The Honda NC 750 X (RH09) represents the pinnacle of ‘New Concept’ engineering. A unique historical highlight of this platform is its genetic link to the automotive world; the original NC engine architecture was derived from the Honda Jazz (Fit) 1.3L automotive engine, halved to create a high-torque, ultra-efficient motorcycle powerplant with a low center of gravity that remains unmatched in the crossover segment.
Technical Engineering Analysis
The RH09 generation, introduced for the Euro 5 era, saw a significant weight reduction of 6kg over its predecessor and a revised intake system that increased power to 43.1kW. The Dual Clutch Transmission (DCT) version remains the industry benchmark, utilizing two clutches for seamless gear changes without power interruption. For the RH09, Honda shortened the ratios for gears 1, 2, and 3 to improve acceleration, while maintaining tall 4th, 5th, and 6th gears for fuel economy.
Maintenance Essentials
Proper lubrication is critical for the longevity of the NC 750 X, especially the DCT variant which relies on oil pressure for clutch actuation. MotoSpecsLab recommends strictly adhering to the SAE 10W-30 API SG or higher specification. Note that the total oil capacity is 3.4 Liters during a standard filter change.
Ignition and Electrical
The RH09 utilizes high-performance NGK IFR6G-11K iridium spark plugs. These are designed for long service intervals but should be inspected for fouling if the bike is used primarily for short city commutes. The electrical system is supported by the YTZ12S battery, which must be kept at a full charge to ensure the DCT solenoids function correctly during startup.
Chassis and Safety
The handling characteristics of the NC 750 X are highly sensitive to tire pressure. To maintain the intended geometry and fuel efficiency, the 17-inch radial tires must be kept at 2.5 bar (Front) and 2.9 bar (Rear). These pressures are optimized for both solo riding and carrying luggage in the 23L integrated ‘frunk’.
Expert Verdict
As a technical platform, the RH09 is a masterclass in pragmatic engineering. It prioritizes usable torque and efficiency over high-RPM performance. For the owner, it offers one of the lowest total costs of ownership in the mid-capacity class, provided the specific DCT maintenance and fluid requirements are met.
