2006 Honda CRF 250X Overview
The 2006 Honda CRF 250X is an enduro / off-road motorcycle built around 249 cc of displacement. Under the tank sits a Single cylinder engine, a compression ratio of 12.5:1. The bore and stroke measures 78 x 52.2 mm. From a practical standpoint, the 2006 CRF 250X tips the scales at 102.1 kg, carries a 8.32-litre fuel tank, offers a seat height of 958 mm and spans a 1,481 mm wheelbase. That's roughly 96.7 kg lighter than the average enduro / off-road motorcycle in our database.

2006 CRF 250X - Pros & Cons
Strengths
-
✓
Factory engineering: The 2006 Honda CRF 250X represents Honda's engineering at the time, with a specification built around real-world usability.
Considerations
-
🔧
Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.
-
📏
Tall seat height: The 958 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
-
⛽
Modest fuel capacity: The 8.32-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
-
⚙️
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.
Wear Points & Servicing Notes
Carburetor maintenance
The CRF 250X uses carburetion rather than fuel injection, which means jetting is altitude- and temperature-sensitive and benefits from a clean-and-rejet after extended storage or an exhaust change.
Brake disc and pad wear
The Single disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the CRF 250X runs 47.0mm inverted Showa cartridge fork with 16-position rebound and 16-position compression damping adjustability and Pro-Link Showa single shock with spring-preload, 17-position rebound-damping adjustability, and compression-damping adjustment separated into low-speed at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.
Low-speed handling
At just 102.1 kg, the CRF 250X is light enough to manhandle easily at a standstill - one of the practical advantages of its class.
CRF 250X - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2006 Honda CRF 250X, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained CRF 250X should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any CRF 250X. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Carburetor upkeep
Keep the carburetors clean and free of deposits. If the CRF 250X has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
