Ce que les acheteurs doivent savoir
KTM Engine Roots
The Rieju Marathon 500 uses a Rotax-derived engine with strong KTM lineage, giving it a well-proven powerplant with established parts availability. This shared DNA means mechanics familiar with KTM adventure bikes can service it with confidence.
Watch Electrical Gremlins
Early Marathon 500 models are known to have intermittent electrical issues, particularly with the fuel injection system and wiring connectors in off-road conditions. Inspecting the harness and connectors before purchase is strongly recommended.
Lower Resale Value
As a lesser-known Spanish brand, the Marathon 500 depreciates faster than comparable KTM or Husqvarna adventure bikes, making used examples excellent value for buyers. However, this also means reselling later may require patience to find the right buyer.
Évaluation d'un acheteur d'occasion
"A genuine off-road weapon if you can handle the ownership quirks."
$5,500-$8,500 usedThe Rieju Marathon 500 is one of those bikes that rewards patient, mechanically sympathetic riders and punishes everyone else. Built around a KTM-derived 450cc single (yes, the badge says 500 but the engine tells a different story), it's essentially a Spanish-assembled adventure enduro wearing dual-sport clothes. On dirt it's genuinely brilliant — lightweight, flickable, with proper suspension travel that shames heavier adventure bikes costing twice as much. Road manners are acceptable rather than inspiring, and that thumper vibration gets tiresome on long tarmac slogs. Used examples need careful inspection. Spanish build quality has improved but early units had electrical gremlins, particularly dodgy connectors and temperamental dash units. Check the subframe for cracks — these bikes get ridden hard. Parts availability is improving but still nowhere near KTM levels, so budget accordingly and find a dealer before you buy, not after something breaks 200 miles from home. Service intervals are tight for an adventure bike, so demand a proper history.
