Who are we?

Founded in 1967, the French company SECDEM (Société Etude de Construction D'Engin Mécanique) set out to improve rider protection and motorcycle aerodynamics by developing windscreens specifically designed for each model.

It was the first company in Europe dedicated to aerodynamic protection for motorcyclists.

Deeply involved in motorsport (the company also manufactured fibreglass fairings in addition to windscreens), SECDEM deployed its expertise and developed its aerodynamic know-how alongside the greatest GP and Endurance champions of the 1970s.

Every team used SECDEM fairings and/or windscreens at one point or another.

The early 1980s saw competitors multiply, and SECDEM was no longer the sole specialist in aerodynamic protection. A strategic decision was made to focus exclusively on windscreens, wind deflectors, and fly screens, while putting the fairing department on hold.

An intense period of innovation followed: SECDEM developed and patented the universal fly screen "Speedy" in 1985. In 1997, SECDEM became the first manufacturer in the world to offer a double-curvature windscreen (developed for Suzuki Japan) — an innovation subsequently adopted by all competitors and which remains to this day the archetype of the racing windscreen.

Sold by its founding owner in 2005, SECDEM's windscreens were rebranded Bullster, in parallel with the name of its new owner — the company Bagster.

In 2007, the Groupe Holding Trophy acquired Bagster and Bullster, and soon separated from Bullster: the sole technical activity within a group focused on clothing and luggage.

It was therefore in 2010 that SECDEM regained its independence and its historic name.

Since then, SECDEM has established itself as the leading specialist in windscreens for classic motorcycles, while keeping pace with developments for today's modern machines.

SECDEM never forgets that today's modern bikes will be tomorrow's classics!
