Royal Enfield Himalayan 450 vs Guerrilla 450: Mileage Explained

The Royal Enfield Himalayan 450 and the Guerrilla 450 are chips from the same block, literally and figuratively. However, their purposes are quite different and it is quite evident in the way they are manufactured and the equipment they receive.

But first, let’s take a look at what they have in common – a single-cylinder liquid-cooled 450cc ‘Sherpa’ engine – the first of its kind from the brand. It has 40.02 PS at 8000 rpm and 40 Nm at 5500 rpm. The 450 siblings also get a 6-speed gearbox with slipper clutch and assist. And that’s where the powertrain similarities between them end, at least on the spec sheet.

With all that the Himalayan 450 has, its ARAI claimed mileage is 30 kmpl (28.5 kmpl as per WMTC (World Motorcycle Test Cycle)). However, in our real-world test, the ADV returned a mileage of 29.54 kmpl in the city and 31.87 kmpl on the highway – quite close to what the ARAI claimed figure is.

However, Royal Enfield is yet to declare the ARAI declared mileage of the Guerrilla 450 but says it returns a mileage of 29.5 kmpl as per WMTC. There are few reasons why the GRR gets better mileage than the Himmy.

For starters, at 185kg (board), it’s 11kg lighter than the ADV. Second, RE tweaked the Himalayan’s engine tuning, and also tweaked its gearing (45-tooth pinion versus 47-tooth on the Himalayan), to suit the roadster’s nature.

Since the Guerrilla is said to have been “optimized for cruising speeds,” it should be more relaxed on the highway compared to the Himmy. That means you wouldn’t be wrong to expect the Guerrilla’s engine to rev lower than the Himalayan’s for the same speed. This should result in increased fuel efficiency on the Guerrilla. With that, we can deduce that the actual expected mileage of the Guerrilla is between 30 kmpl and 33 kmpl. With an 11-litre fuel tank, it should have a real range of around 250-260km before you start looking for the nearest gas station.
