Royal Enfield decided to unveil its latest engine - a 650 cc parallel-twin - at its UK Technology Centre near Leicester in the UK, just a few days short of the official unveil of possibly two new bikes at the EICMA show in Milan on November 7. As reported earlier, the new engine is indeed a 650 cc parallel-twin, and not a 750 cc twin, as has been widely speculated and reported. The brand new parallel twin engine will be Royal Enfield's most powerful engine, and the 648 cc, air-cooled, parallel-twin engine makes 47 bhp at 7100 rpm and 52 Nm of peak torque at 4000 rpm, and is mated to a six-speed transmission.

 

The new engine employs an air cooler, and four valves per cylinder with a single overhead cam. According to Siddharth Lal, CEO, Royal Enfield, the engine revs to about 7500 rpm and is capable of reaching 80-90 mph (130-140 kmph) with ease. Also new is a balancer shaft which is said to reduce vibrations. The engine has been conceived at the UK Technology Centre, but was jointly developed with technicians in Royal Enfield's headquarters in Chennai, Lal added. The new engine will be a single spec engine which will be used in the new bikes positioned as Royal Enfield's global products. The new bikes with the 650 cc engine will be higher spec motorcycles, and the same bikes can be marketed across India, US, Europe, Colombia, Brazil and South East Asia as well.
