BTM-RSV4-STKKT
With the success and amazing feedback we've gotten from our Aprilia flashes, we wanted to turn our focus to getting into the engine in a more efficient way. Our
custom velocity stacks
and revised tuning not only give a very decent, top-end power increase, but also don'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.
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.
*VELOCITY STACKS DO NOT REQUIRE FLASH PURCHASE, BUT IT IS RECOMMENDED FOR ADVERTISED RESULTS*
Custom composite with our logo and torque specs etched into them, the BT Moto Velocity Stacks have been carefully engineered and designed to maximize power in the higher RPM range while not losing power in the low RPM range.
Made for an OEM fit, the BT Moto velocity stacks bolt to the airbox to ensure tight fitment while also being easy to install. These are plug-and-play and require no additional modifications to your airbox to fit. Simply remove your factory velocity stacks and install. Coupled with our custom flash, the combination makes an extremely easy install and tune that can be done in your own garage, with basic tools and minimal mechanical knowledge.
