The bike is equipped with advanced features like ABS and adjustable suspension, which contribute to its overall performance and handling on the track.
Maximum Speed of 179 Km/H
Maximizing engine efficiency is key to reaching the KTM RC 390's impressive top speed of 179 km/h (112.5 mph). Powered by a 373 cc engine that delivers 43.5 PS at 9000 rpm, this lightweight machine thrives in its optimal RPM range, which is between 7000 and 10000 rpm. This power, combined with a high compression ratio of 12.88:1, allows you to experience exhilarating acceleration and responsiveness. To achieve peak performance, you should shift gears around 10,000 rpm. This ensures you're always harnessing the engine's full potential, propelling you from 0 to 60 mph in just 4.24 seconds. The Ninja 400's higher peak power and torque figures further illustrate the competitive landscape in this class. The RC 390's liquid-cooled system also helps maintain optimal temperatures, allowing for sustained high-speed runs without overheating. The bike's lightweight design—wet weight of only 172 kg—enhances its handling and agility. With its split-trellis frame and advanced WP suspension, you'll enjoy tremendous stability at high speeds. By understanding the gear and speed relationships, you can maximize your riding experience, cruising comfortably at 60-70 mph while still leaving room for more power when needed.
Throttle Response Improvement
Improving throttle response is essential for enhancing your riding experience on the KTM RC 390. You'll notice the benefits immediately with quicker throttle response through optimized maps, especially in closed-loop and part-throttle regions. The advanced ignition control algorithms ensure strong, smooth power delivery while minimizing engine vibrations, making your rides more enjoyable. To take your throttle response to the next level, consider mechanical modifications like a quick action throttle mod that reduces throttle travel by up to 20%. Installing a throttle body spacer can also improve airflow, enhancing your bike's responsiveness. Adjusting the throttle cam allows you to reach wide-open throttle with less rotation, making acceleration feel more immediate. Routine maintenance plays a crucial role too. Replacing worn-out spark plugs, changing dirty air filters, and cleaning clogged fuel injectors can significantly boost engine efficiency and throttle response. Additionally, lubricating throttle cables will ensure a smoother operation. For a performance edge, consider a cold air intake and a well-designed exhaust system, which together enhance airflow and power. Additionally, the PowerTRONIC V4 provides an option for improved throttle response through adjustable fuel and ignition mapping. These upgrades not only improve responsiveness but also elevate your overall riding experience on the KTM RC 390.
Aerodynamic Bodywork Design
The KTM RC 390 boasts aerodynamic bodywork designed to enhance engine efficiency and overall performance. Inspired by Grand Prix styling and optimized through computational fluid dynamics, the bike features race-inspired lines that not only look stunning but also improve aerodynamics. This design directs airflow away from you, providing enhanced wind and weather protection.
You'll appreciate how the inner and outer body panels channel airflow effectively, resulting in improved heat management around your riding position. The reduced rear bodywork gives the RC 390 a more aggressive profile while exposing the redesigned steel trellis subframe, allowing for cooler engine operation. Additionally, the bike's lightweight trellis frame contributes to overall handling and maneuverability, making it an ideal choice for spirited riding.
Rider comfort is also a priority with ergonomic enhancements. The knee area is crafted for fluid movement, while a narrower profile increases contact area for better control. The all-new two-part cockpit and windscreen holder further refine your experience.
With a lightweight design, the new frame is 1.5 kg lighter than its predecessor, and the redesigned wheel saves 3.4 kg in unsprung weight. This efficient bodywork, combined with practical features like easily removable panels, maximizes your ride on the track or the streets.
Rider Comfort on Long Rides
When it comes to long rides on the KTM RC 390, rider comfort can be a significant concern. The aggressive riding position, characterized by low clip-ons and high footpegs, is great for sporty performance but can leave you feeling uncomfortable after just an hour. You might find your back and quads losing sensation, making you crave relief.
While the handlebars are positioned closer, allowing for a slightly more upright posture, it isn't enough for those prioritizing comfort. The standard seat isn't designed for long distances either. If you're planning extended rides, consider the optional Ergo seat, which features foam and gel construction for better pressure distribution and legroom. This could make a noticeable difference, especially on broken roads. Additionally, the RC 390's aggressive riding position enhances enjoyment during spirited rides but can compromise comfort on longer journeys.
Regarding suspension, the revised setup helps with rough surfaces but isn't plush. High-amplitude bumps might still lead to discomfort in your arms, wrists, or lower back.
Although it handles well on smooth roads, the RC 390 isn't ideal for long tours on rough terrain. Keep in mind that rider stature and arm length can also affect comfort levels during those lengthy adventures.
