Royal Enfield 650cc Engine Revealed – Will Power Many Motorcycles In The Future

Royal Enfield 650cc Engine Revealed and is as powerful as 400cc that are available in the market right now

Royal Enfield unveiled its first modern twin-cylinder engine at its new Technology Centre in Leicestershire, England, today. This new 650cc, air cooled parallel twin will power the newest generation of Royal Enfield motorcycles.

650cc twin engine was developed to use as a global platform. The engine will offer broad spread of torque which will make the motorcycle easy to ride without frequently shifting gears. The new platform is a 4 stroke, single overhead cam, air-cooled, 648cc parallel twin cylinder engine developed by Royal Enfield’s UK Technology Centre and Chennai teams. Engineered to be able to accelerate and deliver higher power and torque at lower RPMs, this new engine has an output capability of 47bhp and 52Nm torque.

The engine maintains an under-stressed 9.5:1 compression ratio and the fuel injection system. The focus of the development was on giving adequate torque, spread broadly throughout the rev range so that riders can tap into it instantly at any time. There is a single-piece forged crankshaft (a first for Royal Enfield) which ensures strength and the ability to handle the twin’s torque. This crankshaft uses a 270-degree firing order, which gives a high degree of character to the engine’s power delivery. Also, thanks to the use of a balancer shaft, unwelcome vibrations have been eliminated.

The motor retains Royal Enfield’s ‘air-cooled’ engine legacy, which leads to a simple, cleaner look with fewer components and less weight. Using ambient air-flow combined with engine oil to keep engine temperature at an optimal level means that a radiator, fan, hoses, and other components are unnecessary. This keeps the motor beautifully clean and essentially pure, like the experience it provides.

Just as relevant as the engine’s individuality, is its sound. The characteristic ‘thump’ of Royal Enfield’s singles is gone and now resulting in twin silencers that rumble with just the right tone. The entire platform, including the engine and chassis have undergone rigorous testing during the development programme. It has been subjected to lab and bench tests, in addition to being tested on proving grounds, race tracks and public roads.
