In its last years the Chetak 150 was the tail end of a scooter that had once sold around 100,000 units a month and carried waiting lists in India. Bajaj eventually announced it was leaving scooters to concentrate on motorcycles, as buyers had moved to bikes. The two-stroke 150 kept 10-inch wheels, drum brakes and an automatic belt drive.
