BT Moto (21-27) Aprilia 660 Velocity Stack Kit

2021-2027 Aprilia 660 Velocity Stack Kit

With the success and amazing feedback we've gotten from our Aprilia flashes and RS660 velocity stacks, we wanted to turn our focus to getting into the engine in a more efficient way. Our custom revised velocity stacks and revised tuning not only give a very decent, top-end power increase, but also doesn't lose any power in the low or midrange of the RPM. Our easy to install, custom velocity stacks don't shift the powerband over and decrease power down low. We managed to make more power where it matters without sacrificing that torquey punch we've grown to love on the 660 platform.

Experimenting with many designs, we found a design that works perfectly for this bike. We spent months testing and developing these stack designs, even testing competitor offerings to see how we could improve our own design. We ended up with a design that makes the best power for the 660 (see dyno tab). With our custom stack tuning, there's no need to worry about your bike having rideability issues either.
