The Bajaj Discover 125T Disc is a decent commuter, and some of its owners wanted more from it by way of modifications. Discussion about the possibility of increasing the bike's power, handling or overall performance without sacrificing reliability or voiding the warranty has followed. Topics are common but include air filter upgrades, exhaust modifications, and even more extensive engine work. But there's lots of debate about whether it makes sense to monkey with a bike that’s fundamentally about efficiency and reliability. There are those that believe that any performance gains are minimal and not worth the risk, and there are those that believe there are noticeable improvements. It’s a conversation that tackles the trade off between desired performance and the type of bike you want to ride, and how that could impact resale value and durability down the line. There is also disagreement about legal implications regarding modifications, such as those related to emissions.
