Presenting the Jetprime upgrade kit for your BMW R1150 GS.
The kit consists of 2 pistons which have been developed to our specifications and are lighter than the OEM units. Each piston weighs only 135 grams each and have an increase in the compression ratio which has been taken to 12:1 compared to the standard 10.2:1.
In addition to the pistons we have also fitted a non catalized pipe and two cam sprockets with modified timing to change the lower torque to about 1000 rpm.
This has meant only one thing; more power and a more responsive throttle response with less mechanical stress on all of the internal parts with an already exciting torque at low revs.
At the request of the client and paired together with this kit, it is also possible to have the cylinder heads prepared where we take care of every detail and improve the fluid dynamics leading to a truly satisfactory result which you can see in the test bench result chart.
All of this should of course be finished with an accurate remapping of the ECU.
