DescriptionThe whole story

The JP ES KIT19 gives the SuperSport 939 one part number for a job that would otherwise be two orders and two evenings with the tank off for both of them.

Key Features

  • Ducati SuperSport 939 (2017–2020)
  • Both halves of the secondary air deletion
  • Solenoid eliminator and cylinder head cover
  • One part number, one fitting session
  • No drilling and no splicing
  • Every standard part refits afterwards

Renamed the 950

Ducati updated the model in 2021 with V4-derived bodywork and a new name, which confuses used listings considerably.

Both Halves in One Box

The connector that satisfies the controller and the machined blank that closes the head. Ordered together they cost less than the two parts bought apart.

On a V4

Four cylinders in a very compact package means everything on the rear bank needs the airbox out before it can be reached at all.

Where the Money Goes

Two machined and potted components rather than a bolt and a resistor. The price reflects the work in them rather than the function.

What Actually Improves

A tidier top end, one fewer perishable component and a clean diagnostic panel. Nobody should expect anything beyond that.

Torque Into the Head

The figure is low and specified for good reason. It is the single number worth looking up before starting.

The Torque Figure

Ducati specifies a low value for the head fasteners, and exceeding it is the commonest way a twenty-minute job turns into a thread repair and a considerably longer weekend.

Completely Reversible

Nothing is cut, drilled or soldered anywhere in either half. Both original components refit on their own hardware with no replacement seals needed, which is what makes an emissions inspection or a resale a conversation rather than a problem.

Photograph the Hose Routing

Before anything is disconnected, a picture of how the lines run costs a minute and answers every question that comes up during reassembly. It also settles which fitting at the airbox has to be closed, which is the detail most often discovered too late.
