Sherco Se 450i
The Sherco Se 450i has a top speed of ~155 km/h (estimated; note: primarily an off-road enduro bike), produces ~55 hp and weighs ~113 kg. Motoryk rates it 7.5/10.
Le Sherco SE 450i fait partie de la gamme enduro du constructeur français Sherco, la variante « i » à injection de carburant ayant été introduite vers 2018 alors que la marque modernisait sa gamme d'enduro à quatre temps avec injection électronique de carburant. Sherco, fondée en 1998 et basée à Nîmes, en France, a bâti sa réputation principalement lors des essais avant de s'étendre de manière agressive à la compétition d'enduro, avec la SE 450i destinée aux pilotes d'enduro exigeants et d'enduro extrêmes à la recherche d'une machine à cylindrée élevée. Le modèle a été compétitif lors d'événements tels que le Roof of Africa et d'autres championnats d'enduro difficiles, ce qui a contribué à améliorer le profil de Sherco face à des concurrents de renom tels que KTM et Husqvarna.

Ce que les acheteurs doivent savoir
Fuel Injection Advantage
The 'i' in SE 450i stands for fuel injection, giving it superior cold-start reliability and consistent throttle response compared to carbureted competitors. This also means fewer jetting adjustments when riding at different altitudes.
Watch the Valves
The 450cc engine is known to require more frequent valve checks than some rivals, so budget for inspections every 30-40 hours of hard enduro riding. Neglecting this is the most common cause of costly engine damage reported by owners.
Strong Resale Hold
Sherco's growing reputation in hard enduro — bolstered by strong results at events like Erzbergrodeo — keeps used SE 450i values relatively solid. Low production numbers also limit market saturation, helping prices hold better than mainstream brands.

Évaluation d'un acheteur d'occasion
"Outstanding enduro machine undermined badly by real-world ownership practicalities."
$4,500-$7,500 usedThe Sherco SE 450i is a proper weapon if you know what you're getting into. French-built with Marzocchi forks and a punchy fuel-injected 450 single, it punches well above its obscure badge in the enduro world. Used examples from serious riders will have taken a beating, so budget for a suspension refresh and check the airbox area obsessively — these things swallow dirt if the previous owner got lazy with maintenance. The fuel injection genuinely transforms the riding experience compared to carb-fed competitors. Cold starts are drama-free, and the throttle response in tight technical sections is predictably smooth. Parts availability is the elephant in the room though — Sherco's dealer network in North America and the UK is thin. You'll be waiting on European shipments for anything beyond consumables, which gets expensive and frustrating fast. Buy one from a fastidious owner with receipts and you've got a legitimate KTM-beater at a significant discount. Buy one blind off a muddy truck and you're gambling with something that can be genuinely difficult to fix affordably.
