DescriptionThe whole story▼
The JP ACCGP TR039 brings the GP Series short-stroke throttle to the Triumph Daytona 660 (2024–2025), an entry-level supersport built around a triple engine, shortening the rotation to sixty degrees from a milled 7075 Ergal housing while the ride-by-wire fuelling stays exactly as Triumph calibrated it.

An Accessible Supersport With Real Ambitions
The Daytona 660 is positioned as an approachable entry into fully-faired sport riding, built around a triple rather than the inline-fours some rivals use, and riders stepping up into this category for the first time often notice throttle feel before almost anything else about the bike.
Where New Riders Feel the Wrist Working
Clip-ons stretch the wrist further than an upright bar does, and for a rider newer to that posture, the standard throttle's full rotation can feel like more work than it needs to be; shortening it gives back some of that travel from the very first ride.
Sixty Degrees Instead of the Standard Sweep
Cutting the rotation to sixty degrees means the same opening the factory grip needed a wider sweep to reach now happens over a shorter arc, with the triple's ride-by-wire mapping behind it left completely untouched by the change in hardware.
A Diagnostic Reset Before the First Ride Out
Once the new grip is fitted, the ride-by-wire control unit needs a short procedure to relearn the throttle position sensor's range, a step any workshop comfortable with modern Triumph electronics can complete in a matter of minutes rather than hours.
Milled Rather Than Cast for a Reason
The housing starts as a solid block of 7075 Ergal rather than a casting, machined down to its final shape so the lever's action holds up to daily use rather than loosening over time the way a cheaper, cast part eventually would.
Nothing Stops a Return to the Standard Grip
The factory throttle refits cleanly at any point, which means a rider new to the Daytona 660 can try the shorter rotation without committing to it before they have had time to judge whether it genuinely suits their own riding style.
