Simon grew up in his mother Chris Murner’s leather workshop, where he was immersed in the techniques of the leather professions.
Since 2015, he has been the mechanic for top World Championship drivers such as John McPhee, Alexis Masbou, Albert Arenas, Patrik Pulkkinen, Kaito Toba, Mike Di Meglio and Marco Bezzecchi, a young Italian prodigy spotted and supported by the great Valentino Rossi. Simon finished 3rd in the 2018 World Championship alongside Marco Bezzecchi and won the EWC Endurance World Championship in 2022 with the Honda HRC team.
Curious and inventive by nature, he also began working in motorcycle saddlery, to complement his profession with this new specialization and meet the numerous demands.
Since his arrival in Grand-Prix, he has combined his two passions, and today develops saddles for the world’s greatest riders in the Moto 3, Moto 2, MotoGP, Mondial EWC Endurance, FMX and other categories.
He develops the “flag” saddle with the country of each rider he works for.
Our former national driver Tom Lüthi and the living legend of motorcycle racing Valentino Rossi called on him.
His saddle has also won the Superstock Endurance World Championship in 2019 with our Swiss rider Robin Mulhauser.
He makes all kinds of saddles, caferacer, touring bike, motocross, collector’s bike and even freestyle bikes like the one used by our Swiss rider Mat Rebeaud.
Today, he works on saddles for some of the biggest names in motorcycling, always in the art of made-to-measure. He was recently named 3rd best artist in Switzerland in the “Relève Métiers d’Art” category.
He was also able to share his experience with young apprentice mechanics at the CFPT in Geneva, alongside his racing activities.
Today, he works as a mechanic for FCC, the official Honda HRC team in the EWC Endurance World Championship, and makes his own upholstery creations in his workshop in Plan-les-Ouates.
