Royal Enfield unveils new 650cc twin-cylinder engine

  •  

Royal Enfield has unveiled a new 648cc, twin-cylinder engine that will power its future bikes. The engine was revealed at the bike maker's new Technology Centre in Leicestershire, England.

The 648cc, 4-stroke, parallel-twin cylinder, air-oil cooled engine was jointly developed by Royal Enfield's Technology Centre and its engineers in Chennai. The engine produces 47 BHP @ 7,100 rpm and 52 Nm of peak torque @ 4,000 rpm. It uses a fuel injection system, a single-piece forged crankshaft and a balancer shaft. It is paired with a 6-speed transmission.

The engine has been styled along the lines of the classic air-cooled engine with cooling fins and features twin exhaust pipes. Royal Enfield claims that the combination of ambient air flow and engine oil helps maintain optimal engine temperature and hence, the engine does not require a radiator.
