The advent of the Speed 400 and Scrambler 400 X might mean Triumph’s Trident 660 is no longer the brand’s entry-level model, but it remains the lowest-cost route onto one of the company’s signature triples and has proved a huge success since its debut four years ago. For 2025 the Trident gets its first round of updates, and while they’re not visible they represent a substantial step forward in terms of tech and come with no increase to price in the US.
Triumph says that since its launch in 2020 the Trident 660 has become its most popular model with female riders, and with a three-cylinder engine and 81 hp in a market segment where rivals—most notably the Yamaha MT-07—make do with two cylinders and a bit less power, it’s a tempting proposition. The changes for 2025 only serve to sweeten the deal further and take the lead on rider-assist tech that will add further elements of safety to a bike that’s often bought by less experienced riders.
“Cheap as chips” is a distinctly British term (equivalent to “dime a dozen”), and while it originates from the low cost of what we call french fries on this side of the Atlantic, it could just as easily refer to computer chips in the third decade of the 21st century. It’s that low cost of computing power that allows Triumph to give the Trident most of its 2025 improvements. The addition of a six-axis inertial measurement unit, the sort of thing that was exclusive to high-end superbikes just a few years ago, means the 2025 Trident gains lean-sensitive cornering ABS and traction control as standard. Affordable computing power also means Triumph has been able to add its Triumph Shift Assist quickshifter (complete with downshift blipper) and cruise control to the bike for 2025. The Bluetooth Connectivity module, previously an option, has been made standard to give phone connectivity and turn-by-turn navigation on the small TFT display that sits below the LCD that shows speed and rpm in the upper section of the single, circular instrument. An ambient temperature display is also added, as well as an additional Sport riding mode to accompany the existing Road and Rain settings.
But the changes aren’t purely in the bike’s computers. While the on-paper specs of the suspension seem like the original version, with a 41mm inverted Showa fork and a preload-adjustable monoshock from the same brand, the parts are new. The 2025 model upgrades to Showa’s SFF-BP (Separate Function Fork-Big Piston) fork, with tweaks to the setup including slightly softer springs and firmer damping to give a better balance of comfort and response. The top triple clamp is new, too, made of forged aluminum, and the same material is used for the new rear brake pedal.
The main spec figures for the bike are unchanged, including the aforementioned 81 hp output from the 660cc triple at 10,250 rpm, with 47 lb.-ft. of torque at 6,250 rpm. Weight rises by 2.2 pounds thanks to the additional electronics and components like the quickshifter. But the most important unchanged number—in the US market at least—is the MSRP: it stays at $8,595, the same as the 2024 model.
