1350cc V-Twin Engine and Acceleration
The KTM 1390 Super Duke R is powered by a massive 1,350cc, 75-degree V-twin engine built for strong acceleration and instant throttle response. With 187.7 hp and 106.9 lb-ft of torque, it delivers powerful performance across the rev range. Its six-speed gearbox, slipper clutch and advanced electronic rider aids help manage the engine's considerable power. Unlike traditional superbikes, the Super Duke R combines extreme performance with an upright naked-bike riding position.
Real-World MPG and Highway Riding
Fuel economy is not the main reason riders choose the Super Duke R. Independent road testing has reported approximately 48 UK mpg, equivalent to around 40 US mpg, although aggressive riding can reduce fuel efficiency. Its 4.62-gallon fuel tank provides useful range for weekend rides and longer trips. The upright riding position offers good control, but its naked-bike design provides less wind protection than a fully faired superbike at highway speeds.
Features, Technology and Final Verdict
The KTM 1390 Super Duke R features cornering traction control, multiple riding modes, cornering ABS, cruise control and a modern TFT instrument display. Its Brembo Stylema braking system and fully adjustable WP APEX suspension provide the hardware needed to handle its impressive performance. The 1390 Super Duke R is a strong choice for riders who want superbike-level power in a naked motorcycle. Its main attractions are the enormous V-twin engine, aggressive styling and exciting road performance, although its fuel consumption and limited wind protection are worth considering before buying.
