DescriptionThe whole story

The JP ES KIT05 is the complete PAIR removal package for the MT-03: cover, gasket and solenoid eliminator.

Key Features

  • Yamaha MT-03 (2016–2025)
  • Complete PAIR removal kit: cover, gasket and solenoid eliminator
  • Plug-and-play on the original connector
  • Fully reversible to standard

Both Halves Together

The plate closes the ports and the eliminator keeps the ECU quiet. Bought separately they work; bought together they arrive as one finished job.

Why Half Achieves Nothing

A blanked port with a live solenoid stores a fault. A dead solenoid with open ports still admits air. Only the pair actually removes the system.

What Is Being Removed

Secondary air injection into the exhaust ports, fitted so the motorcycle passes emissions testing. It has no effect on power and a considerable effect on the overrun.

The Popping Stops

Fresh air meeting unburnt fuel in a hot header is the noise. Close the passages and it goes, without touching a single fuelling value.

A Gasket, Not Sealant

Included with the cover. Beside an exhaust port a hand-applied bead hardens within weeks and then stops sealing altogether.

A Naked R3

The same 321 cc twin with wide bars and an upright seat. The MT-03 is the easier of the two to ride quickly on anything that is not a circuit.

Emissions Approval

Removing the system takes the bike outside its type approval, which makes this a closed-circuit modification wherever the rules are enforced.

Ten Model Years

The fitment covers 2016 to 2025 without a change in the emissions hardware. One kit spans the entire production run.

Nothing Permanent

Cover, gasket and solenoid all refit. The cylinder head is never modified in the process.

Wide Bars Change Everything

Yamaha altered the riding position and almost nothing else when it turned the R3 into the MT-03. On a small twin that must be revved, real leverage and an upright seat make the bike considerably easier to ride quickly on a road.
