DescriptionThe whole story▼
The JP MJ 001 corrects the mixture on the RSV4 without touching the original controller, its adaptations or its fault memory in any way.
Key Features
- Aprilia RSV4 (2009–2026)
- Preset fuel module, no programming required
- Corrects the mixture without remapping the original electronics
- Plug-and-play with model-specific wiring
- Around 200 g, fitted in an evening
- Unplugs at any time, nothing is written to the motorcycle
A Very Short Inlet Tract
Aprilia's narrow sixty-five degree vee lets the airbox sit almost on top of the throttle bodies. The result is a filling behaviour that rewards precise metering and punishes a coarse one.
Nothing Is Reprogrammed
The standard controller keeps its own map, its own adaptations and its own fault memory. A workshop plugging in a diagnostic tool finds the motorcycle exactly as the factory left it, which is a genuine advantage over flashing the original unit.
Plug and Play, Literally
The harness ends in the connectors the motorcycle already uses. They separate, the module goes in between and they close again. Nobody needs a wiring diagram and nobody needs to strip insulation.
Model-Specific Wiring
JetPrime supplies the harness for the chosen motorcycle with the correct connectors moulded on. It is the part of the product that costs the most to develop and the part nobody thinks about.
One Harness Per Motorcycle
The connectors differ between models and sometimes between years of the same model. That is why this is sold per machine and why the year span in the listing is worth reading before ordering.
Original Electronics Intact
This bears repeating because it is the product's main structural advantage: nothing is written to the motorcycle. Every parameter, adaptation and stored fault remains the factory's.
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.
What the Seat Hides
On most modern motorcycles the injector harness runs under the seat within reach of the fuel pump connector. That is why so many of these installations are a twenty-minute job.
