What does “3-valve engine” mean on the TVS TVS NTORQ?

The TVS NTORQ comes with a 3-valve 125 CVTi - Revv engine with two intake valves and one exhaust valve. This additional intake valve allows the air-fuel mixture to enter the combustion chamber more efficiently, helping the engine deliver quicker response, smoother acceleration, and stronger performance on inclines.

Why do some scooters still use 2-valve engines if 3-valve engines are better?

2-valve engines are still used as they are mechanically simpler and cheaper to produce. Whereas 3-valve engines are designed to improve airflow and combustion efficiency. For riders who mainly use scooters to run errands, 2-valve engines still offer dependable everyday performance without adding complexity.

Does the TVS NTORQ’s 3-valve engine affect top speed or acceleration?

Yes. The 3-valve 125 CVTi - Revv engine in the TVS NTORQ improves airflow into the engine, allowing combustion to happen more efficiently. This helps the scooter deliver quicker throttle response, stronger mid-range acceleration, and better momentum retention while climbing flyovers or riding with a pillion.

Is fuel economy affected by the 3-valve engine compared to 2-valve designs?

The 3-valve configuration in the TVS NTORQ is designed to optimise combustion efficiency rather than simply increase performance. By allowing a better air-fuel mixture, the engine delivers responsive acceleration and consistent rideability while still maintaining practical fuel efficiency for everyday city commuting.
