The Yamaha MT-125 can be suitable for long rides, but it has some limitations. It offers a comfortable riding position with minimal vibrations, especially through the seat, handlebars, and pegs, which is beneficial for reducing fatigue. The bike's design, including its upright seating position and well-arranged handlebars, helps in reducing rider fatigue during longer journeys. However, taller riders might find the seat and riding position a bit cramped, particularly after around 45 miles of riding. The MT-125's fuel efficiency is a significant advantage, with an average fuel consumption of around 134 mpg, allowing for a range of over 200 miles per tank. This makes it economical for long commutes. The bike's stability at higher speeds, up to around 80-85 mph, and its smooth handling characteristics, thanks to the upside-down forks and Michelin Pilot Street tires, also contribute to its suitability for longer rides. Despite these positives, some riders may find the hard seat and the lack of space to move around on the saddle to be discomforting over extended periods. Therefore, while the MT-125 is capable of handling long rides, it may not be the most comfortable option for all riders, especially those who are taller or prefer more spacious seating arrangements.
