The Yamaha R9 and the Aprilia RS 660 are two of the most exciting middleweight sportbikes in 2024. Both bikes blend high-performance engineering with advanced technology, making them favorites for riders who want a mix of track capability and street usability. But which one is the better choice? Let’s compare their performance, features, and value to determine the winner of this epic showdown.
Engine & Performance: Inline-Triple vs. Parallel-Twin
One of the biggest differences between these two bikes is their engine configuration and power output.
Yamaha R9
- Engine: 889cc inline-three (CP3)
- Horsepower: ~119 HP @ 10,000 RPM (Expected)
- Torque: ~93 Nm @ 7,000 RPM (Expected)
- Top Speed: ~160 mph (Expected)
- Transmission: 6-speed with quickshifter
Aprilia RS 660
- Engine: 659cc parallel-twin
- Horsepower: ~100 HP @ 10,500 RPM
- Torque: ~67 Nm @ 8,500 RPM
- Top Speed: ~150 mph
- Transmission: 6-speed with quickshifter
Verdict: The Yamaha R9 has a clear advantage in power and torque, thanks to its larger CP3 inline-three engine. The RS 660, however, is lighter and has a high-revving nature, making it an agile competitor.
Riding Experience: Track vs. Street
Both bikes offer an engaging ride, but they cater to slightly different rider preferences.
Yamaha R9 – Aggressive Track Dominator
More power for high-speed straights Quickshifter and traction control for seamless shifting Smoother torque delivery for mid-corner acceleration Brembo brakes for superior stopping power
Aprilia RS 660 – Precision and Handling
Lighter chassis for better cornering Sophisticated electronics package (IMU-based ABS, multiple riding modes) More compact and nimble in tight sections Better fuel efficiency for everyday riding
Verdict: The R9 is better suited for aggressive riders who love straight-line speed, while the RS 660 excels in handling and rider-friendly features.
Price & Value for Money
Cost is a big factor for many riders, and here’s how the two bikes compare:
- Yamaha R9 Expected Price: $11,500 – $13,000
- Aprilia RS 660 Price: $11,499 (Base Model)
Verdict: The pricing is quite similar, but the RS 660 offers a high-tech electronics package, while the Yamaha R9 provides more raw power and performance.
