Well that is true...
the Indian Alto at the time of launch came in two Versions 796 C.C and 1061 C.C
After sometime the 1061 C.C Version was dropped....
THE REASON for dropping the 1061 c.c version of alto was that it was directly competing with another model... the MARUTI SUZUKI "ZEN"...
The "ZEN" had a 1000 c.c and is still quite popular
the "ZEN" was introduced around 1994..
