Overview
Triumph's entry-level roadster and the base of its 660cc triple platform, shared with the Trident's siblings the Tiger Sport 660 and Daytona 660. Sold in Australia since 2020 in LAMS form; a full-power version was added locally alongside a 2025 model-year refresh (cornering ABS, traction control, quickshifter, cruise control standard) at the same ride-away price as the LAMS bike. A three-cylinder engine in this class is unusual — most learner and near-learner naked rivals are twins — and it is the character difference buyers are paying for, not just the extra parts count.

Pros
- Inline triple gives a distinct exhaust note and mid-range pull unlike any twin in this class
- Cornering ABS, traction control, quickshifter and cruise control standard on the 2025-on refresh
- Sold at the same ride-away price as the LAMS version, so no premium for the extra power
- British-designed with a genuine factory dealer network in Australia
Cons
- Too new in the Australian used market for an established fault pattern
- Triple-cylinder servicing (three sets of everything) costs more than a comparable twin at an independent workshop unfamiliar with the platform
- Heavier and less parts-common than the deeply-established Japanese naked twins it competes with
Known problems

No documented model-specific faults yet
On sale in Australia only since 2020 (LAMS) and 2025 (full power), too recent for the kind of high-kilometre used-market fault pattern already documented for the long-running Japanese platforms on this site.
Fix: Get a full authorised-dealer service history, and use a Triumph-experienced workshop for anything beyond routine servicing.
660cc inline triple (LAMS) LAMS approved
Same 660cc triple as the full-power bike, restricted by the ECU. Listed on the NSW, QLD and VIC registers.
Check it's actually the LAMS one
Compliance-plate model code:
LG23
- NSW lists it as "LG23: Trident 660 - LAMS", 2024-on, 660cc; the original 2020-on approval sits under NSW's "L Series" heading.
- Queensland and Victoria list it by name: "Trident 660".
- Every row on these lists is an approved bike, so a listing without the word LAMS is still an approval.

Pros
- Same triple-cylinder character and chassis as the full-power bike, not a decontented learner model
- Strong mid-range torque for a LAMS bike, inherited from the extra cylinder
- Sold at the same price as the full-power version, so no premium is paid for the restriction
Cons
- 660cc is right at the LAMS capacity ceiling, leaving less margin than a smaller-capacity rival
- Too new in the Australian used market for an established fault pattern
- Triple-cylinder servicing costs more than a comparable twin at a workshop unfamiliar with the platform

No documented model-specific faults yet
On sale in Australia since 2020, but this is still a relatively young and low-volume platform locally compared to the long-running Japanese LAMS naked bikes on this site.
Fix: Get a full authorised-dealer service history, and use a Triumph-experienced workshop for anything beyond routine servicing.
