Custom Rumble: Untitled x Marin Ducati Scrambler

Last year, Ducati launched the ‘Custom Rumble’ contest. It’s a worldwide dealer build-off, based on the Ducati Scrambler, where the winner is chosen by public vote.

But how do you customize a bike that already has a trending look? The finalists have been chosen, and many entrants have visibly wrestled with that challenge. Not Marin Speed Shop though—they hooked up with Untitled Motorcycles of San Francisco, and threw the Scrambler styling rulebook out the window.

“The new Ducati Scrambler is a great platform,” says Untitled’s Hugo Eccles. “It does an admirable job of capturing the essence of the original Scrambler, but with certain inevitable cost and production compromises”.

When Marin Speed Shop’s Jim MacLaughlin suggested they partner up, Hugo jumped at the opportunity to fix those compromises.

“I love Ducati’s signature trellis frame on the Scrambler, and wanted to celebrate it,” he says. So he started by replacing the stock swingarm with a Ducati Monster S2R unit. Its tubular structure’s a much better match for the bike’s frame.

A new subframe was needed to accommodate the S2R mono-shock—so the guys turned to a local fabricator, Turk’s Shop, to build one. The new front forks are Showa units from a Suzuki GSX-R, and the new 17-inch wheels are from a Monster M796 (front) and Monster 1100 (rear).

Up top is a brand new steel fuel tank, hand-made by Untitled and designed to house the original fuel pump. Hugo went for a slim, tapered feel—creating a unified form from the aluminum headlight housing, through to the tank and minimal seat.

“The new design also suggests a more pared-down flat track and supermoto-inspired style,” he says, “which I feel is compatible with the Scrambler’s DNA.”

The next phase of the project saw the team strip all extraneous details and components, including two large tubs full of plastic bits. This resulted in a 85lbs weight saving; this Scrambler now weights in at 325lbs.

Visually, Untitled split the Scrambler into three elements: the engine, frame and body. A ‘Rosso Corsa’ paint job helps the frame stand strong, with desaturated tones above and below.

Even the engine’s had some serious treatment—stripped and vapor blasted for a raw, mechanical vibe. The point is driven home with details like the re-worked stator cover and exposed belts. Drawing a line at the bottom is a custom-made belly pan, and a modified QD Exhaust Ex-Box system.

The rest of the bike’s finishes are equally thoughtful. Twin LEDs in the rear loop act as both turn signals and a rear light, with LEDs embedded in the hand controls doing duty up front. And a tiny Motogadget LED speedo flows flawlessly off the top of the triple clamp. In fact, there’s hardly a joint, bracket or fastener in sight.

Hugo makes no bones about the fact that this build is a bit of a departure from Untitled’s usual style.

“It’s a competition build, so we set out to do something intentionally provocative,” he explains. “Although this bike is road legal, the next road-going versions will be designed and detailed differently.”
