DescriptionThe whole story

Not a part — a service. Spark repacks the silencing box of its Super Duke racing collector rather than selling you a new one, and at a fraction of what the collector costs it is the sensible answer to the maintenance Spark itself asks for.

Key Features

  • Factory repacking of the silencing box in Spark's Super Duke racing collector.
  • For the GKT8502 and GKT8503 collectors, KTM 1290 and 1390 Super Duke R.
  • Restores the sound-absorbing packing rather than replacing the box.
  • Around a seventh of the price of a new collector.
  • The box has to be sent in — this is a service, not a shipped item.
  • Spark recommends checking the packing every 15,000-20,000 km.

Why a Box Needs Repacking

The silencing box in Spark's racing collector contains sound-absorbing material, and that material is a consumable. Exhaust gas passing through it at high temperature and high velocity gradually blows it out and breaks it down.

What follows is not a failure but a drift: the exhaust gets louder over months, and because it happens slowly the rider rarely notices until a sound check does. Spark asks for the packing to be checked every 15,000 to 20,000 kilometres, or sooner if the box changes colour — a discolouring box is packing that has been running hot.

Repack or Replace

Most manufacturers offer only the second option. Spark listing a regeneration service means a box that has done its kilometres does not become a reason to buy a new collector.

The arithmetic is straightforward: the service costs roughly a seventh of a complete collector. For a bike that is ridden regularly on track, where packing goes faster than on the road, that difference repeats every couple of seasons.

How This Order Works

This is a service and not a shipped product, so it works differently from everything else on this site. The box has to reach Spark, be repacked and come back — please contact us before ordering so we can arrange the shipment and give you a realistic turnaround for the current workload.

If your motorcycle has to stay usable in the meantime, say so when you get in touch. That is worth planning around rather than discovering afterwards.
