This is the maintenance schedule for the Triumph Trident 660, a mid-size roadster from Triumph released in 2021, including the A2 / LAMS-approved version.
The Triumph Trident has the same name as its forebear from many years earlier, but it’s an all-new motorcycle. It has an inline three-cylinder engine (a “triple”) with 660cc of displacement, running a compression ratio of 11.95:1 for max power of 60 kW or 80 hp at 10250 rpm in unrestricted form.
The Trident 660 is also available in learner-legal form in many markets, including Europe, the UK, Australia, and New Zealand. Parts and maintenance are the same — it’s restricted but nothing fundamental changed in the build.
Being an all-new bike, it doesn’t have in common much with the Triumph Street Triple S, the LAMS-approved bike for some markets. But it does effectively take a portion of its market share.
The Triumph Trident 660 shares an engine and basic platform with Triumph’s entry-level adventure sport bike, the Triumph Tiger Sport 660.

About the Triumph Trident 660

The Triumph Trident 660 is an entry-level naked roadster, Triumph’s entrant into the “middleweight sports” category, a rapidly expanding market for motorcycles. It’s also a bike available in A2 or LAMS-restricted form, which means it can be learner legal in Europe and the Asia-Pacific.
It’s designed to appeal to a wide range of riders:
- Casual riders who don’t want the most intense sportbike possible, and don’t want to spend that much
- New riders on their learner licenses (A2/LAMS) who want the same bike, just conforming to legal requirements
- People with a sense of nostalgia about the triples of old…
Unlike the Triumph Speed Triple and Street Triple bikes, the Trident 660 is not a high-strung sportbike. It’s not a bike people would buy intending to race (other than for fun!), and so its components — while not cheap as chips — are lower end than the other bikes, and aren’t designed to be pushed too hard.
But that isn’t to say the Trident 660 isn’t well-equipped —it is. It comes with competent tech right out of the box, including
- A ride by wire throttle
- Standard ABS (of course)
- Switchable traction control
- Two ride modes
- A TFT display
- All-LED lighting
- A slip and assist clutch (a relative rarity in its budget class)
The Triumph Trident 660’s motor revs happily above 10000 rpm — though not much further. But the speed and grace with which it gets there means that it’s a bike you’ll really enjoy flinging about back country roads.
The torque curve is extremely flat, with most of its torque available on a wide plateau between 3000 and 9000 rpm. This makes it really easy to ride in a range of styles from everyday commuting to getting RPMS up in back roads.
The suspension and braking area also capable too. It comes with Showa upside down forks, though they’re non-adjustable, and a Showa preload-adjustable monoshock with a remote reservoir.
The non-adjustable nature of the front suspension is just one thing that differentiates the Triumph Trident 660 from higher-end alternatives, like the Aprilia Tuono 660, which has fully adjustable suspension (and costs about 50% more).
But the Trident’s spec is still on the upper end compared to most middleweight road bikes.
Some competitors to the Triumph Trident 660 are other middleweight motorcycles like the Kawasaki Z650, Honda CB650R, the Yamaha MT-07, and the Ducati Monster 659, which are all available in learner-legal incarnations in some markets.
