BADA-BING BADA-ZOOM. Wrench Kings’ ‘Mobster’ Ducati Monster Cafe Racer

Giving you new custom bike a Mafia-related name requires a certain amount of bravado. After all, portraying something that’s got your life in its hands as a violent, vindictive and possibly unhinged criminal doesn’t bode so well for your future personal safety. Open the garage door one sunny Sunday to find it in a bad mood and you could well end up riding with the fishes. Luckily for us, the Netherlands‘ Wrench Kings are still healthy enough to tell us about this, their brand new Ducati Monster cafe they’ve named ‘Mobster’.

“A few months ago Robbie stepped into our shop and asked us to build his dream Ducati Monster,” says the Wrench King’s Take. “He had started the build himself, but he wasn’t able to complete it due to a lack of time. So we kicked things off with the bike’s design. We asked Robbie exactly how his dream bike was going to look. After a few meetings with the Kings, Robbie gave us the thumbs up and we started the build”.

No one does that ‘engine on wheels’ look better than Ducati

They started the Ducati build by stripping the bike to the bone. Just like a pro disposing of a dead body, all the parts were removed and the frame was cut to make things a little more manageable. “The rear of the frame was shortened and it got a new custom hoop, which really gave it a cleaner, more compact look”.

“After finishing the rear frame, we started working on the custom seat pan. Because of the original factory ‘dents’ in the tank, we had to come up with a design for the seat pan that would cover this up, or at least work with it. It was a hell of a job but we think it turned out pretty well”.

The new custom-made rear end was fitted to the frame and a whole host of fresh custom parts were added, including some tasty Motogadget bar-ends and a set of Italian G&G cans. “Once the fitment was perfect, we started to disassemble everything and made the frame, tank and any other soon-to-be-painted parts sandblast ready. After blasting they were cleaned, painted and topped off with a shiny new 2-pack clear coat”.

The front fork was sent to local shock shop HK suspension for a complete overhaul and the ECU went to Carmo Electronics in Helmond to be re-mapped. The beautiful leatherwork on the seat and grips was done by Miller Kustom Upholstery while the Kings started refurbishing the wiring loom for a cleaner, neater look.

“The hardest part of the build was definitely the Ducati’s electronics. We removed the original gauges and replaced them with an Acewell unit, but there was a catch. When you change the gauges like this, the bike won’t start due to the mapping of the ECU”.

When the problem came up, Take and the team thought that they had made some mistakes when re-wiring the loom. Fast forward though a whole bunch of time, phone calls, blood, sweat and some tears before they found out that the problem was actually in the ECU. “After we found out and re-mapped it, the guys from Carmo decided to pay us back in kind by giving the bike a few extra horses”. They sound like real keepers.

“The Mobster came out pretty well, we think. By cutting the frame and making the rear more compact, we made an original bike no one has ever seen before. The color scheme of the bike is from the old school Duc’s and gives it an authentic look. The leather work looks great with the blue paint and the new parts are all top-shelf quality, making it a bike we’re happy to put our name on”.

Motogadget indicators show the way

“And what makes this Ducati the best?” Take asks. “Riding it. It’s really been transformed and we’d put money on the fact that it will give most bikers one hell of a big smile on their faces”.

Looks smoky. Damn Dutch coffee shops

    Having built a few SS’s I absolutely love the EFI Aircooled Ducati motors, but the Monster is not an easy bike to make a custom out of, primarily because of the trellis frame having a pretty ugly tail that just stops dead, squared off, that’s easier to cover on an SS. This is a really really good solution, the hoop looks completely integrated into the frame, the light tail piece smooths out the lines and then with no hugger I love the look of seeing all that rear tyre.

    The paints, beautiful, the front end looks super trick with the gold stanchions and how many customs can you ride comfortably looking this good with an engine that’ll do a 100,000km wthout even trying, money very well spent!!!

      Oddly, I was thinking that it doesn’t seem to matter what you try with the a/c Monster, you can’t get rid of the “humpty-backed camel” of a tank. Further proof, if needed……

      • I love that look. It has a real racer/aggressive vibe to me.

        • the watcher

          Imagine it with a 749/99 flat-topped tank. Course, it’d have no air-box and very little fuel, but…..

    There is so much aesthetically wrong with this bike I don’t know where to begin – but I do know that it ends with ugly. Sorry to be so harsh but this is just terrible.

      Euhm agreed. Don’t see how this seat solution complements the original, superb design. Usually a fan of the Kings, this doesn’t flow my boat

      • Why does the seat have to compliment the original bike?

        • JayJay

          I said the original design.
          The seat doesn’t match with the design of the tank . There is no flow anymore ( the original has that) and I’m not a fan. Looks like a Quality build, just don’t like the design .

    • Not really sure what you mean. It’s a pretty mild custom in anyone’s books. What’s not working for you?

      • Soapy Loofah

        I’ll start with saying that all of the following comments are simply about aesthetic choices and not about the general quality of the build (which appears to be really well done), so to my eye:
        – the tank over-powers the bike, it’s bulbous and the cropped seat only exacerbates the issue
        – the seat, is thin, and disproportionately small. It is the current trend, but with the large tank and no tail/fender it just hangs out there and dead-ends the top line of the bike
        – the headlight is popped out/away from the gauges and appears also disconnected from the rest bike. It’s pretty big too, though that might not be an issue if were tucked in…
        – the stance is wrong, the front is too high and the lack front fender creates too much negative space.

        Again, just my opinion and I realize that many (most) people will disagree with all that, but that’s how I see it.

          ‘Cyclops’ is the ‘new thing’…’yeah nah’.

          • Al

            Well, better than a ‘Alloy tampon’.

    Bellisima! What a kool bike, short, stubby aggression, mixed with fresh, bright colours and a “Ride me til it hurts!” kinda vibe. Excellent.
