VELOCITY STACKS

DUCATI

Our ATR50 are made exclusively for the Panigale 1199 / R 1299, for racing use.
Their shape allows to improve the venturi effect of the standard velocity stacks and is perfectly connected with the throttle body.
The injector support is very thin and aerodynamic, so as to disturb as little as possible the incoming air flow.
These intake funnels are made of ergal 7075-T6 with the most modern CNC machines and are designed and manufactured entirely within our company.
They are mounted on the bike without any modification inside the air box using the petrol tube and the standard injectors.
The assembly is very simple, but we recommend, however, if you do not feel confidant, to contact workshops that are well familiar the bikes of Borgo Panigale.

BMW

Our Velocity Stacks for BMW S 1000 RR have a very particular and original shape in the motorcycle world.
They increase the power of the bike and make the thrust very smooth, without declines.
The maximum of their performance is achieved at the engine speed in which they rise to let the lower fixed velocity stacks breathe, from that moment their function becomes that of cleaning the flow of air that is channeled towards the throttle body. Like most of our products, it is machined from solid with CNC machinery to always have the maximum precision and reproducibility.

FOR YAMAHA TMAX 500 AND 530

These velocity stacks we have developed for the TMAX are necessary to improve the air intake during the phases of opening the throttle control.
Due to the particular shape, this allows a reduction in air turbulence during the suction phase, improves the air intake from inside the air box, facilitates the intake and reduces the response time of the engine especially when you have a violent opening of the throttle.
The shape and length of the velocity stack has been studied by our design department to reconcile the engine at different engine speeds, to increase the suction strength and to improve the coverage at low engine speeds.

The velocity stack is mounted inside the air box and is connected to the intake manifold directly on the throttle body. The stacks have been developed for specific uses: a BLUE series for the throttle body of the TMAX 500, a BLACK series for the throttle body of the TMAX 530 and a GOLD series which is designed to be mounted on our enlarged 36, 38 and 40mm throttle bodies. The test bench results show an increase between 2-3 bhp in comparison to the OEM fitted unit.
As with any changes made to the engine, this also requires the correct setup of the injection to obtain the best possible results from this modification.
