DIY: These Yamaha MT 09 parts you can replace yourself

The Yamaha MT 09 is popular among DIY enthusiasts. The bike is built in a clear and accessible way, making many maintenance tasks easy to perform. With a bit of technical knowledge and the right tools, you can save a lot of work (and costs).

Chain and sprockets

A good example is replacing the chain and sprockets. First, check for play on the chain and whether the sprocket teeth are still straight. When installing a new set, it's important to carefully adjust the chain tension. Too tight causes excessive wear; too loose leads to rattling. Always use a torque wrench and recheck the tension after 100 kilometers.

Fork seals and suspension

On older or heavily used MT-09s, oil may leak along the fork seals. You’ll recognize this by greasy spots on the fork legs. New seals or a rebuild kit usually solve this problem. The rear shock absorber can also lose its damping power over time, especially for heavier riders or with passenger use.

Common issue: Oil leakage at the exhaust pipe

Oil leakage at the exhaust pipe sometimes occurs on the Yamaha MT-09, especially on bikes with high mileage or those that have been stationary for a long time. Often, it looks more serious than it is: a few drops of oil burning on a hot exhaust can produce significant smoke and odor. The cause is usually a leaking valve cover gasket or an improperly sealed oil filter.

What are the symptoms?

Do you see oil traces on the top of the engine block running down toward the exhaust? → Then the valve cover gasket likely needs replacing. This part can be replaced by yourself.

Is the leak coming from the oil filter? → Then loosen it and install a new one. Lightly oil the rubber ring before hand-tightening the filter. Wipe away all oil and briefly start the engine. If it remains dry, the problem is solved.

Tip: Also make sure there are no old oil residues or dirt left on the exhaust, as these will burn during the next ride and can cause new smoke.

Electrical issues on the Yamaha MT 09

Older Yamaha MT-09s sometimes experience minor electrical issues. Think of a stuttering quickshifter, an ABS sensor that shows errors after a rain ride, or a dead battery after long storage. The throttle position sensor (TPS) on early model years may also respond erratically, resulting in jerky throttle response. These issues are often easy to fix by cleaning the connectors, checking contact points, or replacing a sensor.

Frequently Asked Questions about Yamaha MT 09 parts

Can I change the oil on the Yamaha MT 09 myself, and how often should I do it?

Yes, changing the oil and oil filter is easy to do yourself. Warm up the engine slightly to thin the oil, drain it, replace the filter, and refill to the correct level as per the manual. Don’t forget to check for leaks after the first ride. Yamaha recommends doing this every 10,000 kilometers or once a year.

Which exhausts and ECU upgrades are popular for the Yamaha MT 09?

Popular choices include Akrapovič, SC-Project, and Arrow exhaust systems. They not only improve the sound but also reduce weight and enhance throttle response. Many riders combine this with an ECU remap or Power Commander for smoother throttle control and more power. Make sure the system fits your model year and complies with local regulations.

Why is the Yamaha MT 09 so popular among riders?

Yamaha motorcycles are known for their reliability, but the MT-09 also delivers high performance for its weight. The CP3 three-cylinder engine provides smooth low-end torque and sporty top-end power, while the riding position remains comfortable. Additionally, the bike is maintenance-friendly and offered at a competitive price.

Which parts on the Yamaha MT 09 wear out the fastest?

On the Yamaha MT 09, the rear tire, brake pads, and chain set wear out the fastest, especially with sporty riding. Also regularly check the fork seals and fender rubbers, as these can leak or dry out due to dirt and weather conditions.
