DescriptionThe whole story

The JP ES KIT18 is the complete PAIR removal package for the 600 RR: cover, gasket and solenoid eliminator together.

Key Features

  • Honda CBR 600 RR (2007–2026)
  • Complete PAIR removal kit: cover, gasket and solenoid eliminator
  • Plug-and-play on the original connector
  • Fully reversible to standard

Both Halves in One Box

The mechanical cover closes the ports and the electrical eliminator keeps the ECU quiet. Buying them separately works; buying them together avoids the half-finished job.

Why Half Does Not Work

A blanked port with a live solenoid stores a fault. A dead solenoid with open ports still admits air. The two parts only make sense as a pair.

What the System Was For

Injecting fresh air into the exhaust ports so unburnt fuel finishes burning there. It lowers measured emissions and it produces the popping on a shut throttle.

Before Any Fuelling Work

Air arriving downstream of combustion corrupts the lambda reading. Nobody should map a 600 RR with the secondary air system still connected.

A Gasket, Not Sealant

The cover seals with a proper gasket. Beside an exhaust port a hand-applied bead hardens within weeks and then leaks.

Nineteen Years, One Kit

Honda left the 600 RR's head arrangement alone from 2007 through to the current bike, which is why a single kit covers the entire run.

Emissions Approval

Removing the system takes the motorcycle outside its type approval. This is a closed-circuit modification and the description says so.

Nothing Permanent

The original cover, gasket and solenoid all refit. The cylinder head itself is never modified.

An Afternoon

Tank off, cover swapped, connector changed. It is among the more satisfying jobs on a 600 because the result is audible the first time the throttle closes.

Audible on the First Ride

Most modifications need a stopwatch or a dyno to prove they did anything. This one announces itself the first time the throttle closes at the end of a straight, because the popping that everybody blames on the exhaust simply stops. It is a rare case of a change being obvious without any instrumentation at all.
