MWR Velocity Stacks 2021- Aprilia RS660
Additional freight required on orders placed outside the USA
MWR has developed new high performance velocity stacks for the new RS 660!! Why you ask? Well small bikes can only make so much power, but why restrict that with less than efficient parts? Once you install the new MWR airiflter in your RS and start getting the right amount of air into your bike, you quickly realize how deficient the OE stacks are since they were designed with that horribly restrictive filter in mind!
The new MWR Stacks are larger and have a much better bell curve and profile than the OE! Designed completely in-house, the MWR Stacks succeed in your quest to get the best power out of your bike, you will need to replace parts like these that are just poorly designed and the results speak for themselves.
