What is the top speed of the Yamaha 155?
4 Answers
Yamaha 155 can reach a top speed of 120km/h. The Yamaha 155 is equipped with a signature single-cylinder four-valve 155cc liquid-cooled engine, along with an automatic start-stop system, smart ignition, and a keyless entry system. Introduction to Yamaha 155: Exterior: The Yamaha N-MAX155 features a relatively wide body, providing rare wind resistance protection to effectively enhance comfort. It incorporates some sporty elements with a well-balanced dot-line design that reduces the sense of heaviness at the rear. The lightweight lines bring a sporty feel, and the position of the split turn signals has been adjusted with a reduced size. Performance: The Yamaha N-MAX155 is powered by a 155cc single-cylinder liquid-cooled engine. Thanks to the advantages of electronic fuel injection, it offers smooth acceleration and a comfortable feel, with a peak torque of 14 Nm and a maximum horsepower of 15Ps.
I recently tested several Yamaha 155cc motorcycles, such as the R15 V4 model. Their top speeds typically range between 130 to 140 kilometers per hour, but this depends on specific conditions. On a flat road with minimal wind and a lighter rider, you might hit 138 km/h without issues; however, with poor maintenance, a dirty air filter causing insufficient engine air supply, it could drop to 125 km/h. Wind resistance plays a huge role—tucking in reduces drag, but safety comes first. I never recommend pushing top speeds on public roads, as emergency braking could lead to crashes. Regular maintenance is crucial—proper chain lubrication and adequate tire pressure help maintain stable acceleration. But don’t just chase speed; enjoying the ride is what truly matters.
I've been riding my Yamaha 155 for quite a while now. On the highway, I've tested its top speed, usually reaching around 135 km/h, slightly higher on good weather days. Lighter riders go faster, but I'm of average build, and with a tailwind, I've hit 137 km/h. However, going too fast isn't safe—the wind howls, the bike feels unstable, and fuel consumption skyrockets—once you exceed 110 km/h, it burns fuel like pouring water. I make it a habit to keep the bike clean, like regularly cleaning the air filter to ensure better performance. Speed isn't the goal; riding steadily and enjoying the scenery is what makes it comfortable. Checking the chain before every ride is a must—don't let it get loose and hold you back.
I think the Yamaha 155's top speed is around 135 km/h, but don't just chase that number. Safe riding is more crucial—higher speed means longer braking distance and harder cornering control. From my experience, a well-maintained new bike can steadily reach 130-140 km/h, but strong winds or rain immediately drop it below 120. Maintenance-wise, chain adjustment and oil changes play a big role. Better focus on honing your riding skills and wearing proper helmets and gear—that's far wiser than taking risks.
