The Yamaha MT-09 is a popular motorcycle, but some riders are concerned about its fuel tank size. The bike's standard 14-litre fuel tank may be a drawback for those looking for longer distances between refuelling stops. The larger fuel tank of the MT-09 Tracer, at 17 litres or 18 litres, depending on the source, could be a desirable upgrade for MT-09 owners. While some forum users have considered swapping the tanks, it is unclear if anyone has successfully done so, and it may not be a simple process. One forum user has started an FJ swap but has put the project on hold. There are also concerns about the complexity of the tank shape, which may impact fuel level readings.

The MT-09 Tracer's fuel tank is 17L, 3L more than the MT-09
The Yamaha MT-09 Tracer has a fuel tank capacity of 17 litres, which is 3 litres more than the MT-09's 14-litre tank. This extra capacity translates to a significant increase in riding range, allowing riders to travel further without worrying about refuelling.
The larger fuel tank on the MT-09 Tracer provides a practical advantage for those seeking longer distances between fill-ups. With 3 extra litres, riders can expect to cover approximately 160 miles before needing to refuel, compared to the MT-09's range of around 85-90 miles. This extended range not only reduces the frequency of fuel stops but also offers peace of mind, addressing the "range anxiety" associated with smaller fuel tanks.
The additional fuel capacity of the MT-09 Tracer is particularly beneficial for those embarking on longer journeys or touring. The ability to ride for extended periods without worrying about fuel levels enhances the overall riding experience, eliminating the need to constantly search for fuel stations. This increased capacity can be a deciding factor when choosing between the MT-09 and the MT-09 Tracer, especially for those who prioritise range and fuel efficiency.
Furthermore, the larger fuel tank of the MT-09 Tracer contributes to improved fuel economy. While the MT-09 Tracer may have a larger tank, the extra fuel capacity does not compromise the bike's overall performance or efficiency. In fact, the Tracer's ability to achieve impressive mileage on a single tank of fuel underscores its efficiency and makes it a more economical choice for riders seeking to maximise their riding range.
The MT-09 Tracer's 17-litre fuel tank offers a notable upgrade over the MT-09's 14-litre tank, providing increased range, reduced refuelling stops, and improved fuel economy. This larger fuel capacity is a significant consideration for riders seeking a more versatile and efficient motorcycle, particularly for those embarking on longer journeys where maximising distance between fill-ups is a priority.

The larger tank means less concern about how far you can go
The MT-09 Tracer's 17-litre fuel tank can potentially be fitted onto the MT-09, which has a 14-litre tank. This would provide riders with greater range and fewer refuelling stops, reducing "range anxiety".
This extra capacity translates to increased flexibility and reduced stress during journeys. Riders won't need to worry about constantly seeking out gas stations and can be more selective about where they stop to refuel. This is especially beneficial when travelling on highways or in areas where gas stations may be inaccessible or scarce.
Additionally, a larger fuel tank can help prevent issues stemming from low fuel levels. While modern fuel pumps are more resistant to issues caused by low fuel, consistently running a vehicle with low fuel levels can lead to problems with the fuel pump, fuel filters, and engine performance. A larger tank reduces the frequency of riding with low fuel levels, thereby mitigating these potential issues.
Installing a larger fuel tank, such as the MT-09 Tracer's tank, can be a DIY project, but it requires careful planning and execution. It's important to ensure that the tank is compatible and that all necessary parts and tools are available before beginning the installation process.

The MT-09 fuel tank is the same design as the FZ tank
The FZ-09, on the other hand, has a larger fuel tank capacity of 17 litres, which provides a notable advantage in terms of riding distance. This has sparked discussions among riders considering modifications to improve their MT-09's range. Some have contemplated fitting their MT-09 with the larger Tracer tank, which offers a capacity of 17 litres, to address the issue of frequent refuelling stops.
While the feasibility of this modification has been questioned, it is believed that the Tracer tank is designed to work with the MT-09's motor, increasing the likelihood of a successful swap. However, it is important to note that such modifications should be approached with caution, as they may involve complex procedures and potential safety risks.
In conclusion, while the MT-09 fuel tank shares a similar design with the FZ tank, the option of installing a larger Tracer tank presents an intriguing prospect for riders seeking extended riding distances without the inconvenience of frequent refuelling.

The FZ-10 tank may fit the FZ-09, but it's unknown if it's a simple swap
The Yamaha MT-09 is a popular bike, but some riders are put off by its small fuel tank capacity of 14 litres. The FZ-10, with its 17-litre tank, seems like a perfect solution, but can the FZ-10 tank be fitted onto the MT-09?
It is unclear whether the FZ-10 tank is a direct swap for the MT-09's tank. One forum user has suggested that the MT-09 Tracer tank, also 17 litres, is "built to work with this motor, so is more likely to fit than the FZ-10." However, they go on to say that they have "never heard of anyone doing the swap... so it may not be simple."
Another user on the same forum thread mentions that someone has started an FJ swap, but that the project has been shelved. This suggests that swapping the fuel tank on the MT-09 is possible, but it may be a complex process.
While there is no clear answer on the FZ-10 tank fitting the MT-09, there are other methods to increase the bike's range. One user has suggested punching an air hole into the filler neck to gain a little more capacity. Another user has drilled 8mm vent holes into the internal filler neck, allowing for a few hundred millilitres of extra fuel.
The MT-09 is a bike that has captured the hearts of many, and with some modifications, it can be made to go the distance.

You can increase the FZ-09's fuel capacity by punching an air hole in the filler neck
The Yamaha MT-09 is a popular motorcycle, but some riders are unhappy with its fuel capacity. The bike's 14-litre tank can feel limiting, especially when compared to the 17-litre tank of the FZ-10, which allows for a comfortable 300-350 km range.
There are a few ways to increase the fuel capacity of the MT-09. One method is to modify the filler neck by punching an air hole just below the gas cap. This simple modification can increase the tank's capacity by 0.5 to 0.7 gallons, providing an extra 20+ miles before needing to refuel. This modification can be done in a few simple steps. First, the tank is removed, drained, and left to air out. Then, a tool like a Dremel with a cutoff wheel is used to cut a slot or a few small holes on the right side of the filler neck, just below the top flange. This allows the trapped air to escape, enabling the fuel level to go almost to the top of the tank.
It is important to note that this modification should be approached with caution, as sparks and gasoline can be a dangerous combination. Some riders have suggested using a sharp, long punch to create the holes, while others have recommended using a wet towel to cover the tank during the process. Additionally, it is advised not to fill the tank to the brim after this modification, as the expanding fuel can overflow out of the vents and create a safety hazard.
Another possible solution to increase the fuel capacity is to consider a tank swap. The FZ-09 Tracer tank has a capacity of 17 litres, and it may be possible to fit this larger tank onto the MT-09. However, this swap has not been commonly done, and there are no confirmed reports of its success.
While the MT-09's fuel capacity may be a drawback for some riders, these modifications and potential workarounds can help extend the bike's range and improve the riding experience.
