Triumph’s Sub-350cc Speed T4 Spied in India Ahead of April Launch

To tap India’s lower tax slab for 350cc-and-under bikes, Bajaj and Triumph are expected to downsize existing 400cc engines to cut prices by roughly Rs 20,000.

Overview

  • Bajaj has officially scheduled the launch window for new Triumph 350cc motorcycles in April 2026.
  • A Speed T4 test mule was photographed on Indian roads, appearing visually unchanged and pointing to updates under the tank.
  • Reporting indicates the current 399–400 cc single will likely be reworked to just under 350 cc through internal changes such as bore, compression and ECU mapping, with chassis and brakes carried over.
  • Analysts expect a modest drop in peak output to about 34–35 hp, with the overall riding character projected to remain similar.
  • Price estimates suggest the Speed T4 could start near Rs 1.75 lakh ex-showroom—around Rs 20,000 lower—with the same downsizing approach likely to extend to select Bajaj and KTM 400cc models.
