The MotoPressor Mini Pump enables you to pre-select a tyre pressure, pump your tyres and the pump will automatically switch OFF when it reaches the pre-selected pressure. Here’s how it works. Connect the MotoPressor Mini Pump to either your motorcycle battery OR a mini jump starter. Select a pressure scale either PSI, BAR or KPA. Select the pressure you would like to pump your tyres to. Switch the pump ON, stand back and let the pump do the work. Once the pump reaches the pre-selected tyre pressure it switches OFF automatically. The kit includes the pump with a digital pressure gauge and all the power leads and connectors to enable you to run off your motorcycle battery or a mini jump starter. All this is packed neatly into a sturdy carry case. Weighs 503g, dimensions 127 x 105 x 53 mm, pumps to a max 100psi and will pump a 120/70 R19 tyre to 36psi in 3min 20sec and a 170/60 R17 tyre to 40psi in 6min 45sec.
