If you weren’t on an Aprilia RS 660 Factory during the 2024 MotoAmerica Bellissimoto Twins Cup Championship, you were always going to be up against it.
Suzuki did an admirable job with the determined Rocco Landers and Yamaha had a peek or two with Dominic Doyle, but, in truth, the RS 660 in the hands of 15-year-old champion Alessandro Di Mario was the class of the field.
Aprilia was more than happy to have finally dethroned Yamaha, and they have no intention of giving up the crown and have released a new RS 660 for 2025 to ensure that doesn’t happen.
The main talking point is the RS 660 gets a five horsepower increase for 2025, now rated at 105 hp and with 4 mm larger 52 mm throttle bodies (the eagle-eyed among you may have noticed that 52 mm throttle bodies are a thing for 2025 with all manufacturers—you can thank Euro5+ emissions regs for that).
The cast aluminum twin-spar chassis stays the same but the RS 660 Factory is graced with fully-adjustable 43mm Ohlins NIX30 forks and the fully-adjustable Ohlins STX 46 shock—which is much higher-spec gear than you’ll find on the Suzuki GSX8-R or the Yamaha YZF-R7 it competes against.
The electronics now include Launch Control to go along with the ATC (adjustable and switchable traction control), AWC (adjustable and switchable wheelie control), ACC (cruise control, allowing the rider to maintain a set speed without using the throttle), AQS (bidirectional quick-shifter), AEB (adjustable engine brake control), and AEM (multiple engine maps that modify power delivery characteristics). As before, the Aprilia RS 660 comes standard with an electronic Ride-by-Wire throttle and a six-axis inertial platform that houses Cornering ABS.
Oh, and there’s new front winglets, because everyone needs wings on a 105 hp bike…
It’ll set you back a pretty handsome $13,999 and you can expect to see them in dealers around March of 2025.
As for the base model RS 660, you’ll get the 105 hp motor with the 52 mm throttle bodies, launch control, backlit switch gear (same as the Factory), but you don’t get the fancy Ohlins suspension, instead you’ll get KYB units, but at least they’re still fully-adjustable. Expect to pay $11,649 MSRP for the base RS 660 and they’ll be in dealers March 2025.
