Press ratings
Remarkable chassis and suspension for the price, punchy engine, finish worthy of far more expensive Triumphs; slightly jerky throttle in town, slightly cramped legs.
Triumph quality at an aggressive price, engine best kept between 5,000 and 8,000 rpm; strong vibration from 7,000 rpm, annoying on the motorway.
Lively engine with a strong midrange, responsive chassis, good finish and attractive price; slightly delayed throttle response.
Superb looks, characterful engine, well-balanced chassis, careful finish; hard-to-read rev counter, slightly soft suspension, harsh shock over big hits.
Press synthesis
What the world’s press says
The Speed 400 scores 5/5 from MCN and BikeSocial, 85.75/100 from Motorcycle.com and 14.9/20 from Caradisiac. Cycle World, RevZilla, 1000PS and Le Repaire des Motards tested it without a numeric score. All tests cover the 2024 model year, technically identical to the current bike.
What reviewers like: a finish worthy of far more expensive Triumphs, first-rate chassis and brakes, a lively engine, A2 compliance and value for money considered unbeatable in the class.
What they criticise: a busy engine and vibration on the motorway, throttle response that could be better at low speed, compact dimensions and instruments without connectivity.
Key quotes
"The Triumph Speed 400 transcends the A2 licence category and its modest 398cc capacity to be a well performing, premium machine, and all for under £5000."
"Otherwise the Speed 400 is an absolute gem. Right now it's easily the best new bike you can buy for less than £5000. It's not just a great bike for A2-licence riders, it's a great bike full stop."
"This is one of the greats in entry-level motorcycling; hell, it's one of the great motorcycles of 2024. Handling is far better than it should be for a $4,995 motorcycle, the engine is punchy and fun, the ergos are comfortable, and you won't get tired of looking at it."
"Attractive in looks, surprisingly effective and convincing in performance, the Triumph Speed 400 is a sparkling surprise."
"Not content with shaking up expectations, the new Triumph Speed 400 establishes itself as an excellent small motorcycle offered at a knockout price."

Our review
What is the 2027 model year?
Launched in early 2024, the Speed 400 is Triumph’s first single-cylinder road bike, on a platform developed with Bajaj. It has not changed technically since: the 2026 and 2027 model years only brought new colours, including the Racing Red / Pewter Grey offered since August 2026. Triumph France’s website now states Euro 5+ homologation. The 349 cc Indian version is not sold in France.
How much does it cost?
Triumph France lists the Speed 400 at €5,945 in Phantom Black / Storm Grey and €6,045 in the Pearl Metallic White / Phantom Black and Racing Red / Pewter Grey colours. In the United States it costs $5,495.
How good is the engine?
The 398 cc liquid-cooled single makes 40 hp (29.4 kW) at 8,000 rpm and 37.5 Nm at 6,500 rpm. Below the 35 kW limit, the Speed 400 is A2-compliant without restriction.
Cycle World finds it punchy and fun, 1000PS lively with a strong midrange. Its limits show on the motorway: short gearing and a busy engine (MCN, BikeSocial), vibration from 6,000 to 7,000 rpm (Motorcycle.com, RevZilla). At low speed, BikeSocial and Cycle World find the throttle a little abrupt, and 1000PS its response slightly delayed.
How does it ride?
This is its strong point: MCN calls its finish and chassis sublime, BikeSocial praises impressive suspension, brakes and handling, and Cycle World handling far better than expected at this price. Motorcycle.com finds it super agile around town and on mountain roads.
The reservations concern:
- compact dimensions, which Motorcycle.com likens to a 3/4-scale bike and Caradisiac finds small;
- slightly soft suspension and a shock that is harsh over big hits (Le Repaire des Motards);
- a seat that gets a little firm after a few hours (MCN);
- a hard-to-read rev counter (Le Repaire des Motards) and instruments with no connectivity (BikeSocial).

Triumph quotes 3.5 L/100 km, giving a range of about 370 km from the 13-litre tank. 1000PS recorded 3.6 L/100 km during its test.
