Yamaha FZ25 Specifications

The Yamaha FZ25 is a standard/naked motorcycle produced by Yamaha Motor Company. It is powered by a 249cc, single-cylinder, fuel-injected engine that is capable of producing approximately 20 horsepower. The Yamaha FZ25 has a maximum torque output of 20 Nm (14.75 ft-lbs) at 6,000 rpm. The FZ25 features a 6-speed manual transmission and has a top speed of around 115 km/h (71 mph). It has a fuel capacity of 14 liters (3.7 gallons) and a fuel consumption rate of around 45 miles per gallon. The motorcycle has a dry weight of approximately 148 kg (326 lbs) and is designed for use on paved roads. It is a popular model in countries where it is sold and is well-regarded for its performance and reliability.

The seat height of the Yamaha FZ25 is 795 mm (31.3 inches). This is the distance from the ground to the top of the seat, and it is an important factor to consider for riders who are shorter in stature. A taller seat height may make it more difficult for shorter riders to reach the ground with their feet while stopped, which can affect their balance and confidence while riding. On the other hand, a lower seat height may be more comfortable and easier to manage for shorter riders. It is always a good idea to sit on a motorcycle and get a feel for its seat height before making a purchase, especially if you are on the shorter side.

The Yamaha FZ25 is equipped with a 100/80-17 front tire and a 140/70-17 rear tire. These tires are tubeless and are mounted on 17-inch wheels. The front tire has a width of 100 millimeters and a aspect ratio (height to width) of 80%, while the rear tire has a width of 140 millimeters and an aspect ratio of 70%. The tire size is a combination of the width, aspect ratio, and wheel size, and it is important to use the correct size tire for your motorcycle to ensure proper fit and performance. The tire size for the Yamaha FZ25 is optimized for its specific weight, power, and handling characteristics, and it is recommended to use tires of the same size when replacing them.

The oil capacity for the Yamaha FZ25 is 1.1 liters (1.16 quarts). This is the amount of oil that the motorcycle’s engine requires to function properly and maintain its performance and longevity. The oil change interval for the Yamaha FZ25 is typically every 6,000 to 8,000 kilometers (3,728 to 4,971 miles), depending on the specific operating conditions of the motorcycle.
