One thing Bajaj heavily promotes about the Discover 100M is its Digital Twin Spark ignition (DTS-i) technology, which it says leads to better fuel efficiency and performance. As a result, riders and enthusiasts have been in a conversation for years about whether the technology lives up to the hype, or if it's mostly smoke and mirrors. Some say they experience significant mileage improvement whereas others say they don’t notice much difference from single spark engines. The conversation can often be expanded to compare real world experiences, to dissect the science behind the technology, or to debate its cost effectiveness. This is a complex subject with a myriad of factors affecting perceptions; riding style, maintenance, fuel quality, etc. can all influence how one perceives the character of a particular engine, do to their own experiences.
