourite part, but that’s like talking about my least favourite boobs!

  • pgroot

    Reminds me of my friend’s “Woert Hog” Interesting style and name convergence

    wish they would do something more with the headlight, the stock cree fog light looks a little slapped on there.
