What You'll Learn

The Yamaha XT225's fuel line is 5/16
The Yamaha XT225 is a dual-sport motorcycle that was produced from 1986 to 2007 and is known for being a lightweight, dual-purpose motorcycle. The Yamaha XT225's fuel line is 5/16". This refers to the inner diameter of the fuel line, which is an important measurement to consider when replacing or upgrading fuel lines.
A 5/16" fuel line is a common size for many motorcycles, including the Yamaha XT225. It is important to have the correct fuel line size to ensure the proper flow of fuel from the tank to the engine. A fuel line that is too small can restrict fuel flow, leading to poor engine performance. Conversely, a fuel line that is too large can result in fuel leaking or spilling.
The Yamaha XT225's fuel line size of 5/16" is designed to work optimally with its 223cc single-cylinder, air-cooled four-stroke engine. This engine features a SOHC (single overhead camshaft) configuration and produces 15 kW of power and 19 Nm of torque. The 5/16" fuel line ensures that the engine receives the correct amount of fuel, contributing to the bike's overall performance and efficiency.
When considering fuel line sizes, it is also important to think about the material and quality of the fuel line. Yamaha XT225 owners may want to upgrade their fuel lines to high-quality alternatives that are more durable and resistant to swelling, UV light, hardening, and cracking. By choosing a fuel line with a five-layer Greenshield® Barrier Technology, Yamaha XT225 owners can benefit from reduced vapor loss, improved fuel efficiency, and enhanced environmental safety.

The fuel line is compatible with multi-fuels
The Yamaha XT225 is a beginner-friendly bike with a 223cc SOHC, air-cooled, single-cylinder engine. It is mated to a 6-speed transmission and a wet multi-disc clutch, making it a smooth and non-intimidating ride. The fuel line on this bike is compatible with multi-fuels, including unleaded gasoline, methanol, and ethanol (E10, E15, and E85). This versatility in fuel compatibility offers convenience and flexibility to the rider.
The fuel line's compatibility with multi-fuels is a significant advantage, especially when considering the availability and accessibility of different types of fuel. With this bike, riders are not restricted to a specific type of fuel and can easily adapt to their fuel source, whether it's unleaded gasoline, methanol, or ethanol. This is particularly useful when travelling in areas where fuel options may be limited or when experimenting with alternative fuels.
The multi-fuel compatibility of the Yamaha XT225's fuel line is achieved through its innovative design and high-quality materials. The fuel line incorporates a five-layer Greenshield® Barrier Technology, which includes a barrier tube, a Greenshield® barrier, an adhesion layer, a reinforcement layer, and a cover. This combination provides exceptional heat and corrosive liquid resistance, ensuring the fuel line can handle various fuel types without leakage or damage.
The Greenshield® barrier, a key component in the fuel line's construction, is a patent-pending technology that offers the lowest permeation in the industry. It creates a strong barrier against fuel vapour loss, making the bike fuel-efficient and environmentally friendly. The reinforcement layer, made of spiral textile, adds strength and pressure resistance, further enhancing the fuel line's ability to accommodate multi-fuels.
Additionally, the Yamaha XT225's fuel line is designed with a temperature range of -40°C to +125°C (-40°F to +257°F) in mind. This wide temperature range capability ensures that the fuel line can withstand extreme conditions without compromising its performance or integrity. The HNBR tube, thermoplastic barrier, and CPE cover work together to provide oil, heat, ozone, and abrasion resistance, contributing to the fuel line's durability and compatibility with multi-fuels.
