The bike was designed at Royal Enfield's Technology Centre at
Bruntingthorpe Proving Ground in
Leicestershire, England. Both models, Interceptor and Continental GT, share the same engine, frame, suspension, wheels, brakes, exhausts and mufflers. The engine is a
wet-sump, 648 cc, air/oil cooled
SOHC,
8v,
parallel twin. Fuelling is via Bosch injection and engine management. The low 9.5:1 compression ratio will help the engine tolerate lower-octane fuel. The crankshaft has a
270° Crank, with a gear-driven balance shaft ahead of the crank. The
slipper clutch drives a six-speed gearbox and chain final drive. The cylinder head receives substantial
oil-cooling and the bikes have a large oil cooler on the frame downtubes. Producing a modest 46.80bhp @ 7250 rpm, the engine is capable of future development:
Bike magazine reported that "the crankshaft's substantial bearing area and the hefty alloy crankcases suggest that the engine could comfortably deliver more power. Compression, capacity and revs could be raised on future models". The chassis is a tubular twin-downtube cradle frame. Forks are standard telescopics (without gaiters); and rear suspension is via twin shocks(5 step adjustable). The
ABS brakes comprise single discs: 320mm (front) and 240mm (rear). Instruments are conventional twin-dial analogue items with digital fuel gauge and trip display. In 2022, it starts at an ex-showroom price of in India.
Bear 650 The Royal Enfield Interceptor Bear 650 was officially released on October 31, 2024. It has been described as "a stylish scrambler-styled standard based primarily on the brand’s INT 650 model, though with some notable differences." On the Design and Styling front, Bear 650 comes with a scrambler seat, side panel number boards, and urban-off-road aesthetics. Full LED lights bring modern functionality. Derived from the Shotgun series this motorcycle uses Showa USD Forks, but optimized for scrambler duties with longer suspension travel. To complement its off-road credentials, the ride height has been raised. The Interceptor Bear 650 retains the Interceptor 650's brakes but upgrades the front disc size for added stopping power along with Dual-channel ABS with a switchable rear ABS. Equipped with a full-color TFT screen with integrated navigation brings modern tech to the classic platform. Powered by the 650cc parallel-twin engine delivering 46.80 bhp and an increased torque of 57N-m (5N-m more than the Interceptor), while saving weight owing to two-into-one exhaust system. ==Reception==
