Recent spy shots confirm that Triumph’s upcoming cafe racer, based on the Speed 400 platform, will be called the Thruxton 400. While the official launch is expected later this week, multiple sightings of test mules in recent weeks have offered a clear picture of what to expect. Based on what we know so far, here are the key differences between the Thruxton 400 and the Speed 400 it’s derived from.
Triumph Thruxton 400 vs Speed 400: Design and styling
The most notable differences between the Triumph Thruxton 400 and the Speed 400 are in their styling. Staying true to the Thruxton line, the former features classic cafe racer elements such as a distinctive half fairing, clip-on handlebars, bar-end mirrors, and a single-seat setup with a rear cowl. The fuel tank design has also been subtly revised to appear sharper and more aggressive. The remote brake reservoir also seems to be new, reminiscent of larger European motorcycles.

The spy shots also reveal that the Thruxton 400 will feature a dual-tone paint scheme, with a red and silver combination confirmed as one of the options.
Other changes include a redesigned tail-light and what appears to be a blacked-out USD fork on the Thruxton, compared to the gold-colored unit on the Speed 400. However, this change appears to be purely cosmetic, and the underpinnings on the two will likely be the same.
Triumph Thruxton 400 vs Speed 400: Chassis and ergonomics
The styling changes go beyond just visual appeal. The Thruxton’s lower-set clip-on handlebars position the rider in a more committed, forward-leaning stance. In contrast, the Speed 400’s more conventionally placed handlebars enable a relaxed, upright riding posture.
Both the Thruxton 400 and Speed 400 appear to share the same chassis, including the frame, USD front fork, and rear monoshock. They ride on 17-inch alloy wheels and are equipped with disc brakes paired with dual-channel ABS. However, there seems to be a difference in tyre choice. While the Speed 400 now ships with Vredestein rubber, the Thruxton 400 looks like it will come fitted with MRF tyres, similar to the Speed T4.
Triumph Thruxton 400 vs Speed 400: Price
Traditionally, the Thruxton models have been priced higher than their Speed counterparts in the company’s larger-capacity lineup and it’s reasonable to expect a similar pricing strategy with these offerings. That said, the manufacturer seems to have incorporated some cost-saving measures on the Thruxton 400, like a simpler tail light design and the omission of adjustable levers found on the Speed 400. An official launch is expected later this week, and this story will be updated with detailed specifications and pricing once available.
