The 2017 RC 390 stands as a pivotal model in the entry-level performance motorcycle segment, marking a significant evolution for its manufacturer. Introduced as the successor to the 2016 model, this bike was developed with a clear directive: to refine the dynamic handling and rider-focused experience that defined its predecessor while addressing earlier mechanical nuances. Positioned as a track-day weapon disguised as a street bike, the 2017 RC 390 achieved a delicate balance between accessibility for new riders and the raw engagement sought by seasoned enthusiasts.
Design Philosophy and Visual Identity
From the outset, the 2017 RC 390 signaled its intent through a sharp design language that departed from the more conservative aesthetics of budget motorcycles. The angular fairings and aggressive stance were not merely for visual appeal; they were engineered to optimize high-speed stability and reduce wind buffeting at the rider. The integration of the headlight into the upper fairing created a signature "eyebrow" look, enhancing brand recognition while maintaining a functional profile. This cohesive design language extended to the slimmer side panels, which contributed to a reduced frontal profile and improved maneuverability in tight urban environments.
Chassis, Suspension, and Handling Dynamics
Handling remains the 2017 RC 390's most celebrated attribute, achieved through a meticulously calibrated chassis setup. The inclusion of an upside-down fork at the front was a significant upgrade, offering superior control and a more direct connection to the road surface compared to conventional telescopic forks. This configuration, paired with a lightweight diamond frame, resulted in exceptionally nimble steering and confident cornering geometry. The rear suspension, featuring a monoshock absorber, was tuned to manage the bike's lightweight chassis effectively, providing stability without sacrificing the sharp feedback that defines its riding dynamics.
Performance Specifications and Engine Character
Under the seat, the 2017 RC 390 houses a single-cylinder, liquid-cooled engine that dispels any doubts about its classification as a mere commuter bike. With a displacement of 373cc, this powerplant delivers a torquey mid-range perfect for urban weaving and spirited back-road runs. The output is tuned for controlled aggression, producing a peak that is both thrilling and manageable. The engine's compact layout contributes to a near-perfect weight distribution, enhancing the bike's agility. The exhaust note, a sharp and eager bark, further reinforces its performance credentials, transforming every ride into an engaging experience that prioritizes rider involvement over passive comfort.
Braking and Safety Features
Safety and control are paramount in a performance-oriented machine, and the 2017 RC 390 addresses this with a robust braking system. The front is equipped with a single, floating disc brake clamped by twin-piston calipers, delivering powerful and linear stopping power essential for dynamic riding. The rear features a single-piston caliper acting on a smaller disc, ensuring balanced brake force distribution. For the 2017 model year, manufacturers placed increased emphasis on reliability, incorporating features like adjustable brake levers and high-quality sintered pads to maintain consistent performance across varied riding conditions and temperatures.
ergonomics and Rider Position
The rider ergonomics of the 2017 RC 390 are designed to promote an aggressive yet sustainable posture. The relatively low seat height ensures that riders of various statures can confidently place both feet on the ground, a crucial factor for confidence in stop-start traffic. The narrow fuel tank profile allows for knee placement, enhancing security in corners. While the clip-on handlebars and rear-set footpegs deliver a sporty positioning, the overall setup is less extreme than dedicated race replicas, making it feasible for longer rides without excessive strain on the wrists and back.
