How Much Power Does the 2022 Royal Enfield INT650 Make?

Running RE’s 650 Twin on the Cycle World dyno.

The Royal Enfield INT650, or “Interceptor” as it is known outside of the United States, is a British-designed, Indian-built roadster that blends classic authenticity and charm with modern-day performance. It’s one of two 650 twins offered by Royal Enfield, the other being the Continental GT cafe racer.

The INT650, like the Continental GT, is powered by a SOHC air/oil-cooled eight-valve 648cc parallel-twin engine with a 270-degree crankshaft. Modern touches are scattered throughout, like valve rocker arms that use rollers on the cam side and screw/locknut adjustable tappets on the valve side, for less friction and ease of maintenance, and a power assist/slipper clutch. Of course, the twins are fueled by electronic throttle bodies. Smooth, crisp delivery and a mighty fun balance of power give it satisfying real-world performance.

Horsepower and torque figures of the 2022 Royal Enfield INT650 recorded on the Cycle World dyno.Robert Martin Jr.

In anticipation of our upcoming review of the 2022 INT650, we strapped it to Cycle World’s Dynojet 250i dynamometer to get horsepower and torque figures. The INT650 produced a modest 40.90 hp at 6,780 rpm and 37.35 lb.-ft. of torque at 5,100 rpm. Not earth-shattering, by any means, but you can see the aforementioned smoothness on its charts. Roughly 34 pounds of torque is readily available from 2,500 rpm, with a relatively flat torque spread following. All this adds up to linear power delivery, which translates to everyday flexibility.
