DescriptionThe whole story▼
The JP MJ 004 corrects what a homologation map costs the F 800 S at part throttle, which is where almost all road riding actually takes place.
Key Features
- BMW F 800 S (2006–2016)
- 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 Early Sports Version
Before the GT there was the S, a half-faired 800 twin that BMW positioned against the Japanese middleweights and priced like a German one.
Type Approval
In markets where the fuelling forms part of the motorcycle's emissions approval, altering it puts the machine outside its approved condition. That is a legal question rather than an engineering one and it is worth settling locally.
Removal Before a Service
Five minutes with the seat off returns the motorcycle to standard. Whether that is necessary depends on the dealer and the term, but the option existing at all is part of what the product is.
Against Flashing the Controller
A full remap can do considerably more and is considerably harder to undo. This module is the narrower, cheaper and entirely reversible option, and for a great many owners that is the right trade.
The Alternative Costs More
A specialist remap with dyno time is several times the price and is written into the original controller. It can achieve more; it is also considerably harder to reverse.
The Legal Note
Fuelling is part of the emissions approval in most of Europe. A modified mixture puts the machine outside its approved condition, and that is a local question with a local answer.
Not an Exhaust Substitute
A module changes fuelling, not gas flow. Riders hoping for the noise or the weight saving of an aftermarket silencer will be disappointed, because it does neither of those things.
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.
