British Invasion: Triumph Confirms Two New Enduros

Class-leading power and torque, top-shelf components, and advanced electronics: That’s what Triumph is promising with its all-new TF 250-E and TF 450-E off-roaders. Both bikes are purpose-built for enduro racing duty, and according to Triumph, they’re both hitting the ground running with a major head start.

That’s because the two bikes were developed under the testing and direction of Iván Cervantes and Paul Edmondson, two World Enduro heavyweights with nine collective championships between them. Both machines have been built specifically for competition use, and will see action in events like the SuperEnduro World Championship later this year.

It’s a move we’ve seen from Triumph before. Back in 2021, the brand hired none other than the winningest MX racer of all time, Ricky Carmichael, to develop Hinckley’s first entities into the fiercely competitive world of motocross.

And while the new enduros clearly benefit from Triumph’s current off-road racing efforts, these aren’t just reworked versions of the current 250-X and 450-RC motocrossers. Both the engine platforms and chassis are all new according to Triumph, and are tailor made to meet the demands of competitive enduro racing.

The list of factory bling is long, but a few highlights paint a clear picture: Triumph’s aims to storm the podium this season.

Starting with the engines, both the 250cc and 450cc liquid-cooled singles utilize Del West titanium valves paired with forged Konig pistons. Triumph says this ensures both engines can handle sustained high-rpm performance while also minimizing regular service requirements.

Both engines are fed by bespoke 44mm Dell’Orto throttle bodies designed specifically for Triumph. These components incorporate a manual adjustment for idle speed as well as an air-bypass system for easy cold starts, essentially a choke for the modern era.

In the case of the 250-class engine, the result is a claimed 41.7 peak horsepower and 20.5 lb.-ft., as well as a screaming 12,800 rpm redline. The 450 model further benefits from diamondlike coatings on its gudgeon pin and rockers to minimize friction, and makes a claimed 57.8 horses and 35.6 lb.-ft. of torque.

Triumph has also collaborated with the folks at Athena to design all-new engine management systems, codeveloping engine mapping and traction control strategies that are unique for both models. The bikes feature dual engine maps selectable by a switch on the handlebar, while additional maps can be designed and added wirelessly via the Triumph MX Tune Pro app.

On the chassis side of things, the two new enduros share a lightweight aluminum spine frame, which is TIG-welded by hand and optimized for stiffness and a low center of gravity. Beefy 48mm coil-sprung KYB fork handles suspension duty up front, while a KYB shock riding on three-way-adjustable linkage is utilized out back. Travel is reduced by about half an inch compared to Triumph’s current motocross offerings to give a better balance of handling, cornering performance, and bump absorption.

Braking duties are handled by Brembo front and rear, with a dual-piston floating caliper up front and a single-piston floater in the rear. Galfer branded discs bump up the bling factor even further with a 260mm dish up front and a 220mm unit in the rear.

Other notable standard equipment includes D.I.D DirtStar 7000 Series rims, adjustable ProTaper CarbonCore handlebars, a Pyramid nonslip seat, and Michelin Enduro 2 tires. Taken all together, the new Triumphs are poised to do some damage on the enduro circuit scene this year.

The TF 250-E and TF 450-E models will have a starting MSRP of $9795 and $10,795, respectively. Preorders are open now at Triumph dealerships nationwide, and deliveries are scheduled to begin in June.
