As a motorcycle enthusiast, we all do like to customize our bikes and the Aprilia RS 150 is no different. It starts with the question of bike modifications and aftermarket upgrades. Riders share the availability of performance parts, cosmetic enhancements and ergonomic modifications for the RS 150. In addition to this, there is a lot of debate on how easy it is to modify them, what effect it has on the warranty, and how much better they perform or look in comparison to other popular 150cc sports bikes. There are those who argue that keeping the bike stock is good for the bike's value, and others who say that personalization is what makes the most of the Aprilia experience.
