To be a little more specific, your Bullet 50 has a GY6 engine and CVT tranny, compared to the Cub motor and gearbox tranny of the Grom.
-Its still a good looking ride. The styling is a huge improvement over the older Roma.
-Plenty of speed parts and other accessories are available for the GY6 mill and CVT.
