2025 Triumph Trident 660 Arrives With Big Spec Upgrades

Triumph added a bit of three-cylinder fun to the middleweight sector in 2020, as its then-entry-level Trident 660 naked was revealed. Quick, good looking and priced competitively, the Trident was an instant hit with new riders and journalists alike.

That’s not to say there’s not some room for improvement, though, and four years since we first tested the bike, its second-generation version has just been revealed. If you were a fan of the original bike, fear not. Stylistically speaking it’s still very much a Trident, although with a swatch of new colours and graphic options to choose from, its arguably better looking than ever.

What’s new on the 2025 Triumph Trident 660?

Mechanically the bike is very much like the one it supersedes, and while there were mutterings that the bike would gain the sportier engine as found in the Daytona 660 with its individual throttle bodies, that turns out to be untrue. What you get then is a liquid-cooled inline three-cylinder engine, producing a claimed 81bhp and 47lb ft of torque. The standard spec of the bike has been upgraded for 2025, though, as the new bike will be fitted with a quickshifter as standard.

Further upgrades come in the form of upgraded suspension thanks to Showa SFF Big Piston internals now arriving on the mid-weight naked bike. The rear suspension still comprises a Showa rear shock absorber which is adjustable for preload only. As before, the Trident 660 is halted by Nissin two-piston callipers and 310mm discs at the front and a single piston 255mm disc at the rear. The braking system of the bike also receives a boost in spec thanks to the inclusion of cornering ABS replacing the traditional two-channel system found on the outgoing model.

Another welcome electronic update for the incoming bike is the inclusion of cruise control as standard, which isn’t a given in the segment. The only other option you could consider as being a mid-weight A2-restrictable naked that gets it is the more high-performing and much more expensive Aprilia Tuono 660.

Happily for us, as we are quite fond of the styling of the Trident, Triumph hasn’t altered the look of the bike except for a load of bold new colours and graphic options. Some of the materials used have been altered, though, including a new forged aluminium top yoke and a forged aluminium brake pedal. 

Colour options for 2025 include Cosmic Yellow, Cobalt Blue, and Diablo Red, with touches of Sapphire Black and diagonal white stripes. There is also a more stealthy Jet Black colour scheme for those looking for a more moody aesthetic.

2025 Trident 660 price and availability

The 2025 Trident 660 will be available from £7,895 OTR for the Jet Black option, and £7,995 for the coloured options. Bikes can be configured now on the Triumph website and bikes are expected to be in dealerships in December.
