DescriptionThe whole story▼
The JP ACCGP TR039 fits the Tiger 800, bringing the electronic throttle's rotation down to just 60 degrees. Triumph's mid-size adventure triple keeps its ride-by-wire mapping untouched by the swap; only the mechanical travel the grip covers to reach full throttle is shortened.
Key Features
- Triumph Tiger 800 (2018–2019)
- GP Series ride-by-wire quick throttle with a sixty degree rotation angle
- Progressive return spring, preload adjustable externally in three positions
- CNC-machined from solid Ergal 7075
- Plug-and-play on the motorcycle's own connector
- Standard throttle assembly refits at any time
Equally at Home on Either Surface
The Tiger 800 was built to be credible both on a motorway and down a forest track, and throttle control matters differently in each setting. A shorter rotation keeps inputs direct on tarmac while still allowing the fine control needed when traction is uncertain off it.
One Solid Block
The housing is machined from a single billet of Ergal 7075 aluminium, not assembled from cast pieces. Every bearing surface and spring location is cut to the same tolerance, which keeps the mechanism running smoothly even after sustained use on rough ground.
A Spring That Does More Work
The progressive return spring behind the shortened throw provides more resistance as the throttle opens further, rather than a constant light pull throughout. That makes it easier to hold a steady partial throttle on a loose surface without the grip feeling like it wants to spring fully shut or fully open.
The 800 Triple's Spread
Triumph's triple in this generation of Tiger offers a wide usable spread of revs, and a shorter throttle throw brings that spread closer to the rider's hand, useful both for motorway overtakes and tighter trail sections. It is the kind of change that shows up most clearly when switching quickly between the two.
Everything Else Stays Put
The Tiger 800's switch cluster, including any heated grip or mode controls fitted, stays exactly where it was after the new throttle goes on. Only the grip and the mechanism behind it are different. Anyone familiar with the standard cockpit layout will find nothing unfamiliar after the swap.
A Short Relearn
Fitting finishes with a throttle position relearn through the bike's diagnostic port, a quick step most workshops can complete without a lengthy appointment. It is usually finished in the same visit as the physical installation of the new unit. It usually adds only a few extra minutes to the overall appointment at the workshop.
