Dave at Dynobike gets his hands on an Aprilia RS660 to see what gains can be had after installing some components. Then dialling in on the Dyno.
The Customer’s Aprilia already had a full exhaust system fitted but had some higher flowing Velocity stacks and DNA installed.
As you will see from the results via the below video, some great gains were made right throughout the entire rpm range.
If you would like a similar set up you can follow see below.
