About the Aprilia RS 125

Powered by a Euro 4 compliant liquid cooled 124.2cc single cylinder four stroke engine, producing 14.8bhp 

Slightly confusingly the 2017 RS125 replaces the 2011-2016 RS4 125, which itself replaced the 2006-2012 two stroke RS125 In the majority of countries, however still continues to carry the RS4 moniker in some!

compared to the previous version it is Euro 4 compliant and now comes with ABS.

Optional Extras include a quickshifter, USB port and smartphone connectivity.

There is a MotoGP Replica edition which includes the quickshifter.
