CFMOTO NK 650 [2021-2022] Review: A Modern Middleweight With Surprises Up Its Sleeve
Introduction
The CFMOTO NK 650 represents a bold statement in the middleweight naked bike segment. Produced from 2021 to 2022, this Chinese-made twin-cylinder machine challenges preconceptions about value-oriented motorcycles. With its aggressive styling, approachable ergonomics, and peppy performance, the NK 650 aims to lure riders away from established Japanese and European rivals. But does it succeed? Let’s dissect this intriguing package through the lens of real-world usability.
Design & First Impressions
At first glance, the NK 650 doesn’t scream “budget bike.” The angular LED headlight cluster, sculpted 17-liter fuel tank, and sharp tail section give it a contemporary, almost European flair. The two-tone color schemes—Nebula White with black accents or Athens Blue with silver highlights—add visual depth rarely seen in this price bracket.
The 780mm seat height (30.7 inches) accommodates shorter riders comfortably while still offering enough room for taller pilots to stretch out. CFMOTO’s designers clearly prioritized ergonomic neutrality—the slightly rear-set footpegs and flat handlebars create a natural riding triangle suitable for both city commuting and weekend blasts.
Build quality surprises with consistent panel gaps and decent material choices. While not quite at Yamaha MT-07 levels of finish, the NK 650’s 206kg (454 lbs) curb weight feels well distributed when pushing it off the stand. The LCD instrument cluster—though basic compared to TFT displays—provides crisp readouts for speed, RPM, gear position, and fuel level.
Performance: Twin-Cylinder Punch
The beating heart is a liquid-cooled 649cc parallel twin derived from Kawasaki’s ER-6 platform. Updated with CFMOTO’s DOHC cylinder head and EFI mapping, it churns out 60.4 HP @ 8,750 RPM and 56 Nm (41.3 lb-ft) @ 7,000 RPM. These numbers slot neatly between the Kawasaki Z650 (67 HP) and Honda CB500F (47 HP).
Twist the throttle, and the engine responds with linear urgency. Below 5,000 RPM, torque delivery feels civilized—perfect for urban crawling. Past 6,000 RPM, the character transforms as the DOHC valvetrain lets the twin breathe freely, pulling hard to its 10,000 RPM redline. The 6-speed gearbox shifts with positive clicks, though the clutch requires firm lever action in stop-and-go traffic.
Top speed sits at a governed 180 km/h (112 mph), though the NK feels most alive between 90-140 km/h (56-87 mph). Fuel consumption averages 4.2 L/100km (56 mpg) during mixed riding, giving a theoretical range of 400km (248 miles) from its 17L tank.
Handling & Suspension
KYB suspenders front and rear give the NK 650 an edge over price-equivalent competitors. The 41mm USD forks offer 120mm (4.7") of travel, tuned for supple bump absorption without wallowing mid-corner. Out back, the KYB monoshock provides 45mm (1.8") of wheel travel—adequate for solo riders, though two-up touring reveals some limitations.
With a 1,450mm (57.1") wheelbase and 150mm (5.9") ground clearance, the NK carves corners with unexpected agility. The 120/70-17 front and 160/60-17 Michelin Pilot Street tires (standard on EU models) provide ample grip for spirited riding. Braking comes via dual 300mm front discs with J.Juan 4-piston calipers—a noticeable step up from budget single-disc setups. Stops from 100 km/h (62 mph) feel confident, though ABS would’ve been welcome.
Technology & Features
While not overflowing with gadgets, the NK 650 includes thoughtful touches:
- Full LED lighting (headlight, taillight, turn signals)
- Slip/assist clutch for smoother downshifts
- Dual-channel ABS (post-2021 models in select markets)
- USB charging port under the seat
The EFI system deserves praise—cold starts are drama-free even at 5°C (41°F), and throttle response stays crisp across temperature ranges. Riders accustomed to carbureted bikes will appreciate the lack of choke fiddling.
Competition
The NK 650’s closest rivals include:
1. Kawasaki Z650
- Pros: Lighter (187kg), stronger mid-range, superior dealer network
- Cons: Higher price, basic suspension, dated styling
2. Honda CB650R
- Pros: Iconic inline-4 sound, premium build, Showa SFF-BP forks
- Cons: Heavier (202kg), pricier, higher seat (810mm)
3. Yamaha MT-07
- Pros: Legendary CP2 engine, 68 HP, cult following
- Cons: Firmer seat, no LED lights pre-2021, premium pricing
Where the NK 650 Shines:
- Best value per horsepower
- Superior stock suspension (KYB > basic Showa/Kayaba units)
- Modern LED lighting as standard
