2023 Honda CRF250RX Overview
For 2023, Honda offers the CRF250RX as an enduro / off-road motorcycle with 249.4 cc on tap. The 2023 Honda CRF250RX is built around a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 13.9:1. Internally, bore and stroke are 79 x 50.9 mm. In everyday use, the 2023 CRF250RX tips the scales at 108 kg, carries a 8-litre fuel tank, offers a seat height of 964 mm and spans a 1477 mm wheelbase. That's roughly 90.8 kg lighter than the average enduro / off-road motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2023 Honda CRF250RX spec sheet below.
2023 CRF250RX - Pros & Cons
Strengths
-
🔧
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
Considerations
-
📏
Tall seat height: A 964 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
-
⛽
Modest fuel capacity: A 8-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Fuelling & injector care
Fuelling on the CRF250RX comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.
Valve clearance checks
Valve clearances on Double Overhead Cams/Twin Cam (DOHC)-equipped engines like the CRF250RX's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.
Brake disc and pad wear
Single disc. Hydraulic up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by 49mm leading-axle inverted Showa® SPG coil-spring fork with rebound- and compression-damping adjustability up front and Showa single shock with spring preload, rebound- and compression-damping adjustability at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the CRF250RX means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Aluminium twin tube chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
Low-speed handling
The CRF250RX's 108 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.
CRF250RX - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2023 Honda CRF250RX should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept CRF250RX settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for a CRF250RX's engine - keep to the manufacturer's interval rather than stretching it. The sump holds 1.40 litres, so budget for that volume of quality motorcycle-specific engine oil. Use the viscosity grade the manual specifies, not whatever's on sale.
Fuel system care
Injector systems like the CRF250RX's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
Valve clearance service
There's no reliable seat-of-the-pants way to tell if a CRF250RX's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
