For the "Ready to Race" enthusiast, the KTM RC 390 is more than just a small-displacement motorcycle—it is a scalpel. It is a machine that rewards high corner speeds, late braking, and aggressive body positioning. Whether you are competing in a 300cc cup series or terrorizing local canyon roads, your gear must be as precise as the bike’s trellis frame.
A generic, off-the-shelf suit might provide basic protection, but a is a technical necessity for those looking to unlock the bike's full potential. Here is a deep dive into why specialized, custom-made leather is the ultimate performance upgrade for your RC 390.
1. Ergonomics Built for the Supersport Tuck
The RC 390 features an aggressive, forward-leaning geometry. Unlike a standard naked bike, the clip-ons are low and the rear-sets are high, forcing the rider into a compact "ball" to minimize aerodynamic drag.
A dedicated RC 390 suit is engineered with pre-curved limbs. By tailoring the leather to naturally curve at the elbows and knees, we eliminate the "resistance" that occurs when moving from a neutral stance to a full racing tuck. This means your muscles work less to hold a position, reducing rider fatigue during long track sessions.
2. The Science of the "Second Skin" Fit
At Motospeeds, we don't believe in "Small, Medium, or Large." For a bike as nimble as the RC 390, any excess leather creates "buffeting"—a vibrating effect caused by wind catching loose material at high speeds. This vibration isn't just annoying; it disrupts your focus and adds aerodynamic drag to a bike that only has 44 horsepower to spare.
Our 26-measurement precision system ensures that the suit adheres perfectly to your unique anatomy. By mapping everything from your forearm circumference to your torso length, we ensure the armor stays exactly where it’s meant to be, even during a high-speed slide.
3. Material Integrity: Protection Without the Bulk
While the RC 390 is lightweight, the forces involved in a crash remain significant. Our suits utilize a hybrid construction of Premium 1.3mm Cowhide and Kangaroo Leather.
-
Cowhide: Used in primary slide zones like the hips and seat for maximum abrasion resistance.
-
Kangaroo Inserts: Integrated into the palms and inner arms. Kangaroo leather is thinner and more flexible than cowhide while maintaining higher tensile strength, providing the rider with a better "feel" for the RC 390’s sensitive throttle and brake inputs.
-
Aramid Stretch Panels: Strategically placed in the crotch and underarms to allow for the wide-leg "knee-down" transitions that the RC 390 excels at.
4. Technical Hardware for the Track
A suit for the RC 390 isn't just about leather; it’s about the hardware integrated into it.
CE-Level 2 Armor:
We integrate ultra-thin, high-absorption protectors at the shoulders, elbows, and knees. On a small bike like the RC 390, bulky armor can interfere with your ability to tuck your elbows into the tank recesses. Our CE-Level 2 armor provides maximum protection with a low-profile footprint.
External TPU Friction Shields:
The "Orange" aesthetic is often complemented by high-density TPU (Thermoplastic Polyurethane) sliders on the shoulders and elbows. These serve as a sacrificial layer; instead of the leather catching the asphalt and causing a tumble, the TPU allows you to slide smoothly, significantly reducing the risk of rotational injuries.
5. Thermal Regulation for the "Orange" Heat
Small-displacement racing is physically demanding. You are constantly shifting your weight and working the gears. This generates immense body heat. Our KTM RC 390 suits feature targeted laser perforation.
By micro-perforating the chest and thigh panels, we allow a constant stream of air to wick away sweat and cool your core. Crucially, we keep the impact-prone seams solid to ensure the suit’s structural integrity is never compromised.
6. Bespoke Design: Representing the Brand
Riding a KTM is a statement. Your gear should reflect the "Ready to Race" heritage. Our bespoke design service allows you to customize the aesthetic to match the factory KTM livery:
-
Black and Electric Orange color.
-
Integrated Branding: We can embroider or print sponsor logos directly into the leather panels during construction.
-
Aero-Hump Customization: Choose a ventilated or hydration-ready hump to suit your racing environment.
Conclusion: Confidence is Speed
The KTM RC 390 is a precision instrument. To play it well, you cannot be fighting your gear. A provides the confidence to lean further, brake later, and trust in your equipment. It is the bridge between the rider and the machine.
When you zip up a Motospeeds suit, you aren't just putting on leather—you are putting on a piece of engineering tailored specifically for you and your RC 390.
