PRO CIRCUIT Throttle Body Kit - RMZ250 1740230

Developed by TRIGA Engineering, a company from the Netherlands that uses state-of-the-art 3D software and top-level technical knowledge to engineer, develop and produce high performance fuel injection systems 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 The flow-engineered butterfly valves and shaft are CNC-precision-machined from steel, which allows for less material use and optimal shape to eliminate high-end flow loss by lowering flow restriction 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 TRIGA TPS Tool (sold separately) is needed to recalibrate the TPS sensor after installing the TRIGA valve and shaft; correct TPS sensor calibration is essential to the performance of the IBoost2 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 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 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 The TRIGA butterfly valve reduces restriction in the throttle body, which decreases overall pressure drop over the throttle body at full throttle TRIGA-TBI improves the volumetric efficiency of the engine by applied Pressure Wave Tuning (PWT) Kits include TRIGA's Throttle Body Insert (TRIGA-TBI) and TRIGA Butterfly Valves (TRIGA-TBV) Butterfly valve and shaft eliminates high-end flow loss by lowering flow restriction Can be installed in a stock bike without changing the fuel mapping or tuning Can be installed and uninstalled without damaging the OEM throttle body Option 1 can significantly increase horsepower in low, mid and top range Significant increase in torque and power throughout the power band Throttle body insert improves the volumetric efficiency of the engine Option 2 can significantly increase horsepower in top range Kit offers two installation configurations Allows for significantly better throttle response No service necessary after installation Easy-to-use and install
