With increasing competition from other bikes in 125cc segment, Bajaj has unveilled a new version of their mid end bike model - Discover.
I personally feel their 112cc Discover didn't get much popularity, but I am certainly seeing many many 135cc Discovers on road.
The price is around 55k compared to around 50k for the 125cc model. New 135 cc Discover comes with fully black engine casing and alloy wheels.
