DescriptionThe whole story▼
The JP ACC TR039 shortens the Speed Triple 1050 S's throttle travel for riders who open it deliberately, and asks for a diagnostic reset once the assembly is on the bar.
Key Features
- Triumph Speed Triple 1050 S (2018–2020)
- Ride-by-wire quick throttle with a sixty degree rotation angle
- CNC-machined from solid Ergal
- Plug-and-play on the motorcycle's own connector
- Diagnostic reset required after fitting
- Standard throttle assembly refits at any time
The Base Specification
The S carried the same engine and frame with conventional suspension, which made it the version bought by riders who used it every day rather than at weekends.
Plug and Play
The original connector carries over and nothing in the loom is cut. Fitting is mechanical and the electrical side is a plug moved from one body to another.
Cruise Control
Where the motorcycle has it, the system continues to operate through the same inputs. The grip's mechanical ratio is not something it reads.
Winter Gloves
Thick gloves eat rotation. A shorter sweep means the same hand position works in January that worked in July.
Aftermarket Bars
A different bar can change where the switchgear sits and how much room the assembly has. Worth measuring before ordering rather than after.
Grips With a Bonded Sleeve
Some factory grips are moulded onto the tube and cannot be recovered. Budget for a new pair rather than discovering it halfway through.
The Part Nobody Reads About
The reset. It appears in one line of the manufacturer's own description and it is the single most important sentence in it.
What the Reset Does Not Do
It does not adjust the part, tune the engine or change any map. It teaches the controller where closed now sits and nothing else. Anybody expecting a workshop visit to make the motorcycle faster has misunderstood which half of the job is which.
Cleaning It
Anodising tolerates the chemicals a motorcycle meets and does not tolerate a wire brush, which is true of every anodised part on the machine. Beyond that the finish outlasts the rider's interest in it.
