A Slider Engine is AC and an Aerox engine is LC!
The other difference is, that the Aerox has his Subframe (Motoraufnahmebuchsen [du weisst schon was ich meine

]) on Top of the engine and the slider in front of the engine.
An other difference is, that the Slider has a cylinder on top of the engine, and the aerox has it in front of the engine
When you want to tune your scoot, you´ll get more performance with an Aerox
