The return of affordable inline-four sportbikes has created plenty of excitement among motorcycle enthusiasts. Two of the latest models to enter this growing segment are the ZXMOTO 500RR and the CFMOTO 500SR VOOM.
Both motorcycles are powered by high-revving four-cylinder engines that deliver an exhilarating riding experience once reserved for larger supersport machines. They also feature aggressive styling, modern electronics, and premium chassis components, making them attractive options for riders looking to step into the middleweight sportbike category.
Although they share similar engine configurations, the two motorcycles offer different personalities. The ZXMoto 500RR focuses on outright supersport performance, while the CFMOTO 500SR VOOM blends neo-retro styling with modern technology and everyday usability.

Engine and Performance
ZXMoto 500RR
The 500RR is powered by a 470cc liquid-cooled DOHC inline-four engine producing 84 hp and 46 Nm of torque. The engine revs all the way to 13,500 rpm and can go up to 235 km/h delivering the high-pitched exhaust note and thrilling top-end performance that many sportbike enthusiasts have been waiting for. It is paired with a six-speed gearbox featuring a quickshifter and wet multi-plate slipper clutch.
CFMOTO 500SR VOOM
The 500SR VOOM features a slightly larger 499cc liquid-cooled DOHC inline-four engine producing around 78 hp (up to 82 hp with ram air) and 49 Nm of torque with a claimed top speed of around 220 km/h. It uses a six-speed transmission with an assist and slipper clutch and quickshifter. Thanks to its Ram Air system, the engine delivers impressive acceleration while maintaining smooth power delivery across the rev range.
On paper, the ZXMoto enjoys a slight horsepower advantage, while the CFMOTO produces more torque. Riders looking for an exciting, high-revving supersport feel may prefer the 500RR, whereas those seeking stronger mid-range performance for both city and highway riding may go for the 500SR VOOM.

Features and Technology
ZXMoto 500RR
The 500RR comes equipped with a full-colour TFT display, ride-by-wire throttle, multiple riding modes, cruise control, cornering ABS, switchable traction control system (TCS), and launch control supported by a six-axis IMU, up-shift quickshifter, fully adjustable suspension, and a premium single-sided aluminium swingarm. These features give it a very competitive specification for its class.
CFMOTO 500SR VOOM
Meanwhile, the 500SR VOOM offers an equally impressive list of technology. Riders get a curved 5-inch TFT display, up-shift quickshifter, steering damper, dual-channel ABS, two-mode traction control system (TCS), Emergency Stop Signal (ESS), USB-A and USB-C charging ports, and smartphone connectivity.
Both motorcycles provide premium technology, but they have different priorities. The ZXMoto focuses more on track-oriented performance, while the CFMOTO offers a wider range of rider-assistance features for everyday usability.

Ergonomics and Comfort
ZXMoto 500RR
The 500RR features an 800 mm seat height and weighs approximately 168 kg, making it significantly lighter than its rival. Its aggressive riding position, clip-on handlebars, and lightweight chassis make it feel nimble during spirited riding and track sessions.
CFMOTO 500SR VOOM
The 500SR VOOM has a slightly lower 795 mm seat height but is slightly heavier, around 194 kg. However, it compensates with optional seat height choices, adjustable suspension, and ergonomics that are slightly less aggressive, making it more comfortable for longer rides.
If agility and lightweight handling are your priorities, the ZXMoto has the edge. Riders looking for a more versatile sportbike that remains comfortable during daily use may lean towards the CFMOTO.
