Four Cylinders Lying Down
BMW's inline four sits almost flat in the frame, which keeps the mass low and gives the motorcycle a wheelbase nobody expects from a sports bike.
Constant Throttle Surging
A lean cruise setting produces a slight hunting at steady speeds that riders learn to ignore. It is the most common complaint about modern fuel injection and it is the thing a fuel module is best placed to address.
No Laptop Required
JetPrime works out the curve for that engine and ships it in the module. There is no software to install, no cable to buy and no afternoon spent learning an interface, which is the entire point of the preset version.
Between the Loom and the Injectors
The module is wired in series with the injector circuit, which is the least invasive place to intervene in a modern motorcycle. Everything upstream carries on unaware and everything downstream simply receives a slightly different instruction.
A Question of Expectations
Bought as a power part it will disappoint. Bought as a smoothness part it consistently satisfies, and the manufacturer's own description says which of the two it is.
A Component That Disappears
Once fitted it requires nothing further. There is no season of adjustment, no software update and no reason to think about it again.
Riding Modes Still Work
On a ride-by-wire machine the rain and sport settings continue to shape the throttle exactly as before. The module operates downstream of all of that and cannot see which mode is selected.
Fitting It in Winter
There is no reason to wait for good weather. The job happens in a garage, needs no test ride to complete and the result is available on the first dry morning.
