The CFMOTO 450 MT requires unleaded petrol with a minimum octane rating of 92 RON (Research Octane Number). This adventure motorcycle’s parallel-twin engine is designed to run efficiently on regular unleaded fuel available at most petrol stations. Using the correct fuel type ensures optimal performance, prevents engine knock, and helps maintain warranty coverage for your CFMOTO 450 MT adventure bike.
What type of fuel does the CFMOTO 450 MT require?
The CFMOTO 450 MT requires unleaded petrol with a minimum octane rating of 92 RON. This fuel specification applies to both the standard CFMOTO 450 MT and the CFMOTO Ibex 450 variants. The manufacturer specifically recommends avoiding leaded fuels, ethanol blends above 10%, and any fuel additives not approved for motorcycle use.
The fuel tank capacity of 12.5 litres means you’ll want to ensure consistent fuel quality across different filling stations. Most standard unleaded petrol meets the 92 RON requirement, but premium fuels (95–98 RON) can also be used without any modifications to the engine management system.
When travelling on adventure routes, particularly in remote areas, carry a fuel stabiliser if you need to store petrol for extended periods. The CFMOTO 450 MT’s fuel injection system is calibrated for clean, fresh fuel, and contaminated or stale petrol can cause starting difficulties and reduced performance.
Why does octane rating matter for the CFMOTO 450 MT?
Octane rating determines the fuel’s resistance to premature ignition, or “knocking,” in your CFMOTO 450 MT engine. The parallel-twin engine has a compression ratio that requires 92 RON fuel to prevent knock, which occurs when fuel ignites before the spark plug fires. This premature combustion creates a metallic knocking sound and reduces power output.
The CFMOTO 450 MT adventure motorcycle’s engine management system is programmed to work optimally with 92 RON fuel. Using lower-octane fuel forces the ECU to retard ignition timing, resulting in decreased power, reduced fuel economy, and increased exhaust temperatures. Over time, persistent knocking can damage pistons, cylinder heads, and other internal components.
Higher-octane fuels (95–98 RON) won’t harm your CFMOTO 450 MT dual-sport bike, but they typically don’t provide performance benefits unless the engine is specifically tuned for them. The additional cost of premium fuel usually isn’t justified for standard riding conditions, though some riders report smoother running in extreme heat or at high altitudes.
What happens if you use the wrong fuel in a CFMOTO 450 MT?
Using incorrect fuel in your CFMOTO 450 MT can cause immediate performance issues and long-term engine damage. Low-octane fuel below 92 RON can cause engine knock, reduced power output, poor throttle response, and increased fuel consumption. The engine may also run rough at idle and produce higher exhaust emissions.
Contaminated fuel or water in the fuel system can clog the fuel injector and damage the fuel pump. The CFMOTO Ibex 450’s sophisticated fuel injection system is particularly sensitive to debris and water contamination. Symptoms include difficulty starting, an irregular idle, and sudden power loss during acceleration.
Using leaded fuel or inappropriate additives can damage the oxygen sensors and catalytic converter, leading to expensive repairs. Most importantly, fuel-related damage may void your warranty coverage, leaving you responsible for repair costs. If you accidentally use the wrong fuel, drain the tank immediately and refill with the correct specification before starting the engine.
Ethanol blends above 10% (E10) can cause fuel system corrosion and rubber seal degradation over time. The CFMOTO 450 MT off-road bike’s fuel lines and seals are designed for standard unleaded fuel, and higher ethanol content may cause premature component failure.
How do you maintain the fuel system on a CFMOTO 450 MT?
Regular fuel system maintenance keeps your CFMOTO 450 MT adventure bike running reliably during long adventure rides. The fuel filter should be replaced every 12,000 kilometres or annually, whichever comes first. A clogged filter restricts fuel flow and can cause lean running conditions that damage the engine.
Clean the fuel tank annually by removing any water or sediment that may have accumulated. Water contamination is particularly common when riding in humid conditions or storing the motorcycle for extended periods. Use a fuel system cleaner every 5,000 kilometres to keep injectors clean and maintain optimal spray patterns.
Key maintenance practices include:
- Replace the fuel filter according to the service schedule
- Use fuel stabiliser when storing for more than 30 days
- Keep the fuel tank full during storage to prevent condensation
- Inspect fuel lines for cracks or deterioration every 6 months
- Clean the fuel injector every 10,000 kilometres, or if performance drops
Monitor fuel consumption patterns, as sudden increases may indicate injector problems or air leaks in the fuel system. The CFMOTO Ibex 450 motorcycle should achieve consistent fuel economy under similar riding conditions, making changes easy to detect.

Frequently Asked Questions
Can I use E85 or other high-ethanol fuels in my CFMOTO 450 MT?
No, you should not use E85 or ethanol blends above 10% (E10) in your CFMOTO 450 MT. The fuel system components, including seals and fuel lines, are designed for standard unleaded petrol and can be damaged by higher ethanol concentrations. Stick to regular unleaded fuel with maximum 10% ethanol content to avoid costly repairs.
How can I tell if I've accidentally used contaminated fuel?
Signs of contaminated fuel include difficulty starting, rough idling, sudden power loss during acceleration, and unusual engine noises. If you suspect fuel contamination, stop riding immediately and drain the fuel tank. Have the fuel system inspected by a qualified mechanic before refilling with clean, fresh fuel to prevent further damage.
Is it safe to mix different octane ratings in the same tank?
Yes, mixing different octane ratings is generally safe and the resulting blend will have an intermediate octane rating. For example, mixing equal parts 91 RON and 95 RON fuel will give you approximately 93 RON. However, ensure the final blend meets the minimum 92 RON requirement for your CFMOTO 450 MT.
What should I do if my CFMOTO 450 MT starts knocking after refueling?
Engine knocking after refueling usually indicates low-octane fuel or contamination. Stop riding immediately and check your fuel receipt to verify octane rating. If you used correct fuel, the issue may be contamination or water. Drain the tank, refill with fresh 92+ RON fuel, and if knocking persists, consult a mechanic as internal engine damage may have occurred.
How long can I store fuel in my CFMOTO 450 MT without additives?
Without fuel stabiliser, petrol begins to degrade after 30 days and can cause starting problems and injector clogging. For storage periods longer than a month, add fuel stabiliser and keep the tank full to prevent condensation. For storage over 3 months, consider draining the fuel system completely and refilling with fresh fuel before use.
Will using premium fuel improve my CFMOTO 450 MT's performance?
Premium fuel (95-98 RON) won’t provide noticeable performance improvements in a stock CFMOTO 450 MT, as the engine is optimized for 92 RON fuel. The extra cost is typically not justified unless you’re riding in extreme conditions like high altitude or extreme heat, where some riders report smoother operation with higher octane fuel.
What's the best way to clean fuel injectors on a CFMOTO 450 MT?
Use a quality fuel system cleaner every 5,000 kilometres by adding it to a full tank of fuel and riding normally until empty. For more thorough cleaning every 10,000 kilometres, consider professional ultrasonic injector cleaning. Avoid over-the-counter injector cleaners with harsh chemicals that may damage seals, and always follow manufacturer recommendations for cleaning products.
