Hey Ernet,

All of the RS 660’s have LED lights integrated into the mirrors. You can see that in the group shot here:

Hope this helps,

Hey Douglass,

Great question and I didn’t experience any numbness from vibrations, personally. The vibes are there when you’re on the gas, but I still don’t think it’s a deal-breaker. I would say that the stock barends begin to lead to the larger side. You can check them out in the photo gallery.

Take care!

Hi Dano,

The Suzuki GSX-R750 is a great bike, but it’s quite different from the Aprilia RS 660. A supersport like the GSX-R750 is subject to the main criticisms of inline-four cylinder supersports, like a lack of low-end torque and a committed riding position best suited for the racetrack. The Aprilia RS 660 comes at sport riding from a different angle by offering ergonomics with road riding in mind, but racetrack capable, and a parallel-twin engine that makes significantly better low-end and mid-range power, which is what street riders depend on.

Sure, a Suzuki GSX-R750, Yamaha YZF-R6, Kawasaki ZX-6R, Honda CBR600R, and any other four-cylinder supersport will have more top-end power, pulling away from the RS 660 on a long straight, but that doesn’t apply to street riding. Where the Aprilia RS 660 has a leg up is its maneuverability since its noticeably lighter, smaller, and more agile. Its chassis is matched to the levels of performance that its p-twin engine produces, which definitely boosts confidence for riders of any skill level. Also, parallel-twin engines are often known for being fuel-efficient, which allows a bike like the RS 660 to get away with a 3.96-gallon fuel tank capacity. By comparison, the GSX-R features a 4.5-gallon tank and isn’t too much larger. During our first ride, I’d routinely see 60 mpg listed on the active readout when cruising, but I’d estimate a 150+ range can be achieved pretty easily, even with spirited riding. Toss in the electronics, and the RS 660 strikes a unique balance that isn’t offered elsewhere at the moment.

“Better” is a tough question to answer since we aren’t comparing apples to apples, and ultimately, it’ll come down to intended use.

Take care!

Not to mention what is the deal with these too small fuel tanks on every single bike these days? Some of us like to ride and need some range.
