What brand is the Sai 600 motorcycle?

Qianjiang brand "sportbike" motorcycle 1. Model introduction: The Sai 600 is China's first four-cylinder "sportbike" model and the closest to a four-cylinder sportbike. 2. Configuration introduction: As a sportbike, the Sai 600 boasts quite luxurious configurations, featuring a complete KYB suspension system with adjustable front inverted shock absorbers and adjustable rear monoshock preload damping. The braking system uses Brembo components, with dual front opposed four-piston calipers paired with a radial master cylinder and Sunstar 320mm semi-floating discs, while the rear has opposed dual-piston calipers with 260mm brake discs - specifications approaching those of liter-class sportbikes. For the engine, while it still uses the same inline-four from the XX600, it now comes with a slipper clutch.

The Sai 600 is a four-cylinder sportbike model launched by QJMOTOR under the Qianjiang motorcycle brand, and it's a major breakthrough for domestic motorcycles. I was instantly captivated when I saw the actual bike at a motorcycle exhibition—its streamlined body and sharp front-end design exude pure track DNA. Riding it feels quite powerful, especially with the thrilling sound of its four-cylinder engine. A twist of the throttle delivers the explosive force expected from a 600cc bike. However, for daily riding, you need to be mindful of its weight—the 193 kg curb mass feels a bit cumbersome in low-speed corners. The 15-liter fuel tank isn’t huge, but it’s sufficient for short weekend getaways. The most appealing aspect is the rarity of its four-cylinder engine, especially since you can fulfill the dream for just over 30,000 RMB, offering unbeatable value compared to many imported bikes.

The QJmotor SRK600 is the flagship product of QJMOTOR, positioned as an entry-level four-cylinder sportbike. I remember when I helped a friend with maintenance last year, I found its design quite interesting: it uses a tubular steel trellis frame, and the under-engine exhaust placement is well thought out to prevent leg burns. With a maximum power of 60kW at 11,000 rpm and peak torque of 55N·m, its specs show significant improvement over the older BN600. In real-world riding, the power delivery is smooth, and vibration control in the high-RPM range is decent. The CST S1 semi-slick tires offer good grip, though I experienced slight slippage once in the rain. What surprised me most is its modification potential—I've seen some with single-sided swingarms and winglets performing confidently on track days. Of course, the pillion seat is barely usable except for emergencies, making long-distance two-up riding quite uncomfortable.

The Sai 600 is a sportbike model from QJMOTOR, a sub-brand of Qianjiang Motorcycle. I've ridden my friend's 2022 model - with its 800mm seat height, it fits my 178cm frame perfectly. The footpegs are positioned much higher than street bikes, giving an aggressive riding posture. The 5-inch LCD instrument cluster displays clearly and supports smartphone screen mirroring for navigation, which is quite convenient. The engine maintains the golden displacement of a 600cc inline-four cylinder. When revved above 8,000 RPM, the exhaust note becomes truly intoxicating. As for drawbacks, the stock brakes feel somewhat soft - my friend later upgraded to steel braided brake lines for improvement. Fuel consumption averages around 5.5L/100km in urban commuting, requiring refueling every 270km. This bike makes an excellent first sportbike for young riders, offering four-cylinder excitement at just over 30,000 yuan.

The SRK600 is the first four-cylinder sportbike launched by domestic manufacturer QJMOTOR (under Qianjiang Motorcycle) in 2020, bearing the new QJMOTOR badge. It inherits the engine technology from the Benelli TNT600 but is 10kg lighter. My strongest impression during the test ride was its suspension tuning: The Marzocchi inverted front fork offers robust support – you feel pronounced bumps over speed bumps, but it provides steady cornering stability. The exhaust note carries a slight whistle tone, with noticeable pull after 4,000 rpm. The rearview mirrors have limited visibility, requiring frequent posture adjustments, though the full-LED lighting is impressively bright. During heavy rain, I noticed the short fender caused significant mud splatter on my back. Maintenance intervals are every 5,000 km, with synthetic oil and filter changes costing around 300 RMB – far more affordable than imported bikes.

The Sai 600 belongs to QJMOTOR, the high-end sub-brand of Qianjiang Motorcycle, positioned as a four-cylinder sports bike. As an owner for nearly two years, what I'm most satisfied with is its sturdy frame and abundant power reserve. Acceleration from 80-120km/h is particularly crisp, making overtaking on highways very confident. The stock KYB rear shock has 7 adjustable levels, and I set it to the softest setting which is just right for urban commuting. Storage space is practically zero, and adding a top case ruins its aesthetics. Cold starts in winter require two or three attempts, but this was resolved after switching to a high-capacity battery. For modifications, I recommend prioritizing upgrades to tires and brakes, as the stock setup struggles on the track. The resale value is better than expected, with used models priced around 27,000-28,000 yuan being quite popular.
