DescriptionThe whole story▼
The JP MJ 004 gives the Trident 660 a fuel curve tailored to that engine rather than to every market the model was ever sold into.
Key Features
- Triumph Trident 660 (2021–2025)
- 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 Triple at a Twin's Price
Triumph brought three cylinders to a class dominated by twins and undercut almost everything. It feels like more motorcycle than the numbers suggest.
An Evening's Work at Most
Seat off, tank lifted on some models, connectors separated, module plugged in and tied down. There is nothing to configure and nothing to learn afterwards, which is unusual for anything electronic on a motorcycle.
Buying With an Exhaust Already Fitted
This is the most common situation and the clearest case. A motorcycle running an aftermarket silencer on the standard map is working with a mixture the factory never intended it to have.
What Riders Report
Cleaner pick-up from a closed throttle, less hunting at a steady speed and a general sense that the engine is less reluctant below four thousand. Those three come up again and again.
Consumption, Honestly
No meaningful change either way. Anybody who reports a large difference has changed their riding at the same time, which is what usually happens after fitting anything to a motorcycle.
Invisible to the Rider Aids
Traction control and the rest read wheel speeds, lean angle and throttle position. None of them can see an injector pulse being lengthened.
A Note on Dyno Runs
A power run measures full throttle from low revs to the limiter. That is one line through a map with hundreds of cells, and it is not the line this module was designed to change.
Where the Development Happens
JetPrime works the curve out on their own equipment for each engine family. That is invisible in the product and it is the entire reason a preset module can work at all.
