Spark Exhaust Grid-O Euro5 3/4 Kit High Lateral Black Box Triumph Street Triple 765 (2020-2022) GTR0505BOM

The top of Spark's modular range for this generation. High lateral mounting, the Moto2 Grid-O silencer, and the black ceramic box — every option taken, and still an approved exhaust.

Key Features

• Euro5 approved 3/4 kit for the Triumph Street Triple 765 R, RS and S, 2020 to 2022.
• High lateral silencer mounting.
• Grid-O silencer, full titanium, 2020 Moto2 world champion case.
• Black ceramic treatment on the pre-silencer box.
• Catalysed AISI 304 stainless box, racing cell count.
• Compatible with the passenger footrests.

What Each Step Costs

The range is priced so you can see exactly what you are choosing. The standard low mounting with the Grid-O and a bare box is the base. Moving the silencer to the high lateral position adds two hundred and twenty-seven euros. Adding the black ceramic treatment adds a further hundred and forty-three.

Neither step changes the catalyst, the approval, the silencer or the performance. They change where the exhaust sits and what colour the largest part of it is. Laid out like that the decision is easy to make honestly — and easy to stop halfway through if only one of the two matters to you.

When the Whole Stack Makes Sense

There is one configuration where both options work together rather than merely adding up. In the high lateral position the silencer is what you see, and the box below it is what you do not want to see. A black box under a raw titanium silencer pushes the contrast the right way: the expensive part reads bright, the structural part disappears.

In the low mounting that logic is weaker, because both components sit in shadow anyway. If you are going to specify the black box on this bike, this is the version where it does the most work.

What Has Not Changed

Spark measured this family at 97 dB at 5,850 rpm, the same figure it recorded for the standard Triumph exhaust, and the kit saves 2.6 kg against the 6.2 kg section it replaces.

The pre-silencer box is where both of those come from: very thin-walled AISI 304 built on current tooling, holding a catalytic converter with a rich noble-metal impregnation. Spark's design brief was more performance with no ECU modification, and it is met with an efficient catalyst rather than a restrictor.

Fitment & Compatibility

Triumph Street Triple 765 R, RS and S, 2020 through 2022. Without the ceramic treatment it is GTR0505TOM. The same high position with the Moto GP silencer is GTR0506TOM in titanium and GTR0506DOM in dark style. The standard low mountings are GTR0503TOM, GTR0503BOM and GTR0504DOM. Mounts on the standard collector or Spark's GTR8502.

Road Approval

Approved. Spark states compliance with Euro 4 and Euro 5 regulations, with the catalytic converter inside the box.
