Triumph TF 250-C and TF 450-C land as purpose-built cross-country weapons

Triumph is doubling down on its off-road ambitions with the launch of two new cross-country models, the TF 250-C and TF 450-C. Developed to take on the demanding world of GNCC-style racing, the new bikes are not just motocross machines with bigger tanks bolted on. They are purpose-built from the ground up to combine endurance, control and the sharpness of Triumph’s already proven motocross line.

Available from October 2025, both models are packed with features designed for long-format racing. Think revised suspension settings, an 8.3 litre fuel tank, rider aids that make life easier when fatigue sets in, and chassis geometry tailored for the unique demands of cross-country events.

Sadly, for UK riders, we won’t be seeing them officially land on UK shores, as the bikes are stated to be landing the USA, Canada, France and New Zealand. That may change at some point in the future, although given that UK GNCC (also known as British Hare and Hounds Enduro) is quite a small series, it may not happen at all.

Triumph’s Paul Stroud said:

“Our motocross and enduro models have already earned podiums in their debut seasons. The TF 250-C and TF 450-C bring that competitive edge to cross country, giving riders machines that are durable, powerful and built for the toughest conditions.”

So, let’s take a closer look at what each machine brings to the party.

Triumph TF 250-C

The smaller of the two models is not short on intent. The TF 250-C is built for riders who want agility and precision over sheer grunt. At its heart is a 250cc single that makes a healthy 46.6bhp at 13,250rpm and 17.5lb ft of torque at 9,000rpm. It revs high, hits hard, yet is said to deliver a smooth spread of power that is designed to shine on technical terrain and through quick transitions.

Like its big brother, the engine features forged aluminium pistons, DelWest titanium valves, and DLC coatings to minimise friction and maximise durability. Magnesium covers save weight while the cooling system should help to ensure that performance stays consistent over long stints.

The chassis follows Triumph’s new off-road philosophy with an aluminium spine and twin cradle design. The KYB suspension, both front and rear, delivers 310mm and 305mm of travel, respectively, with adjustable settings for compression and rebound. Brembo brakes are fitted at both ends with a 260mm front disc and a 220mm rear, while the 18-inch rear wheel helps soak up big hits and keeps traction strong on gnarly trails.

Electronics are not forgotten either. The TF 250-C offers app-controlled engine maps, launch assist, traction control and a quickshifter that works between second and fifth. It all adds up to a package that should give privateer racers a fighting chance of getting onto the podium without needing to spend thousands more on aftermarket upgrades.

Triumph TF 450-C details

If the TF 250-C is about finesse, the TF 450-C is all about stamina and punch. Its 449.5cc single delivers 61.5bhp at 9,500rpm and 36.8 lb ft at 7,000rpm, meaning it is significantly punchier in the mid-range, and stronger at the top of the revs, than its smaller sibling.

It carries the same durability features as the smaller bike, with forged pistons, titanium valves and DLC coatings. The clutch is a steel wet multi-plate unit with hydraulic actuation, designed to take the abuse of long races. And like the TF 250-C, a quickshifter is fitted for clutchless upshifts, allowing riders to focus on the terrain ahead rather than the lever under their left fingers.

Chassis, suspension and brakes mirror the 250, but the rear rim is slightly wider at 2.15in, giving the bigger bike more stability and grip where it needs it. Despite the larger capacity, the wet weight is still just 112.2kg, keeping the 450-C nimble enough to handle tight trails and snotty climbs without feeling like a handful.

Both bikes are available from October 2025, with the TF 250-C priced at US$9,695 and the TF 450-C starting at US$10,695. With Triumph’s dealer network backing them up and a full line of off-road kit available through its partnership with Alpinestars, the brand is serious about its assault on the cross-country world.
