The magazine OVERDRIVE voted the Discover as "Ingenious design of the year" as well as "Bike of the year" in 2005.

The first variant of Discover was launched in 2004. The bike had an engine capacity of 125 cc. A 112 cc variant was launched in December 2005. The bike was claimed to have a mileage of 101 km/l (290 mpg-imp; 240 mpg-US). In 2007, a 135 cc variant was launched.

The Discover was the second Bajaj bike (After the Pulsar segment) to come with the six spoke alloys and the patented "Exhaus-TEC"—basically a resonator that boosts torque at lower rpms. It also employed the Bajaj trademark "DTS-i" Digital Twin Spark Ignition Technology used in the Bajaj Pulsar 150 and 180 DTS-i. At launch, four variants were available:

  • Spoke wheels, Drum brake, Kickstart, Round Headlamp

  • Spoke wheels, Drum brake, Kickstart, Fairing

  • Spoke wheels, Drum brake, Selfstart, Fairing

It was revamped with new graphics, black grab-rail, SNS (Spring in spring) suspension, 130 mm drum brakes, six spoke alloys as standard, selfstart and some engine tweaks predominantly aimed at reducing friction and combustion roar.

A 135 cc model was launched in 2007 which features a front disc brake, self-start, nitrox suspension and black alloy wheels. The silver engine has also been powder-coated black in the 135 cc variant.

A 100 cc version was launched in 2009 with a DTS-Si engine. After the success of the discover 100, Bajaj launched a 150 cc version and stopped production of the 135 cc variant.
