DescriptionThe whole story

The JP KS AP660 answers the Tuono 457's ignition circuit with a button rather than a barrel, and leaves every other control on the motorcycle alone.

Key Features

  • Aprilia Tuono 457 (2024–2026)
  • Replaces the original ignition block, key and lock
  • Around 350 g off the top yoke
  • CNC-machined from solid Ergal
  • IP69K sealed push button
  • Plug-and-play on the motorcycle's own connector

The Naked Small Twin

Same engine as the faired 457 with the bars raised. It is a first motorcycle for a lot of riders and a first track bike for some of them.

Three Hundred and Fifty Grams

That is the manufacturer's figure for what leaves the top yoke. It is a small number in a place where mass matters more than most.

The Colours

Black as standard, with blue, red and titanium anodising on the numbers that offer them. The finish is the only choice to make.

Vibration

A button on a yoke sees more of it than one on a handlebar. The body is machined and the switch is sealed for that reason.

Fitting Time

Twenty minutes on most models, longer where the loom sits under the tank. Nothing about the job needs the front end apart.

Access

Reaching the connector generally means lifting the tank or a cover. On some models it is visible as soon as the block is unbolted.

Scrutineering

Series differ on stop controls. A sealed button in the standard position satisfies most, but the rulebook is the only authority worth consulting.

US Market Bikes

A few models carry a separate number for the American specification, because the ignition circuit there is arranged differently.

What Fails on Cheap Switches

Water past the seal, then corrosion on the contacts, then an intermittent connection nobody can find. The rating on this one exists to prevent exactly that.

Regulations and Scrutineering

Championships set their own rules about how an engine must be stoppable and where the control sits. A sealed button in the standard yoke position satisfies most of them, but the rulebook is the only authority worth consulting and it is worth reading before ordering.
