DescriptionThe whole story▼
The JP MJ 004 gives the K 1300 R a fuel curve tailored to that engine rather than to every market the model was ever sold into.
Key Features
- BMW K 1300 R (2009–2016)
- 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
The Naked K
Stripping the K1300 produced one of the strangest looking motorcycles BMW has ever built and one of the fastest naked bikes of its decade.
Response Rather Than Power
The manufacturer's claim is throttle response and smoothness, not horsepower. Anybody expecting a figure on a dyno sheet has misread the product. What changes is how the engine answers a small movement of the hand, which is where most riding actually happens.
Where Manufacturers Run Lean
Cruise, small openings and the range the emissions cycle measures. Those are the conditions a test procedure examines, and they are also the conditions a rider spends most of their time in on a road.
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.
Not a Season-Long Project
Some tuning components lead to a winter of adjustment. This one is fitted in an afternoon and then behaves identically for the next decade.
What Is Supplied
The module and a harness made for one motorcycle. The owner supplies twenty minutes, a cable tie and somewhere sensible to put it.
On a Motorcycle With Two Owners
A shared machine ridden by somebody who does not know the module is there will notice nothing at all. It changes nothing about how the motorcycle is operated, only how it responds.
The Owner Who Should Not
Someone chasing a number, someone with a standard and recent motorcycle, or someone who would rather have a full remap done properly by a specialist.
