Pro Circuit - i Boost 2 Throttle Body KitPro Circuit i Boost 2 Throttle Body Kit Included in the kit: Throttle Body Insert (TRIGA TBI) Improves the volumetric efficiency of the engine by applied Pressure Wave Tuning (PWT). Up and down running pressure wave in the intake system is tuned to ensure the positive peak of the pressure wave is there when the intake valve opens. Using the TRIGA tubular insert will slightly reduce the overall flow area, which will allow enhanced speed over the valve

Pro Circuit - i Boost 2 Throttle Body Kit

Included in the kit:
Throttle Body Insert (TRIGA-TBI)

  • Improves the volumetric efficiency of the engine by applied Pressure Wave Tuning (PWT).
  • Up and down running pressure wave in the intake system is tuned to ensure the positive peak of the pressure wave is there when the intake valve opens.
  • Using the TRIGA tubular insert will slightly reduce the overall flow area, which will allow enhanced speed over the valve while timing the pressure waves for low and mid-range power improvements.
  • On the track, using the TRIGA butterfly valve will increase top-end power. The TRIGA tubular insert will utilize some of this extra power and distribute it over the entire rpm range.

TRIGA Butterfly Valves (TRIGA-TBV)

  • The flow-engineered butterfly valves and shaft are CNC precision machined from steel, which allows for less material use and optimal shape.
  • Eliminates high-end flow loss by lowering flow restriction.
  • Throttle control via the butterfly valve is known for its low-flow loss up to 75% of TPS. The high range flow is more restricted because the valve is still horizontally present.
  • The TRIGA butterfly valve reduces the restriction in the throttle body, which decreases the overall pressure drop over the throttle body at full throttle. This results in higher velocity for improved fuel droplet breakup. This also improves the fuel-air mixture while allowing more air mass flow to enter the combustion chamber. More air, more fuel, more power.
  • On the track, using the TRIGA butterfly valve will increase top-end power. The TRIGA tubular insert will utilize some of this extra power and distribute it over the entire rpm range.

Additional Features:

  • 2 installation configurations
  • Option 1 can significantly increase horsepower in low, mid and top range
  • Option 2 can significantly increase horsepower in top range
  • Easy-to-use and install
  • Significant increase in torque and power throughout the power band
  • Throttle body insert improves the volumetric efficiency of the engine
  • Butterfly valve and shaft eliminates high-end flow loss by lowering flow restriction
  • Can be installed and uninstalled without damaging the OEM throttle body
  • Allows for significantly better throttle response
  • No service necessary after installation
  • Can be installed in a stock bike without changing the fuel mapping or tuning

Seems complete…
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
I haven’t actually used this kit yet, but it appears to be very complete. The price is good and based on what I see at this point, I would purchase it again.

Good fit and quality - careless packaging
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
OK - I'm happy with most of the kit. The dead corner brushes are crammed into small bag and bent out of shape. It looks like 2 of the 6 in the kit I received might be usable. Since I can get 3 of these for the cost of the OEM kit, I suppose I'm still ahead of the game, but it would be nice if a little more care was taken in the packaging.

Better than original.
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
The pads are better than originals. A little bit thicker. They fit very well for a good price.
