DescriptionThe whole story

Few motorcycles get modified as consistently as the MT-07, and almost none of those modifications touch the engine. Owners change what they touch and what they look at, which puts the ignition barrel high on the list: a black plastic cylinder sitting in the middle of a cockpit Yamaha otherwise kept deliberately bare.

Key Features

  • Fits the Yamaha MT-07 from 2014 to 2020
  • Barrel, lock and key come off the motorcycle for good
  • Drops roughly 350 g from the fork crown
  • Choice of black, blue or titanium anodising
  • Ergal billet body with a sealed IP69K button
  • Key Box supplied, so the transponder circuit is unaffected

Why the Immobiliser Still Works Afterwards

Yamaha reads a chip in the key head through a coil wrapped around the barrel. Take the barrel out on its own and the bike is dead. The Key Box is the answer to that and it is not a workaround: the original key goes inside the housing, the housing plugs into the same antenna, and the electronics see precisely what they saw before. Nothing is cloned, emulated or defeated — the security system is simply somewhere else.

A Note on the Blue

Yamaha's Icon Blue is one of the few factory colours the aftermarket bothers matching, and JP KS YA003 B is anodised to sit alongside it. Titanium (JP KS YA003 T) suits the grey and Storm Fluo schemes; black (JP KS YA003) is for owners who would rather not notice the part at all.

Reversibility Matters on a Used Bike

MT-07s change hands often. Because this swap cuts nothing and solders nothing, the standard ignition block can go back on before a sale with no evidence it was ever removed — which is worth more on a bike in this class than the 350 g, and worth remembering before deciding the original parts can be thrown away.

Fitment and Compatibility

Road Approval

None. The lock is part of the motorcycle's type approval, so a road-registered MT-07 fitted with this switch no longer complies. Sold for closed-circuit and competition use.
