Meet the RS 660—a standout in the Sport category. Engine mapping and suspension aside, your physical connection to the bike dictates your control. Featuring a well-balanced chassis, a seat sitting at 32.3″ (820 mm), and a fueled weight of 403 lbs (183 kg), checking your ergonomic compatibility is the first metric you need to evaluate.
Let us examine how these static dimensions translate to real-world comfort and the steps you can take to customize the fit.

💡 Ergonomics & Expert Take
The Aprilia RS 660 presents a rider triangle that balances aggressive sportbike posture with street usability. While the 32.3-inch (820mm) seat height is notable, its relatively narrow waist at the tank junction mitigates excessive leg splay, though ground reach remains a factor for shorter riders. Knee bend is pronounced for those over 6 feet (183cm) on extended rides. The 403-pound (183kg) wet weight makes low-speed maneuvers surprisingly light and manageable, belying its displacement. Its 100 hp engine and 48 mpg fuel economy position it perfectly for spirited commuting, weekend canyon carving, and light sport-touring, rather than dedicated long-distance touring or off-road capability.
