DescriptionThe whole story

Spark's price list calls this one the bivio raccordo — the fork connector. It is the fitting at the branch of the GAP8806 collector, in titanium, listed separately at 404 euro so a damaged junction does not mean a new collector.

Key Features

  • Junction fitting for the Spark GAP8806 collector.
  • Aprilia RS 660 and Tuono 660, 2020 to 2026.
  • Titanium.
  • Replacement part, sold individually.
  • Racing part, no homologation.

Where a Twin's Pipes Meet

On a parallel twin the two header pipes have to come together before the silencer, and the fitting that does it sees more than its size suggests: the pressure waves from both cylinders arrive here, and the geometry of the junction is part of what the collector was tuned around.

It is also a stress point. Two pipes pulling in slightly different directions through heat cycles work on the joint between them, and a junction is the section that shows it first.

Why Spark Numbers It

Because the alternative is expensive. The complete collector is 1,180 euro. Replacing one fitting at 404 keeps a repairable system repairable, which is the whole logic behind Spark listing the collector, the junction, the silencer connector and the silencer group as four separate articles.

Confirm Before You Order

Spark publishes no separate page for this fitting, and the designation in the dealer list — bivio raccordo — describes where it sits rather than giving a dimension.

If you have a damaged section in front of you and want to be certain this is the right number, send us a photograph together with the number stamped on the collector. We will check it against Spark's breakdown rather than let you order on a guess.
