Bazzaz Fuel Injection Unit for Panigale 899 works perfectly, great improvemnts in throttle response and power. A must to prevent engine damage if you've changed to high flow filters or aftermarket exhaust. Even a standard bike can be much improved by adding more "fuel-air" as manufacturers run bikes lean to get over the emission tests. Comes with 2 X O2 eliminators. This piggy backs the ECU, so dosen't have the risks flashing the ECU does. A broken ECU costs a lot of money!!!
