During an introductory visit to the brand new Royal Enfield UK Technical Center at Bruntingthorpe, near Leicester in the UK, Royal Enfield revealed their new engine, a 650cc parallel twin. The new parallel twin engine will power two motorcycles that are expected to debut at the EICMA show, also known as the Milan Motorcycle Show shortly. Royal Enfield say the motorbikes are at the pre-production stage and assumes them to be ready for the market by 2018, April. Royal Enfield says the roll out of the motorcycles will be spread over the calendar year 2018 for all of its markets but India is expected to be amongst the first markets. The new motorbikes, guess is that the Interceptor name will be used, will be Royal Enfield’s first ever international all-new motorbikes.
The new Royal Enfield 650cc parallel twin
The new engine’s detailed specification was not revealed today. However, we do have the final power figures. The 4-valves per cylinder SOHC fuel-injected engine will make 47PS of peak power at 7,100rpm and 52Nm at 4,000rpm. Compression in a reasonable 9.5:1. Royal Enfield re-iterated that the power output and its expansion was not one of the objectives for the engine. The exact displacement is 648-cc with an oversquare configurations. Royal Enfield says the engine needed to be fast enough to be a solid upgrade to the current produce range but not so fast that it would intimidate new riders. Inasmuch, Royal Enfield thinks the new clients for the 650 twin to be a mix of present clienteles advancement, brand aficionados who haven’t found a bike they can buy so far (a specific example quoted was European riders who cannot sit at motorways speeds on present Enfield), new prospects as well as people who would normally have purchased something else. CEO Royal Enfield Siddhartha Lal publicized that the original engine was planned as a 600-cc twin that was later ‘grown’ to 650-cc to guarantee that the new motorcycles would cross the ton 100mph, or 160kmph easily.
Royal Enfield also made sure we understood that this engine is designed to appeal both to new and experienced riders and one of the ways to do that was to produce a fat and steady torque curve.
The new engine is also completely armed in other ways. The engine cases take inspiration is visual form from the old 1948 500 Twin says product strategy and industrial design head Mark Wells. But inside is a modern air-cooled engine with an oil cooler mounted high and center. The engine gets a six-speed gearbox as well as a slip-assist clutch to reduce lever effort. While more details were not exposed, Royal Enfield did reveal that the motorbike will cruise the British motorways at 70-80mph or 120-135kmph easily.
Royal Enfield has decided to reveal more of the details of the motorcycle only at EICMA. But we were told evidently that the chassis is all-new and in fact, Simon Warburton, head product growth said, “Only a few screws, if that, are interchangeable with the old models.” We had a prototype do a fast fly-by that showed a pair of gas-charged rear shock absorbers. Royal Enfield also confirmed that ABS will be on the motorcycle – it is safe to assume this means in India as well since the launch is expected for April. The other model on display, revealing on a genuine accessory front alloy wheel also showed off a single disc and telescopic forks – but that isn’t new information.
While not officially confirmed increasingly convinced that Royal Enfield will have twin twins on the show stands at EICMA. The prototype in the fly-by had a raised street-style handlebar but a Continental GT-style cafe racer has also been spotted testing. It is these 2 forms of the new platform that we should see the Milan Motorbike Show. Naturally, this engine and version of the frame together will also underpin future motorcycles from the Chennai brand.
