EXCLUSIVE: 350cc Triumph Speed 400 Spotted On Road Before Launch

Quick News Highlights:

• It will still be called the Speed 400

• Engine will have a shorter stoke to be sub-350cc

• Looks identical to the current bike

The upcoming 350cc 2026 Triumph Speed 400 has now been spotted testing on Indian roads ahead of its April 6 launch. While official details are still under wraps, the timing of spotting the test mule strongly hints that it's the new sub-350cc version.

No Design Changes, Same 400 Badge

This Triumph bike looks identical to the current model, with no visible design updates. It continues with the same styling, and unchanged “Speed 400” badge on the side panels. This could have likely been done to save additional costs. 

Engine Downsized With Minimal Changes

The engine will have a shorter stroke and be about 350cc. Core components such as the head and piston are expected to remain the same, while the connecting rod and crankshaft will be revised. This makes the update cost-effective without a full engine redesign. Despite the smaller engine, performance is expected to remain close to the current model.

There could be a slight drop in low-end torque which may affect initial acceleration. The power and torque figures could drop by around 2PS and 2Nm, similar to what has happened with the 350cc Bajaj bikes.

BikeDekho Says

Triumph decided to downsize the bikes as a response to the new GST 2.0 regulations that dropped tax on sub-350cc bikes to 18% and hiked to 40% for bikes above 350cc. The new bike is expected to be priced about Rs 30,000 lower on-road than the 400cc version.
