DescriptionThe whole story▼
A period-shaped silencer on a modern homologated system. Spark closes this Trident 660 exhaust with the 60's case from its modern-classic range — the option for an owner who wants the weight and the certificate without a race silhouette under the tail.
Key Features
- Homologated full system for the Triumph Trident 660, Tiger Sport 660 and Daytona 660.
- 60's silencer from Spark's modern-classic range.
- AISI 304 stainless steel collector and pre-silencer box.
- Racing catalytic converter, heavily impregnated with noble metals.
- Certificate issued by the Italian Ministry of Transport.
- The least expensive homologated system Spark builds for this bike.
A Silencer That Suits the Motorcycle
The Trident is a roadster with a deliberately unfussy line, and not every rider wants a MotoGP stub or a Grid-O grid hanging off it. The 60's is Spark's answer to that: a period-correct silhouette from the modern-classic range, offered alongside the Evo V and Gp Style cases.
It is the only silencer in Spark's Trident programme that is not derived from a racing part, and on a bike whose appeal is its plainness that is a coherent choice rather than a compromise.
A Note on the Name
Spark's product page for this code names the silencer as the 60's. The dealer price list files the same part under Evo V — both are cases from Spark's modern-classic range, and the discrepancy is in the paperwork rather than in the box.
We have gone with the product page, because it names the silencer for this specific code rather than assigning a family. If you are matching an invoice that says Evo V, this is the same article.
How It Stays Legal
The approval comes from two components ahead of the silencer: a racing catalytic converter heavily soaked with noble metals, and a pre-silencer box in AISI 304. Together they let Spark meet the homologation requirements with a certificate from the Italian Ministry of Transport.
Spark asks buyers to check the homologation numbers against their vehicle documents — e9*168/2013-2020*11674, e9*168/2013-2019*11675 and e9*168/2013-2020*11675, engine code U. If your registration shows something else, ask us before ordering.
What Three Kilos Do to a 660
Spark quotes 4.9 kg for the racing version of this system against 8.1 kg standard. On a 660 twin-purpose roadster that is a larger proportion of the motorcycle than the same figure would be on a litre bike.
It also comes off high and to one side, where the standard silencer hangs. A Trident is already an easy motorcycle to place; taking three kilos off the part of it that swings furthest is the change a rider notices at walking pace as much as at speed.
Fitment & Compatibility
