DescriptionThe whole story▼
The JP MJ 004 smooths out the Rocket III's throttle response at small openings, which is where a map written to pass an emissions test is at its most cautious.

Two and a Third Litres
Triumph's inline three is the largest production motorcycle engine anybody makes, and its fuelling is about managing torque rather than finding it.
Warranty
A dealer will see an additional module the moment they lift the seat. On a motorcycle still inside its term the sensible course is to unplug it before an appointment, which takes minutes and leaves no trace at all.
Weight and Space
Two hundred grams and a body about the size of a matchbox. On most motorcycles the harder part is finding somewhere tidy for the cable rather than for the module.
A Component, Not a Project
Some tuning parts start a conversation that lasts a season. This one is fitted on a Sunday afternoon and then never thought about again, which for most owners is exactly the point.
Fitted After an Exhaust
The order matters. A silencer changes the mixture, and judging what the module then contributes is only possible if one change has already settled.
At Resale
Off in minutes, into a box, and the motorcycle is standard. Or left on and mentioned in the advertisement. Neither choice damages anything.
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.
If the Bike Runs Worse
Unplug it and ride the same road. Ten minutes settles whether the module is responsible, which is a diagnostic luxury that reflashing the controller does not offer.
