The launch of the two models, made in partnership with UK's Triumph Motorcycles, sent Bajaj Auto shares to a record high of 4,900 rupees.
The Triumph Speed 400 will be priced at 233,000 rupees ($2,834), Bajaj Auto said, but did not disclose a price for the Scrambler 400X.
Bajaj will oversee the production and distribution of these bikes as part of the partnership, the two companies had said in April.
With the entry of Bajaj and Hero in the premium bike space, analysts see stiff competition, loss of market share and growth concerns for Eicher.
Hero MotoCorp's shares closed up 4.2%, nearly matching their 4.5% jump on Tuesday, while Bajaj Auto's shares have gained roughly 6% in the past two days.
