Akrapovič Has Two New Exhaust Options For 2021 Aprilia RS 660
One Street, One Track
It ain’t an Aprilia if it isn’t screaming like a MotoGP track bike… Right? Akrapovič – the industries leading exhaust manufacturer – has two full exhaust systems ready for the 2021 Aprilia RS 660 motorcycle.
The Racing Line (S-A6R2) is a carbon fiber exhaust that will rely on your stock ECU mapping (this is a major benefit; you will avoid the expensive tuning cost to have your motorcycle run properly with the new airflow metrics) with a 2.5 horsepower increase at 11,200 rpm and 2.7 lb-ft bump in torque at 4550. This exhaust will also shed a pound off the wet weight of your motorcycle.
S-A6R1 is the “track use” (haha) variant that aims to bring 3 horsepower and 5 lb-ft of torque while also shedding 2.5 pounds from the weight of your ride. This exhaust won’t keep your ride Euro 5 compliant, however.
