Red Hot: A bobbed Bonneville Bobber hot rod from Paris

The fastest-selling Triumph motorcycle in history has been in showrooms for around a year now. But we haven’t seen many custom jobs, because the Bonneville Bobber does everything very well—except carry passengers, for which we have the new Speedmaster.

But if you’ve got a Bobber and have an itch to modify it, let Modification Motorcycles of Paris be your guide. Raphael, Florian and Morgan have spent five months subtly tweaking a Triumph Bobber to give it an extra performance edge—and a not-so-subtle dash of style.

Working with their client, Modification Motorcycles decided to take a ‘factory custom’ approach: what would Triumph themselves do if they were to build a one-off suitable for daily use? It turned out to be a rather more complex process than les gars originally anticipated.

The first job was to remove the tall and narrow front wheel. “We replaced the entire front end with a Thruxton R setup: the forks, 17-inch wheel, fender and clip-ons.”

It was not a plug-and-play operation to make the high-performance front end fit the Bobber frame: a new set of triple tees was CNC machined up, with inserts to accommodate a Motogadget Motoscope mini speedo and idiot lights. It’s a functional yet minimalist dashboard.

The original headlight bowl remains, but it’s now filled with an LED lamp. The handlebars were a little harder to finish: they needed to keep the ride-by-wire cabling and module essential for the traction control, drive modes and on-board computer functions.

The electrics have been upgraded with a full Motogadget set, from mini-buttons to mirrors and bar-end turn signals. “The braking had to be French though,” says Raphael.

“So we worked with Beringer to create a gorgeous race-level braking kit. It’s a masterpiece of efficiency and ‘feel,’ with devilish performance!”

Next up on the list was a rewire. The panels under the seat are gone, giving the Bobber a much lighter look when viewed from the side.

“We removed the airbox and the side panels, and all the crazy wiring that was hidden behind them,” says Raphael. “And that was the trickiest part of the project: the entire loom has been reduced to the max, and is now hidden inside the original battery box, which sits on the lower left side of the bike.”

The effort was worth it: the beautiful rear linkage arrangement is now on view, complete with a custom shock specifically developed for the build by Shock Factory. A slightly bobbed rear fender accentuates the look.

Close inspection reveals a belt drive conversion, which we’ve never seen before on the Bobber. “It’s an excellent kit produced by FreeSpirits that gives the bike a custom touch, and a very soft launch from standstill, even in low revs,” says Raphael.

The Vance & Hines pipes are straight from the Triumph accessory parts list. They sound terrific, fit easily, and comply with noise regulations—perfect for the regular use this Bobber will see.

The paint is most definitely not from a catalog, though. Much of the existing metalwork on the Bobber has been blacked out, echoing Triumph’s own Bobber Black, and the paint gets its depth from three layers of black flake under the top coats. Depending on the light and angle, the shade changes from a deep cherry red to a dark orange.

The seat is sure to polarize opinion. “Ah, the seat! It’s covered with red crocodile leather,” says Raphael. “Like it or not, the floating seat is the signature of the original Bobber, and the croc leather is the signature of our build.”

“Without it, the bike would be so plain and neat: it adds the extra madness that we needed.” It’s also added a bit of extra technology, because there’s a tiny LED strip running across the back of the seat.

Modification Motorcycles’ Bobber is close to being a perfect ‘real-world’ custom: an already good platform given a boost in style and handling, without compromising usability.

“That was the purpose,” Raphael agrees. “The bike is very usable day-to-day, with a supple engine, comfortable seating, good handling and incredible braking.”

“There are even decent fenders if you cannot dodge the puddles!”
