Customization culture is huge in India and no bike is spared from the modding craze, and the Yamaha FZS-FI V3.0 is one such popular bike. Many owners have a debate between keeping their FZs stock or jumping into the modification world. Aftermarket exhausts, performance air filters, LED lighting upgrades and cosmetic changes such as a wrap job or painted job including custom paint are all common mods. But, of course, the question is always, do these mods make the bike better or are they just for show? Others say that the FZ comes from the factory perfectly balanced, and that mods can upset this balance, or even void the warranty. Some people argue that just a few choice upgrades can make a huge difference in the riding experience. And then there’s resale value—do mods help or hurt when it’s time to sell? Before we go, let’s hear what FZ owners have to say about keeping it stock or giving it a personal touch.
