How the Aprilia RS 660 Redefined Middleweight Motorcycles

February 20, 2025

The world of motorcycles has always been a battle of extremes—lightweight beginner bikes on one end and fire-breathing liter-class machines on the other. But in recent years, the middleweight segment has surged in popularity. Riders are looking for the perfect balance between power, agility, and practicality, and manufacturers are racing to fill the gap.

Enter the Aprilia RS 660, a bike that didn’t just enter the middleweight class—it redefined it. By blending superbike DNA with real-world usability, the RS 660 has set a new benchmark for what a middleweight sportbike should be.

The Vision Behind the Aprilia RS 660

Aprilia, a brand with deep racing heritage, saw an opportunity in the market. Riders wanted a bike that had the exhilaration of a supersport but without the extreme weight, discomfort, and cost of a full-blown superbike.

How Aprilia's APRC Technology Revolutionized Rider Safety

The RS 660 was designed to bridge the gap between entry-level bikes and high-performance liter-class monsters. With its advanced engineering, cutting-edge electronics, and lightweight chassis, the RS 660 makes high-performance riding more accessible and enjoyable for a broader range of riders.

Innovative Engineering and Lightweight Design

Chassis & Weight:

One of the key ways Aprilia redefined the middleweight segment was by focusing on lightweight performance. The RS 660 features an aluminum twin-spar frame that contributes to a class-leading dry weight of just 169 kg (372 lbs). This makes it incredibly nimble, whether carving through canyons or attacking the track.

Engine Performance:

At the heart of the RS 660 is a 659cc parallel-twin engine, derived from Aprilia’s legendary RSV4 superbike. It delivers 100 horsepower, an impressive number for a middleweight. The engine offers a smooth powerband, making it accessible for new riders while still delivering thrilling top-end performance for experienced motorcyclists.

Power-to-Weight Ratio Advantage:

The RS 660’s lightweight design gives it a power-to-weight ratio that challenges even some larger sportbikes, allowing it to accelerate quickly and handle effortlessly.

Advanced Electronics: Raising the Bar

One of the most groundbreaking aspects of the RS 660 is its advanced electronic suite, which is rare in the middleweight category.

Aprilia Performance Ride Control (APRC):

Aprilia equipped the RS 660 with a full suite of rider aids, including:

Traction Control – Ensures optimal grip in all conditions.
Wheelie Control – Helps manage front-end lift for smoother acceleration.
Engine Braking Control – Allows customization for different riding styles.
Cruise Control – A rare feature for sportbikes, making highway rides more comfortable.
Quickshifter – Enables seamless clutchless upshifts and downshifts.
Five Riding Modes – Adjustable for street, track, and wet conditions.

TFT Display & Connectivity:

The RS 660 also features a full-color TFT display with smartphone connectivity, giving riders access to navigation, calls, and music—features usually reserved for high-end touring bikes.

A Perfect Balance of Sport & Everyday Usability

Unlike aggressive supersport bikes that demand an extreme riding position, the RS 660 strikes the perfect balance between sporty ergonomics and everyday comfort. The slightly raised handlebars and comfortable seat make it a viable option for daily commutes and long weekend rides, without sacrificing aggressive cornering capabilities.

Comparison to Competitors:

When compared to the Yamaha R7, Kawasaki Ninja 650, and Honda CBR650R, the RS 660 stands out due to its superior power, advanced electronics, and lightweight design. While the Yamaha R7 and Ninja 650 offer solid performance, they lack the refined electronics and racing pedigree of the RS 660.

Track-Ready Performance Without the Liter-Bike Intimidation

Despite being street-friendly, the RS 660 is no slouch on the track. Its high-revving engine, lightweight chassis, and advanced rider aids make it an exciting choice for track days.

Professional riders and motorcycle journalists have praised its sharp handling and precise throttle response, noting that it feels like a true racing machine but without the intimidating power of a 1000cc superbike.

Aprilia’s Influence on the Future of Middleweight Sportbikes

Aprilia’s success with the RS 660 has forced other manufacturers to rethink their approach to middleweight sportbikes. Brands are now focusing more on high-tech, lightweight, and rider-friendly motorcycles. The RS 660 has set a precedent, and we’re likely to see more bikes adopting similar design philosophies in the coming years.
