From the leaked snaps, it seems that one is a naked motorcycle equipped with dual-headlight to fit in the Street or Speed Triples line-up, while the other has typical Daytona structure mated with body kits.

Both bikes are powered by a newly and specially developed liquid-cooled, 250cc single-cylinder engine aiming Asian and other progressing markets. It is expected that the bikes will be offered with ABS at least as optional.
Triumph has already set a new production plant in Narasapur, Bangalore, where the company is likely to inexpensively manufacture these two 250cc bikes. If so the firm will also be exporting the same models to other countries at very competitive price tags.

The naked 250cc might be named Street Triple 250R, which will compete directly with KTM Duke 390; while the other, which is guessed to be named Daytona 250R will head against Honda CBR 250R, Kawasaki Ninja 300, and Hyosung GT 250R.
Both the bikes are likely to be hit by 2015 on road.
