The Aprilia RS 660 has always been a favourite among enthusiasts who want serious performance without committing to a litre-class superbike. With the 2025 update, the RS 660 finds itself in the spotlight once again — and this time, it’s selling out faster than ever. Riders looking for a middleweight sports bike that combines power, premium features, and everyday usability are flocking to showrooms, especially with limited units currently available. The bike’s Italian design, modern electronics, and an engaging 660 cc engine continue to make it one of the most desirable machines in its segment.

Aprilia RS 660 – The Middleweight That Stands Apart

Aprilia RS 660’s Stylish Design with a Purpose
The RS 660 showcases Aprilia’s racing DNA through:
Aerodynamic bodywork
Inspired by the brand’s larger superbikes, the fairing incorporates subtle winglets that improve stability at higher speeds.
Compact yet muscular stance
The slim tank design allows riders to grip comfortably, and the aggressive front fascia gives it an unmistakable Italian identity.
Premium build quality
Fit and finish is among the best in the segment — from the sculpted panels to the detailed LED lighting setup.
Aprilia has managed to create a motorcycle that’s as visually appealing as it is functional. Whether standing still or cruising through the city, the RS 660 never fails to draw attention.
Feature-Loaded to the Core
One of the biggest highlights of the RS 660 is its advanced electronics — something usually seen on bigger and more expensive superbikes.
6-axis IMU
This is the heart of the bike’s safety and control system, enabling:
- Traction control
- Wheelie control
- Engine-brake management
- Cornering ABS
- Multiple ride modes (Road, Track, and Custom)
Full LED lighting
Bright and modern, improving visibility during night rides.
TFT Digital Cluster
Displays ride data clearly — speed, modes, fuel, temperature, and more.
Lightweight chassis
Helps the bike remain agile in corners and stable at high speeds.
All these features make the RS 660 one of the most technologically advanced bikes in its class.
Aprilia RS 660 Engine and Performance: Built for Pure Riding Pleasure
Aprilia’s 659 cc twin-cylinder engine is tuned for both performance and practicality.
Power Delivery
The bike makes around 100 PS, which is more than enough for spirited highway runs and track sessions. The torque kicks in early, making city rides smooth and enjoyable.
Acceleration & Speed
- 0–100 km/h in under 4 seconds
- Top speed close to 230 km/h
Gearbox
The 6-speed transmission with slipper and assist clutch offers crisp shifts and better control during hard braking.
Real-World Riding
While the RS 660 is undeniably sporty, it is surprisingly comfortable for city commutes — thanks to its upright-ish ergonomics and manageable seat height. Unlike full supersport bikes that strain the wrists, the RS 660 keeps things relaxed enough for daily use.
Why the Aprilia RS 660 Is Selling Out So Fast
The reference article highlights several reasons for the current surge in demand:
1. Limited units available
With the RS 660 being an imported model, supply is always small. When stock arrives, buyers often rush to secure a unit.
2. Premium features at a fair price
Considering the electronics package and build quality, the pricing is competitive compared to European competitors.
3. Rising interest in middleweight sports bikes
More riders are shifting towards the 600–700 cc category for a more practical yet exciting riding experience.
4. Strong word-of-mouth reputation
The RS 660’s reliability, comfort, and sporty nature have created a loyal fan base.
Riding Experience: On Road and Track
The RS 660 shines in nearly all environments:
City Riding
- Smooth power delivery
- Light clutch
- Comfortable seat
- Easy maneuvering due to light weight
Highways
- Strong mid-range for effortless overtaking
- Stable at high speeds
- Wind protection thanks to the fairing
Track
- Sharp cornering ability
- Adjustable suspension
- Strong brakes with cornering ABS
This versatility makes the RS 660 one of the most rider-friendly performance bikes available.
Comparison: How RS 660 Holds Up Against Rivals
