DescriptionThe whole story▼
The JP MJ 001 gives the CVO Street Glide ST a fuel curve tailored to that engine rather than to every market the model was ever sold into.
Key Features
- Harley Davidson CVO Street Glide ST (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
The Performance Bagger
The ST specification drops weight and adds output, aimed at the bagger racing that has become surprisingly serious in America.
And With an Open Filter
More air on the intake side has the same effect from the other direction. The standard closed-loop correction handles part of it and runs out of authority for the rest, particularly at larger throttle openings.
No Laptop Required
JetPrime works out the curve for that engine and ships it in the module. There is no software to install, no cable to buy and no afternoon spent learning an interface, which is the entire point of the preset version.
The Case Against Buying It
A late model motorcycle with the standard exhaust, ridden gently, is already mapped about as well as it needs to be. The honest advice there is to spend the money on tyres.
Dealers and Terms
It unplugs in minutes. Owners inside a warranty period generally remove it before an appointment and refit it afterwards, and the connectors are designed to tolerate that repeatedly.
Sequence With an Exhaust
Fit the silencer, ride it, then fit the module. Two changes at once tell the rider nothing about either, and the exhaust is the one that moves the mixture furthest.
Buying Second Hand
A motorcycle offered with one fitted should come with the original connectors intact underneath. Checking that takes a minute with the seat off and settles whether anything was cut.
Tank Off Models
A minority of machines route the harness under the tank, which turns the job into an hour. The listing does not say which, so a look underneath before ordering saves an evening.
