Royal Enfield interceptor 650 vs Duke 390 – Engine performance

Bikers rave at the Duke 390 engine saying it is indeed ‘ready to race’ like the KTM slogan goes. It is powered by a single cylinder, 370 cc, liquid cooled engine producing 43 bhp / 37 Nm of torque. The engine is a high-compression unit, energetic with plenty of mid-range and top end power. With such a light weight, space frame chassis, it feels like a Duke 390 modified for racing. Acceleration is immediate and you can take the bike to the limit even on corners, that’s how stable it feels. The Duke 390 top speed is 160 km/h and 0-100 km/h times could leave much larger bikes trailing in the dust. The Duke 390 mileage per liter is 26 km while the Interceptor is less frugal at 23 kmpl.

The Royal Enfield Interceptor 650 is more relaxed in its approach. Yes, it has twin-cylinders with a total capacity of 650 cc, but those 47 horses and 52 Nm of torque come with the added weight of the heavy chassis and body work. Acceleration and top speed are still comparable to the Duke 390, but the Interceptor has more low-end torque which gives the rider an effortless thrust every time the throttle is opened. The Royal Enfield feels civilised and composed as you would expect from a big street cruiser.

The KTM’s engine can best be described as a hooligan while the Interceptor is more of a gentleman. If you love to red line your bike at every opportunity then the Duke is your choice. The Interceptor is better suited for long distance journeys which call for serious mile munching. It should be noted that the KTM Duke 390’s engine is liquid cooled, and some owners have complained about heating issues, whereas the Interceptor is air/oil cooled which also could be a problem in heavy traffic at slow speeds. However, both bikes should perform well in city driving without any issues.

Interceptor 650 vs Duke 390 – Ride and handling

The Duke has a sporty riding posture that compliments its aggressive engine characteristics, urging the rider through high-speed manoeuvres. On the other hand, the Interceptor is more laid back, with a comfortable position, better suited for a relaxed ride. Wide handlebars on the Enfield offers a stress-free ride, combined with a large, flat seat and forward set foot pegs. The Duke’s low handlebars and rear set foot pegs can get a little uncomfortable for daily commutes.

If you are thinking of tagging along with a pillion rider, then the Interceptor is perfect with its accommodating seat and sorted ergonomics. With the Duke, the pillion is seated too high and there’s just not enough space. Tall riders will struggle on the Duke 390.

With a forward stance on the Duke 390, it handles quite well due to more weight up front. The Duke 390 weight is only 170 kg which makes it easy to park and move around at slow speeds. The Interceptor is nearly 40 kg heavier making it difficult to manage through tight spaces, but this weight disappears once you get going. Duke 390 mileage is higher than the Interceptor due to its lower kerb weight.

The Duke 390 comes with stiff suspension that provides good handling and dynamics, but this offers a harsh ride, especially over bumps and potholes. The Interceptor’s suspension set up is much softer, allowing it to soak up uneven roads with aplomb and giving the rider a comfortable biking experience. Duke 390 seat height is 822 to 830 mm, riding higher than the Interceptor 650 which is at 804 mm, allowing shorter riders a better chance at reaching the ground on the cruiser.

However, both machines offer unbridled fun on the road, something you won’t find on most motorcycles in this price range.
