DescriptionThe whole story▼
The JP ACC TR039 is the ride-by-wire quick throttle for the Speed Twin 900, machined from solid and built to reach wide open in a considerably shorter sweep of the hand.
Key Features
- Triumph Speed Twin 900 (2025–2026)
- 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 Smaller Twin
Triumph's 900 cc parallel twin in a roadster chassis with cast wheels and a low seat. It is the accessible end of the modern classic range and it is ridden gently by most owners.
Bar End Weights
They unbolt from the tube and go back into the new one on most models. It is worth checking the thread before ordering anything exotic.
Why Sixty and Not Less
Below about sixty the hand runs out of useful resolution and small inputs become unusable. It is a chosen figure rather than the shortest possible one.
Not for Every Bike in the Garage
A commuter gains nothing here. The part earns its place on a machine ridden hard, where the throttle is worked rather than held.
Half an Hour Plus the Appointment
The mechanical work is short. What takes the planning is the diagnostic session that has to follow it before the bike is ridden.
What It Does Not Do
No extra power, no different fuelling, no change to any rider aid. Anybody expecting the motorcycle to accelerate harder has misread the part.
A Component That Reports
The grip's only output is an angle. Everything a rider feels afterwards is the controller's interpretation of that angle through whichever mode is selected.
Who This Suits
A rider who opens and closes the throttle deliberately on a machine ridden hard enough that the hand runs out of rotation first. Track riders, fast road riders and anybody with small hands notice it at once. A commuter in traffic gains nothing at all.
Riding With Others
A sharper hand response makes smooth following harder for the first hour. Anybody planning to use the part behind somebody else's rear wheel should get the solo miles in first, which is good advice for any control change.
