DescriptionThe whole story▼
The JP ACC YA043 is the ride-by-wire quick throttle for the R1M, machined from solid and built to reach wide open in a considerably shorter sweep of the hand.
Key Features
- Yamaha R1M (2020–2024)
- 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 Race Kit Version
Yamaha's own race kit harness changes what the electronics expect at the bars, which is why a separate throttle assembly is listed for machines running it.
Machined From Solid
Ergal cut on a machine rather than moulded, which is what allows the internal ratio to be held to a figure instead of to a tolerance band.
Riding Modes
Rain, road, sport and whatever else the manufacturer offers all continue to work exactly as they did. The assembly reports an angle and nothing more.
Scrutineering
Nothing here affects a technical inspection at a circuit. The assembly is a standard-looking part in a standard position doing a standard job.
One Colour
Black anodised is what the manufacturer makes. There is no finish to choose and nothing to specify beyond the model.
Cable Guides
Nothing routes through the assembly on a ride-by-wire motorcycle, which is one of the few things that makes this job shorter than the same work on an older bike.
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.
The First Ride
Somewhere open, quiet and dry. Open it deliberately half a dozen times from a settled position and let the hand recalibrate. The adjustment takes an afternoon rather than a season, but the first corners genuinely feel abrupt and traffic is the wrong place to find that out.
When Not to Fit It
On a machine used mostly in traffic, mostly two-up or mostly on gravel. The part rewards deliberate throttle use and punishes casual throttle use, and there is no setting to change that balance afterwards.
