Royal Enfield Himalayan 450 specs leaked ahead of reveal

A homologation document has given us key details for the new Himalayan ‘452’ including engine size and power

With the reveal of the all-new Royal Enfield Himalayan 450 looming, a leak has provided us with numerous details about the bike. 

Asian website RushLane has gotten hold of a copy of the homologation document, which lists the engine capacity as 451.65cc. The document also notes that the engine produces 29.44kW (39.5bhp) at 8,000rpm. 

Interestingly, the bike is homologated as a ‘Himalayan 452’, matching the (rounded up) engine capacity. We can’t yet be sure if that’s the name the new Himmy will be marketed with - such a move would match what Royal Enfield has done with the Scram 411, but the company may still go for Himalayan 450. We’ll have to wait and see.

The leak has also provided us with some measurements. The bike will be 2,245mm long with a 1,510mm wheelbase, and 852mm wide. The height is 1,316mm as standard, or 1,415 if the optional taller screen is specced. All of that makes the Himalayan 450/450 longer and taller than a KTM 390 Adventure, but a little narrower. 

Royal Enfield Himalayan 450/452 image leak

A few weeks ago, we had our clearest pictures yet of the bike, after RushLane had acquired some images, taken while one of the new machines was being stored. The bike was parked up next to a row of what looked like Super Meteor 650s and the pics did give a very clear view of the new machine.

For one, this isn’t a clean sheet design that is going to take the Himalayan concept away from its roots, and we sort of knew that anyway. The styling of the bike is very much a case of evolution, not revolution. The fuel tank is new, though, and seems much larger than the peanut-style tank on the old bike. 


It is also the first clear view we can get of the new water-cooled 450 motor and, as you’d expect for such a drastic change from before (the previous bike has a 410cc air/oil-cooled unit), it’s a totally different looking beast. At first glance, the right-side engine casing looks very much like the item found on J-series powered bikes, like the Hunter 350 and Meteor 350. Removing the cooling fins from the motor has also given it a more up-to-date look (compared to the cooling fins before), and that almost feels like it lifts the overall look of the bike.

Another change is a move to a TFT dash which is really no surprise. There are a load of new models in the Royal Enfield range featuring a TFT, and given that this should give the bike turn-by-turn navigation - a must on a modern adventure bike - it really can only be a good thing.

About the only other thing we can glean from the images is that the chassis of the new bike features proper USD forks, not the telescopic items found on the old machine. We can’t tell if there is any adjustability at the front, but they are hefty-looking forks, between 43 and 45mm is our best guestimate.

These details add to previous ones, including a 21-inch front wheel and 17-inch rear wheel, and a single rear shock. Dual-channel ABS has also been rumoured, as well as a ride-by-wire throttle. 

Royal Enfield 450/452 release date

1 November is set to be the go-live date, confirmed by Royal Enfield. That means our first chance to see the bike in-person will likely be at the EICMA show in Milan in the second week of November and, as ever, Visordown will have boots on the ground to bring you all the news as it happens.

Royal Enfield Guerilla 450

It has also become clear, as reported by Motociclismo, that the Himalayan 450 will not be the only new bike from the Indian brand to use the single-cylinder 450cc engine. The registration in India of the name 'Guerilla 450' would suggest another bike, presumably a derivative of the Himalayan, is also on the way.

The word 'guerilla' can be used in a number of contexts, but is perhaps best associated with outnumbered resistance fighters repelling large invasion forces, using irregular strategies and making the exploiting their knowledge of the terrain to attempt to overcome the invaders. Its use in the context of naming this motorcycle would suggest it to be more off-road-oriented than the Himalayan, but there are no solid technical details available yet - of course we are still almost two months out from the launch of the Himalayan 450 itself.
