The silencer lifted out from under the tail and carried high beside it. Spark's high lateral mounting is the most visible of the three positions it offers on the 2020-2022 Street Triple 765 — and it stays Euro5 approved.
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, Moto2 world champion case.
- 3.6 kg against 6.2 kg standard — 2.6 kg saved.
- Catalysed AISI 304 stainless box.
- Compatible with the passenger footrests.
Three Positions, One Bike
Spark builds this half system in a standard low mounting and in this high lateral one, and the difference is four hundred grams and two hundred and twenty-seven euros. Nothing else changes: same box, same catalyst, same silencer, same approval.
The extra weight is mounting hardware. A silencer carried high and outboard needs a longer, stiffer bracket than one tucked against the swingarm, and that bracket is the difference on the scales. Whether the position is worth it is a question about the motorcycle you want to look at, not about the exhaust.
What High Mounting Changes
Two practical things follow from lifting the silencer. It moves out of the rear wheel's spray, which matters on a bike ridden in the wet — road grime and salt collect on a low silencer in a way they do not on a high one. And it raises a hot component closer to the pillion seat and the rider's leg, which is why the mounting hardware includes proper spacing.
The third thing is ground clearance, and it is the one riders notice. A high-mounted silencer cannot be the first thing to touch down.
Racing Case, Road Certificate
The Grid-O here is the same full titanium silencer Spark developed for the World Superbike and Moto2 teams, with visible TIG welding and a titanium grid. It won the 2020 Moto2 world championship.
It is approved in this kit because of what sits in front of it: a very light AISI 304 pre-silencer box with a special catalytic converter inside, built with racing cell count and a rich noble-metal impregnation. Spark's design goal was a deeper sound and more performance with no ECU modification, and the box is what makes both legal.
Fitment & Compatibility
Triumph Street Triple 765 R, RS and S, 2020 through 2022. With the black ceramic box it is GTR0505BOM; with the Moto GP silencer in the same position GTR0506TOM and GTR0506DOM. The standard low mounting is GTR0503TOM. 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.
