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 an 8-litre fuel tank, offers a seat height of 964 mm and spans a 1477 mm wheelbase. That's roughly 61.6 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 Honda CRF250RX compared with other bikes in the Enduro / Off-Road category

Measured against other bikes in the Enduro / Off-Road category in our database (up to 1146 models, one entry per model), the 2023 Honda CRF250RX comes out as follows.

With 964 mm, the CRF250RX has the 69th tallest seat height of 1146 bikes in the Enduro / Off-Road category, 10% above the category average of 879 mm.
Wet weight of 108 kg is lighter than that of 686 of the other 773 bikes in the Enduro / Off-Road category.
Narrowing the field to the 408 models within five model years of it, the seat height of 964 mm is taller than that of 398 of the other 407.

Versus the 2022 model

The figures we track are unchanged from the 2022 model: wet weight, displacement and seat height all match.

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.
Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.

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: An 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 with 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 with its 249.4 cc enduro / off-road should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 3 years old, this enduro / off-road is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. 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 the CRF250RX's 249.4 cc single cylinder, four-stroke - 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. With a 13.9:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. 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.
