Jetprime - Precision Control, Supreme Quality Jetprime Enlarged Water Pumpfor MV Agusta F4 Brutale At engine speeds below 4700 RPM, the stock water pump has a very slow coolant recirculation speed which is caused by the large gap between the rotor and the pump cover. The result of this is a huge inconvenience to the performance and comfort for anyone who uses their MV Agusta bike everyday or just for the classic Sunday ride. For example during the summer you only need to be stuck in a traffic jam or to stop at a traffic light to cause the temperature to rise to 115-117 degrees. To then bring the temperature back down to 90 degrees requires several kilometres of sustained speed riding which is not always possible (especially in city conditions). Our enlarged water pump can increase the recirculation of engine coolant by up to 46% and has been developed by our company with the help of several important teams who use the 312 RR in race conditions. It is possible to fit the pump on all MV Agusta motorcycles whether it be the Brutale or the F4. The unit is CNC Machined from 7075 T6 aluminium. All the normal fixings, bearings and the shaft can be purchased as original spare parts from any MV Agusta dealer and in this way you will have peace of mind that all of the parts which work with the engine are completely safe and compatible.
