“Crazy Bonnie” Street Dragster by FCR Original

Triumph Bonneville Street Dragster

A lot of the customs we see look great, but are rarely put to the test on the road or track. Not so with “Crazy Bonnie” — a 2006 Triumph Bonneville street dragster that recently took first place in the drags at Monza.

The bike is the creation of French workshop, FCR Original, founded five years ago by engineers Mathieu Ménard (29 years old) and Sébastien Guillemot (33 years old), who work with Espera Sbarro, an expert in composite materials and bodywork. This crew has quickly displayed their bike-building prowess, winning several French Dragster National Championships, with wins in 2012 and 2013 in the Street Bike category, then 2014 French vice-champion in the Super Street Bike category.
