The Honda Crf450rx has a top speed of ~170 km/h (estimated; note: top speed is not the primary design focus of this off-road machine), produces ~56 hp and weighs 110 kg. Motoryk rates it 8.5/10.
De Honda CRF450RX werd in 2017 geïntroduceerd als een off-road/enduro-variant met gesloten baan van de CRF450R crossmotor, ontworpen om de kloof te overbruggen tussen pure MX-races en offroad-/crosscountry-wedstrijden. Het beschikt over belangrijke verbeteringen ten opzichte van de MX-broer van de RX, waaronder een 18-inch achterwiel, een grotere brandstoftank, een elektrische start en een zachtere afstelling van de vering die geschikt is voor races in enduro- en GNCC-stijl. Het werd al snel populair onder competitieve offroad-racers die op zoek waren naar een machine op fabrieksniveau voor disciplines zoals EnduroCross, GNCC en WORCS.

Wat kopers moeten weten
Strict Valve Service Intervals
The CRF450RX requires valve clearance checks every 24 hours of riding — skipping this is the #1 cause of expensive engine damage. Always ask a seller for documented valve service history before buying.
Strong Resale Value
Honda CRF450RX models hold their value exceptionally well, often retaining 70-80% of MSRP after one year. Low-hour, well-maintained examples are in high demand and sell quickly on the used market.
Trail-Ready from Factory
Unlike the race-focused CRF450R, the RX comes stock with an 18-inch rear wheel, larger fuel tank (2.1 gal), and a quieter exhaust — making it genuinely competition-legal and trail-practical without costly modifications.

Beoordeling van gebruikte kopers
"Exceptional used buy if maintenance history checks out completely."
$7,500-$10,500 usedThe CRF450RX is genuinely one of the best off-road bikes Honda has built in years, but buying used requires some homework. These things get flogged hard by enthusiasts who actually know how to ride, so maintenance history matters enormously. The 450cc engine produces serious power that needs regular valve checks — skip that and you're looking at a top-end rebuild before you've even enjoyed a weekend ride. Always verify the air filter condition and ask about oil change intervals honestly. When maintained properly, the RX rewards you with class-leading suspension tuning straight from Honda's HRC-influenced setup, and that electric starter is genuinely life-changing on technical terrain. The 18-inch rear wheel makes it far more capable on longer trail rides than a pure motocrosser. Hours meter reading is your best friend here — anything over 80 hours without documented valve service, walk away or negotiate hard for the rebuild cost.
