Indian motorcycle manufacturer Royal Enfield launched its all-new 650 twins in India earlier this month. Both the Continental GT 650 and the Interceptor 650 are powered by the same 648cc parallel twin engine. While Royal Enfield has revealed the official power and torque figures, Cycle World decided to put those numbers to the test by putting the Continental GT 650 on a dyno.
The tester from Cycle World puts the motorcycle on the dyno and then starts the procedure of checking the relevant details required as he twists the throttle and lets the Continental GT 650 pull through the revs on the rolling road. The Continental GT 650’s final figures at the wheel come out to be 44.36 Bhp at 6,840 rpm and 51.91 Nm of torque at 5,100 rpm. Both the figures mentioned here are at the wheel.
According to Royal Enfield, the Continental GT 650 is powered by an oil and air-cooled fuel injected engine. The parallel twin motor is paired with a 6-speed gearbox. According to Royal Enfield’s official figures, the Continental GT 650’s SOHC parallel twin engine produces 47 Bhp at 7,250 rpm and 52 Nm of torque at 5,250 rpm. Royal Enfield also claims that around 80 per cent of the torque produced by the engine is delivered as low as 2,500 rpm.
The engine features a single piece, weighted balancer shaft that fires with a 270-degree degree firing angle which helps balance out most of the vibrations, something that has plagued the brand’s single cylinder motorcycles.
While the tested numbers from the Dyno are different from the official figures handed out by Royal Enfield, prospective owners need not to worry. The numbers given out by Cycle World’s Dyno testing are those measured at the wheel of the bike whereas Royal Enfield has given power and torque figures measured in at the crank.
With around 10 per cent of power from an engine from crank to wheel, the figures of Cycle World and Royal Enfield are a now seem to be one and the same. However, what puzzles us is the fact that during testing, the Continental GT 650’s peak power comes in at around 500 rpm lower than the company’s claims. So this is either a glitch or an anomaly or the Continental GT 650 is allowing owners faster access to the available power.
All said and done, the dyno figures for the Royal Enfield Continental GT 650 are very impressive indeed. Previously, it was not uncommon for Royal Enfields to suffer up to 30 % power loss from the crank to the wheel. Now though, the company has managed to bring this figure down to under 10 %, which is a huge improvement. This also goes on to show why the twins are so quick, and are able to do good speeds.
Almost everyone who have ridden the Royal Enfield Interceptor 650 and Continental GT 650 motorcycles have nothing but praise for them. Seen a huge improvements over existing Royal Enfield motorcycles, these bikes are expected to expand the market significantly. The sharp price tags on both motorcycles are meant to do just that. Bookings are now open, with deliveries slated to start from early next year.
