File:A tribute to the 'Royal Enfield Himalayan'.jpg

The Himalayan is an adventure motorcycle manufactured by Royal Enfield, premiered in February 2015 and launched in early 2016. Pierre Terblanche led the design team during Himalayan's development. The Himalayan differs considerably from the other motorcycles offered by Royal Enfield - most of which are various incarnations of the Bullet utilizing the same frame and engine - in terms of its chassis and powertrain. Pierre Terblanche, formerly of Ducati and Moto Guzzi among other companies, headed Royal Enfield's design team during development of the Himalayan. An early prototype was made in mid-2014, followed by a more complete version in 2015. Engine The Himalayan's engine was designed and produced by Royal Enfield from the ground-up and shares little to no parts with other contemporaries in the company's line-up. The engine, named the LS410 indicating its long-stroke stroke ratio, is a unit-construction 411 cc single-cylinder, oil-cooled 4-stroke SOHC engine. The motor generates a power output of 24.5 bhp@6500 rpm (18.02 KW) and a maximum torque of 32 Nm@4000-4500 rpm. The engine also includes an oil cooler, a first among motorcycles manufactured by Royal Enfield India. Fuel is supplied to the engine via carburettor in the Indian market, and via electronic fuel injection for other world markets, likely due to emissions regulations. The engine is mated to a 5-speed constant mesh transmission. This engine features a single overhead camshaft, thereby moving away from the traditional push-rod design that had been used by the company from 1955, starting with the original Bullet up to the contemporary Classic series.

Frame and Chassis The Himalayan features a half-duplex split cradle frame. Suspension is telescopic in the front while the rear is provided with monoshock suspension. Front forks are 41 mm with 200 mm of travel and the rear suspension offers 180 mm of travel. The motorcycle has a ground clearance of 220 mm. Stock tires measure 90/90 21-inch at the front and 120/90 17-inch at the rear. These are manufactured by CEAT. The motorcycle has a 300 mm disc with a dual piston floating caliper at the front and a 240 mm single piston caliper disc at rear. The instrumentation console for this motorcycle is also modeled anew. It includes an analog speedometer and tachometer, with a digital display for the odometer, gear position indicator, trip-meter and engine temperature gauge. Also included is an analog fuel gauge and a digital compass. Also included is a windscreen, which can be manually adjusted for height via screws to two positions.
