Aprilia made public in January 2019 about the RS 660 concept . Motor box spied the new video of Aprilia RS 660 on track at Cremona Stradivari Circuit.
The video shows testing of RS 660 on track Cremona Stradivari Circuit in spite of bad weather. Painted in black so as not to recognize. The RS 660, when brought on track, made the sound similar to that of a new parallel twin that is capable to produce 100 hp of power.
The bike will get an upside-down fork, swingarm made up of aluminum and calipers that are radially mounted. RS 660 will closely compete with Honda CBR 650R. We are waiting for its launch at EICMA 2019.
