DescriptionThe whole story

The JP ES KIT01 is the complete secondary air deletion for the RS 660: the electrical eliminator and the head blank in one part number.

Key Features

  • Aprilia RS 660 (2020–2026)
  • Both halves of the secondary air deletion
  • Solenoid eliminator plus the head blank
  • One part number, one fitting session
  • No drilling and no splicing
  • Every standard part refits afterwards

Two Problems, One Box

The controller watches a solenoid and the cylinder head carries a reed housing. Solving one and not the other leaves either a warning on the panel or an open port on the engine.

Why Not Order Separately

Bought apart, the two halves usually arrive weeks apart. The tank comes off twice and a two-hour job spreads across two evenings for no reason.

The Order of Work

Seat, tank, hose, housing, blank, connector. Following that sequence means nothing has to be undone and repeated.

No Diagnostic Afterwards

The circuit is satisfied rather than suppressed, so the panel is clear from the first start and no dealer session is needed to clear anything.

A Hundred Horsepower, 183 Kilograms

The RS 660 is quick because it is light. On a tight circuit that produces lap times a considerably more powerful motorcycle would not deliver.

Before Any Mapping

Air entering the exhaust after combustion shifts what a wideband sensor reads. Every fuelling decision taken afterwards inherits that shift.

Nothing Modified

Aprilia's own connector, Aprilia's own fastener positions and Aprilia's own torque figures throughout the whole job.

A Wind Tunnel Fairing

The double skin moves hot air away from the rider and adds downforce at speed. Aprilia designed it rather than styled it.

Homologation

Secondary air is part of the bike's approval and removing it makes the motorcycle a competition machine in Europe.

Reversible Both Ways

Keep the housing and the plug and the bike returns to standard in the same two hours it took to convert.

A Six-Axis Platform on a Middleweight

Aprilia fitted full inertial measurement to a hundred horsepower twin when rivals were still reserving it for litre bikes. The rest of the class took three years to answer and several competitors have still not matched the implementation.

The Bike That Restarted the Class

Aprilia's 660 arrived when nobody was building light sports bikes any more and made the case that the market still existed. It is modified heavily by owners because it responds to the work.
