It’s 2026, and the middleweight sportbike category is hotter than a desert track day. Aprilia has just raised the stakes again with the 2026 RS 660 Factory, a machine that proves you don’t need a liter-bike to have a world-class experience on the asphalt.
Here is the lowdown on why this Italian masterpiece is currently the bike to beat.
1. That Overhauled 659cc Parallel Twin
Aprilia didn’t just tweak the engine; they transformed it. The updated powerplant delivers more torque across the rev range, but it’s the character that steals the show. It’s got a visceral, snarling exhaust note that makes every downshift a symphonic event. It’s punchy, reliable, and pure fun.
2. Featherweight Agility
At just 400 lbs, the RS 660 Factory feels like an extension of your own body. Whether you’re flicking it through a tight chicane or hauling it off the kickstand in the paddock, the lightness is palpable. This weight-to-power ratio makes it exceptionally approachable for intermediates and a surgical tool for experts.
3. A Brain Faster Than Your Own
This bike is packed with “electronic bells and whistles” that would make a MotoGP engineer blush. We’re talking:
- Adjustable engine power and throttle maps.
- Precise engine brake control.
- Launch and wheelie control.
- Cornering ABS: Our personal favorite for that extra safety net at full lean.
- Electronic Quickshifter: Seamlessly keeps the engine “on the boil.”
4. Sleek Bodywork & Improved Ergonomics
The 2026 model features aggressive new bodywork that looks “sick” and performs even better. For the taller riders out there, there’s good news: the front fairing is now wider and more comfortable, offering better wind protection when you’re tucked in on the straights.
5. Premium Performance, Italian Style
For $13,999, you’re getting a bike built in Italy with a two-year warranty and a pedigree of racing excellence. It’s a middleweight that doesn’t feel like a compromise—it feels like a choice.
