Rusty Motors builds a Gilera 600 for a Paris Dakar veteran…
In 1991, a French privateer named Hugues Arancio raced a Gilera 600 prototype in the Paris Dakar Rally. His race mechanic was none other than Michel Augizeau, current boss of the BMW Tecmas Racing Team.
Fast forward 30 years, and Arancio wanted to transform his veteran Paris Dakar mount into a street-legal custom that he could continue to enjoy:
“[He] wanted to keep it and absolutely not sell it, but wanted to travel again with a brand new motorcycle in a modern, race-inspired style.”
Arancio and his ’91 Paris Dakar mechanic, Michel Augizeau, got together to envision the build:
“They started to work on the concept from sketches and used parts from the BMW S1000R endurance racer of Kenny Foray (French superbike winner, EWC).”
However, the project remained on the bench for several years until it found its way to Stéphane Bertet of Rusty Motors, a former professional French motocross rider who opened his own shop in 2009 in Provence, France.
“I do classic motorcycle repair, restoration, and customs, and also tune bikes for motocross (engine and suspension).”
Stéphane spent more than 400 hours carrying the project to completion, modifying nearly every last component of the machine, and earning the ultimate congratulations of both Arancio and Augizeau:
“Only the engine and the clutch cable remain original. Each piece was custom built or reworked without exception…for a final result that leaves no one indifferent. But above all a wonderful human adventure!”
The result is a the “Gilera Replay” — a 267-lb one-of-one custom with an incredible racing pedigree, transformed for the man who once raced it from Paris to Dakar.
“Gilera Replay”: In the Builder’s Words…
A year ago, I finished an exceptional motorcycle…finally here are the pictures! It was a real technical and psychological test to carry out this project, which required a lot of hard work!
It started with a Gilera 600 prototype, which had participated in the ’91 Paris/Dakar — stripped and modeled in the workshops of the famous #TecmasRacingTeam.
I then recovered the motorcycle to “build” it: 400 hours of work for me. Only the engine and the clutch cable remain original. Each piece was custom built or reworked without exception…for a final result that leaves no one indifferent. But above all a wonderful human adventure!
• Please tell us a bit about yourself, your history with motorcycles, and your workshop.
Hello, I’m Stéphane, 41. I got into motorcycles through my dad and started riding motocross when I was 5 years old. At 12, I started to work on my own machine and built some projects based on a Solex, Peugeot 103, Honda CR, and so on. At 15 I became a mechanic and then tried several different jobs (plumber, postman, cabinet maker). Until I was 22, In continued racing motocross in the French championship, and then I gave up everything and went to enjoy the life in Australia for nearly two years.
I came back and started my workshop, first doing polishing and sand blasting on old airplane parts, making them into furniture. Then I created Rusty Motors in January 2009 in the south of France, in the wonderful Provence, near Avignon.
I work on classic motorcycle repair, restoration, and customs, and also tune bikes for motocross (engine and suspension).
• What was the design concept and what influenced the build?
The Gilera Replay was a bike raced in the Paris Dakar Rally. The customer wanted to keep it and absolutely not sell it, but wanted to travel again with a brand new motorcycle in a modern, race-inspired style.
His 1991 Dakar mechanic was Michel Augizeau, the boss of the BMW Tecmas Racing Team. They started to work on the concept from sketches and used parts from the BMW S1000R endurance racer of Kenny Foray (French superbike winner, EWC). But the project remained on the bench for a couple of years…then I got it in my workshop, along with all the desired specifications.
It was a really hard job to build the entire bike, especially when you know you are working with the best, and we were 800kms away, so we spent heaps of time on telephone; but in the end, it was an awesome project and human adventure, which made everyone happy.
• Can you tell us what it’s like to ride?
The bike is not very powerful, but it’s really fun to ride, very light, and precise in the curves — and the look is just unique!
• Was there anything done during this build that you are particularly proud of?
I spent 400 hours building or modifying every single part — only the clutch cable remained untouched — so I can say I’m proud not only to accomplish the entire bike, but to have the congratulations from the customer and from Michel Augizeau.
