It’s a very popular thing among Royal Enfield owners to modify their bikes since there is a huge aftermarket scene that offers different performance upgrades and cosmetic enhancements. Air filters to get the Bullet 350X to breathe better, exhaust systems to get a louder thump, and even engine bore kits to increase displacement are all common modifications to Bullet 350X. But there’s a debate going on about whether such modifications improve the bike’s aesthetics or reduce its original character. Excessive and unnecessary changes that accompany upgrades are something purists argue messes wth the original, authentic experience while those arguing otherwise cite the fact that these upgrades are necessary to elevate Bullet's performance to today's standards. It is often a discussion of how to improve rideability while keeping the bike’s classic aesthetics and sound. And also the question of how modifications affect reliability and resale value. Moreover, it is a matter of legal debate among mod enthusiasts concerning certain mods, especially as regards noise levels and emissions of the vehicles.
