Aprilia RS4 50 Euro4 Changes for 2018
Posted: Sat Jul 28, 2018 1:39 am
Thanks to Berkeley we have some photos of the new equipment installed on the Euro4 engine in the 2018 RS4-50 bikes.
This line looks like it come off the pipe, into a hose that passes through a check valve, and then goes into the air box. Probably to capture unburnt fuel.
There is a completely new CDI unit. Not sure what the extra connectors do yet. Hopefully a workshop manual for these new engines will pop up soon.
The pipe also has a lot going on with it.
