I plan to purchase a new bike soon. I recently read reports that Triumph may launch a Speed 350 model in India around April 2026. Should I buy the Speed 400 now or wait a bit longer for the Speed 350?

Bajaj has decided to downsize the 400cc Triumph and KTM models in India to ensure these bikes attract a lower 18 percent GST in comparison to the 40 percent tax attracted by machines over 350cc in accordance with the government's GST 2.0 regulation. 

The Speed 350 should be very similar in terms of its mechanics to the 400 - save for the smaller engine and slightly lower performance - and will most likely have a more competitive price as well. 

If you don't want to miss out on having a 40hp, 400cc bike, then you should buy the Speed 400 before it is replaced by a slightly smaller machine.
