DescriptionThe whole story▼

The JP ACCGP YA019 fits the 2026 Yamaha R7, a supersport built around a parallel-twin engine rather than the four-cylinder layout of its bigger siblings, and shortens the throttle stroke to suit the bike's role as an accessible way into track riding. The progressive return spring and milled Ergal housing follow the usual GP Series layout.

Key Features

  • Yamaha R7 (2026)
  • 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

A Twin Where You Might Expect a Four

The R7 uses the CP2 parallel-twin engine shared with Yamaha's mid-weight roadsters rather than an inline-four, which gives it a broader, more usable spread of torque lower in the rev range than a typical supersport. That character rewards smooth, early throttle inputs more than it rewards a long, dramatic twist near redline.

An Accessible Way Into Track Days

Yamaha built the R7 to be the bike riders move onto before stepping up to something with more weight and more power, and that intent shapes how it is normally ridden: more trackday laps, more passes through a riding school, fewer riders already fluent in every input the bike offers.

Resistance That Builds With the Twist

The GP Series spring stays soft near idle and firms progressively as the throttle opens, which suits a rider still learning exactly how much input a given corner needs. That curve forgives a slightly early or slightly late throttle crack more readily than a flat spring rate would.

Milled from Solid Ergal

The housing is machined from a single billet of 7075 aluminium instead of being cast, producing a part that holds its tolerances through the repeated, sometimes clumsy throttle inputs typical of a rider still building confidence on a track-focused bike. It is a strength margin most owners never think about.

Fatigue on a Learning Curve

New track riders tend to grip harder and move the throttle more than necessary simply because they are still learning what the bike needs, which tires the hand faster over a full day of sessions. A shorter stroke reduces how far that overcorrection actually travels each time it happens.

A Short Procedure After Fitting

Once the throttle is installed, a brief relearn on a diagnostic tool lets the ECU recognise the new throttle position sensor, a step most riders handle at the same time as any other post-fit check before the bike goes back out.
