Designed in Hinckley, UK, and produced in India, the dynamic duo are both powered by a 398.15cc, liquid-cooled, 4-valve, DOHC, single-cylinder heart capable of 39.5hp (40PS) @ 8,000rpm and 27.7ft-lb @ 6,500rpm.
The motor itself is purportedly part of Triumph’s “TR-series,” which celebrates the brand’s Trophy heritage; featuring Eaton rocker arms (or a finger-follower valvetrain) with a low reciprocating mass, the power train works through a six-speed gearbox and is nestled inside a tubular steel chassis, complete with a bolt-on rear subframe.
A modest front radiator and high-and-happy pipe system accompany disc brake stopping power, with floating duties carried out via a 43mm ‘Big Piston’ inverted fork complete with a gas-charged rear mono-shock.
By the way, both bikes feature the same LED lighting, as well as identical 17” rear cast aluminum alloy wheels and a nice 13-liter fuel tank.
For electronics, each bike makes use of the following:
Switchable traction control
Competition for both the Speed 400 and Scrambler 400 X include the KTM 390 Duke and BMW G 310 R (in select markets), with the official debut to dealerships happening in January of 2024.
