We were promised these enduro bikes when the motocrossers were introduced, and now they’re here—the 2025 Triumph TF 450-E and TF 250-E. Rather than being entirely new designs, the Triumph enduro bikes are heavily based on the motocross bike, though with many of the features you would expect for off-road riding. We’ll break this up into three parts:
Differences Between the Enduro (TF 250-E and TF 450-E) and Motocross (TF 250-X and TF 450-RC) Bikes
- The enduro motors have more inertia than their motocross counterparts. This means a more stable, tractable power delivery suited for diverse enduro conditions, compared to the motocross engines, which are optimized for peak performance on closed courses. California buyers will want to know that these are competition models and not Green Sticker legal.
- The Athena-sourced electronics package is specific to the enduro motors. There are two enduro-focused engine maps, which can be swapped on the fly. If you spring for the Wi-Fi module and Triumph MX Tune Pro smartphone app, you can download custom tunes. The traction control is calibrated for off-road conditions.
- The KYB suspension has shorter travel and different settings on the enduro bikes than the motocrossers. The TF 250-E and TF 450-E shorten the travel by 0.4 inches compared to the motocross models, and the shock linkage is three-position adjustable. The settings are adjusted for better bump absorption and reduced pitch during cornering on rugged trails versus motocross tracks. Also, the swingarm geometry is specific to the enduro models, with a focus on agility.
- The enduro bikes get off-road de rigueur 18-inch rear wheels, compared to the 19-incher on the MX bikes. I.D DirtStar 7000 rims are laced to machined cast-aluminum hubs. Instead of motocross tires, the enduros get FIM-friendly Michelin Enduro 2 tires.
- The ergonomics of the enduro models are designed for longer rides. The TF 250-E and TF 450-E prioritize rider comfort for prolonged riding with a non-slip Pyramid seat cover and durable, high-quality foam padding.
- Yes, those are lights on the 2025 Triumph enduro bikes. The beam is projected from LEDs.
- The fuel capacity of the enduros is increased to 2.2 gallons. That gives the bike an extended range for off-road racing.
- Handguards are part of the package. They’ll keep rocks and branches at bay.
- A digital dash is standard. You’ll find speed, gear position, engine temperature, and more on it.
Common Features of the TF 250-E and TF 450-E Enduro Bikes
- The 2025 Triumph TF 450-E and TF 250-E share the same frame. It’s an aluminum spine frame, rather than the Japanese-style twin spar or Euro steel frame.
- Although valved differently and having shorter travel, the enduro bikes’ KYB units are the same as those used on the MX bikes.
- The upshift-only quickshifter works between 2nd and 6th gears. You can turn it off if you like, though we don’t know why you would.
- Plenty of high-end components are shared by the TF 450-E and TF 250-E. Both feature Galfer discs with Brembo calipers for braking, a ProTaper ACF Carbon Core handlebar, ODI half-waffle grips, magnesium engine covers, and bodywork with Triumph Performance Yellow, Black, and White graphics.
Differences Between the 2025 Triumph TF 450-E and TF 250-E Enduro Bikes
- The motors have the same differences they have in the motocross versions. In addition to the displacement and power output being different, the TF 450-E includes Diamond Like Carbon (DLC) coatings on the gudgeon pin and rockers for improved durability and reduced friction, a feature not mentioned for the TF 250-E. Also, the TF 450-E features a side-resonator in the muffler for a deep exhaust tone. In contrast, the TF 250-E has a lightweight stainless steel exhaust with an integrated Helmholtz resonator in the header pipe for enhanced performance. An Akrapovič muffler is optional.
- Triumph intends the enduros for different riders. The TF 450-E is tailored for experienced riders seeking power, speed, and versatility on open trails and hills, while the TF 250-E is intended for riders wanting responsive, manageable power for technical challenges and a high-revving motor.
- The list price of the 2025 Triumph TF 450-E is $1000 more than the TF 250-E. The price tag on the TF 450-E at your local Triumph Off-Road dealer will read $10,795.
You can order the 2025 Triumph enduro bikes now, but they won’t be arriving until June. The stock color is Triumph Performance Yellow, and there’s an accessory graphics kit for the radiator shrouds.
