1. Engine & Performance: Three Mechanical Philosophies
Aprilia RS 660 (659 cc Parallel-Twin – 105 HP): The undisputed performance king. The Euro 5+ update featuring 52 mm throttle bodies delivers a stout mid-range and a fierce top-end pull all the way to a true 240 km/h (149 mph).
Triumph Daytona 660 (660 cc Inline-Triple – 95 HP): The triple offers the sweetest spot: twin-like low-end torque combined with a silky, linear rev-out up to 11,250 RPM.
Yamaha R7 (689 cc CP2 Parallel-Twin – 73.4 HP): Lower horsepower on paper, but the famous CP2 engine serves up instant down-low grunt, making it punchy and immensely fun in tight twisties.
2. Riding Position & Ergonomics: Street vs. Track
Yamaha R7 (Pure & Radical): Clip-ons mounted beneath the top triple clamp and raised rearsets. The stance is 100% racing—fantastic for track days, but punishing on the wrists in city traffic.
Aprilia RS 660 (Balanced Sport): Clip-ons positioned above the top triple clamp. It gives you front-end feedback during aggressive riding without wrecking your wrists and back on daily commutes.
Triumph Daytona 660 (Sport-Touring): The most comfortable of the trio. Relaxed ergonomic geometry makes it the ideal pick for weekend long-distance rides and daily riding.
3. Electronics & Chassis
Aprilia RS 660: Dominates technically. Features a 6-axis IMU, Cornering ABS, Traction Control, Wheelie Control, Riding Modes, and a standard bi-directional Quickshifter (plus Öhlins suspension on the Factory variant).
Triumph Daytona 660: Modern yet essential. Equipped with Ride-by-Wire, 3 Riding Modes (Sport, Road, Rain), switchable Traction Control, and standard ABS.
Yamaha R7: Pure analog approach: no traction control or engine maps, just standard ABS and a sharp, well-sorted stock chassis.
4. Running & Maintenance Costs
Yamaha R7: Lowest ownership costs in the category. The ultra-proven CP2 engine is rock-solid, frugal on gas (over 22 km/L / 51.7 mpg), and cheap to service.
Triumph Daytona 660: Generous service intervals (16,000 km / 10,000 miles), which significantly lowers long-term ownership costs.
Aprilia RS 660: The most sophisticated machine requires attentive maintenance, especially in the Öhlins-equipped Factory trim. Average fuel consumption sits around 18 km/L (42.3 mpg).
The Verdict: Which Should You Buy?
Choose the Aprilia RS 660 if: You want top-tier performance, advanced technology, and cornering mastery. For outright track efficiency, the Factory version stands unrivaled.
Choose the Yamaha R7 if: You want the ergonomics and feel of a "true Superbike" paired with low running costs and a raw, electronic-free riding style.
Choose the Triumph Daytona 660 if: You need versatility. The triple-cylinder engine shines on the street, and its price-to-power ratio (95 HP under €10,000) is unbeatable.
