Introduction

The Yamaha XSR 155 engine performance is what truly defines this neo-retro roadster. Built on Yamaha’s proven R15 platform, the XSR 155 blends heritage-inspired design with cutting-edge performance tech, offering a perfect mix of style, speed, and everyday usability for Indian riders.

VVA Technology: The Secret Behind the Punch

At the heart of the XSR 155 lies a 155cc liquid-cooled, single-cylinder, SOHC engine equipped with Variable Valve Actuation (VVA).
This smart system ensures smooth power delivery across rev ranges – torque at low RPMs and thrilling top-end at high speeds.

Key Highlights of the XSR 155 Engine:

• Displacement: 155cc, liquid-cooled, 4-valve
• Max Power: 18.4 PS @ 10,000 rpm
• Max Torque: 14.2 Nm @ 7,500 rpm
• Transmission: 6-speed gearbox with assist & slipper clutch
• Fuel System: Electronic fuel injection

This VVA setup automatically switches between two cam profiles for optimal combustion efficiency, allowing the XSR 155 to deliver power that feels both refined and responsive.

Real-World Performance and Ride Feel

Riders describe the Yamaha XSR 155’s performance as effortless yet exciting. It pulls cleanly from low revs and rewards you when pushed hard – very similar to its sibling, the R15, but with a more relaxed riding posture.

• 0–60 km/h: Approx. 4.5 seconds
• Top Speed: Around 130 km/h
• Mileage: 45–50 km/l (depending on riding style and conditions)

The bike’s balance of fuel efficiency and performance makes it a practical choice for both city rides and weekend highway runs.

Design Meets Performance

While the engine’s DNA screams sportbike, the XSR 155’s design speaks vintage – a round headlamp, teardrop fuel tank, and classic seat. But beneath that retro skin lies a thoroughly modern machine that’s as capable as it looks cool.

This is where Yamaha nails the emotional connect: nostalgia for the old-school meets the thrill of new-age performance.
