The short version
The Speed 400 undercuts everything with a badge on it and still feels premium: quality paint, a torquey 398 cc single and 16,000 km service intervals. It trades outright pace and electronics for polish and running costs, which is exactly what many A2 buyers want.
Where it wins
- Cheapest route into the A2 naked class from a major brand
- 16,000 km service intervals halve scheduled maintenance visits
- Accessible 790 mm seat and friendly power delivery
Where it loses
- 40 hp trails the KTM and Husqvarna singles
- No TFT, ride modes or quickshifter at any price

Premium feel at the cheapest price in the class
The Speed 400 is built by Bajaj in India to a Triumph design brief, and the reviews all trip over the same surprise: the cheapest bike in the class feels like the expensive one in the car park. Testers repeatedly single out the paint, switchgear and finishing as outstanding for the money, and owners a couple of thousand miles in report the shine has not worn off.
The single is tuned for the torque you use daily rather than the revs you visit on special occasions, and road testers describe it as pure joy on backroads: not fast, not slow, just pleasant in a way spec sheets cannot record.
What 5,745 EUR gets you, and what it does not
You get a proper radial brake, traction control, a 790 mm seat that fits nearly everyone and build quality that photographs like twice the money. You do not get a TFT, ride modes or a quickshifter at any price, and the ABS is the basic sort.
The one recurring dynamic complaint in owner threads is vibration at sustained motorway pace, where the short gearing has the single spinning hard at 110 km/h. Owners fit a one-tooth-larger front sprocket and report most of it disappears, which is the cheapest fix in this database.
The service interval nobody matches
Services every 16,000 km with valve checks at 32,000 halve the workshop visits of the KTM group singles, and about 370 km of range covers a week of commuting. Running costs are the quiet headline of the whole package, and the reviews increasingly lead with them.
Against the 390 Duke you give up 5 hp, the electronics suite and some chassis edge, and you keep 550 EUR plus years of cheaper servicing. For a first bike or an honest commuter, that trade wins more often than my scorecard would like to admit.
