Honda CRF450RX CRF450X CRF450RL 2022. About updated models

After major changes for '21, Honda has made almost no changes to the 2022 model, but there are still some. Honda tried to solve the problem noted by many with the sluggish response of the current year model by updating the firmware of the control unit. They also changed the suspension settings. These two changes affected the top-end RX model (it’s top-end because it’s on a new platform), while the X, RL (previously just L) models remain on the 2021 platform (without hydraulic clutch and other things).

The Honda CRF450RX is designed for off-road racing on a closed track, while the CRF450X, on the other hand, is designed for open spaces - including desert rally racing. The CRF450RL allows you to combine riding in the most remote places and moving on asphalt.

Proper running-in of an all-terrain vehicle is the key to its long and trouble-free operation in the future, so special attention should be paid to the correct operation of the all-terrain vehicle during the first day or 25 kilometers.

During the break-in period, avoid running the engine at full throttle, sudden acceleration and driving at a constant speed.

Use of alcohol-containing fuels

If you choose to run your engine on gasoline containing alcohol, make sure the fuel's octane rating is at least equal to that recommended by Honda.

There are two types of alcohol-containing gasoline. One of them contains ethanol, and the other contains methanol. Do not use gasoline containing more than 10% ethanol. Do not use gasoline containing methanol (wood alcohol) unless it contains solvents and inhibitors that reduce the corrosiveness of methanol. Do not use gasoline containing more than 5% methanol, even if it contains solvents and corrosion inhibitors. Damage to parts of the fuel supply system, as well as deterioration in engine performance that occurred due to the use of gasoline containing alcohol, is not covered by the factory warranty.

Honda cannot support the use of gasoline containing methanol as there is currently no comprehensive evidence of its suitability. Before filling up at an unfamiliar gas station, try to find out if the fuel contains alcohol.

If it is, find out the type of alcohol and its percentage in the fuel. If you notice signs of engine malfunction when using gasoline that contains, or may in your opinion, contain alcohol, then stop operating the engine using that fuel and use only gasoline that is guaranteed to be alcohol-free.

The lineup

The line of ATVs offered by Honda is divided into three types depending on their purpose:

Working in high altitude conditions

• Text

When the engine operates at high altitudes above sea level, the air-fuel mixture becomes over-rich. At an altitude of more than 1500 meters above sea level, over-enrichment of the air-fuel mixture can lead to a significant deterioration in engine performance and increased fuel consumption. Therefore, it is necessary to adapt the engine to work in high altitude conditions. In this case, contact your authorized Honda dealer.

To operate in high altitude conditions, it is necessary to install appropriate jets. If you have the necessary tools and technical skills, you can purchase a Workshop Manual from your authorized Honda dealer, which provides installation and adjustment procedures. Otherwise, have your carburetor adjusted by an authorized Honda dealer.

Before operation at altitudes below 1500 meters above sea level, it is necessary to reconfigure the carburetor.

Driving at high altitude settings may cause rough idle and engine overheating.

Instructions: “It is prohibited to disassemble the device. There are no parts that can be repaired by the user.” The manufacturer intrigued me. Almost provokes!
