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 RSV4.\n\u003c\/p\u003e\n\u003cp\u003e\n Experimenting with many designs, we found a design that works perfectly for this bike. We spent months testing and developing these stack designs. We have found this design makes the best power for the RSV4 (dyno results below). With our custom stack tuning, there's no need to worry about your bike having rideability issues either.\n\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e\n BENEFITS\n \u003cbr\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n  Custom velocity stack designed for YOUR airbox.
