MAICO GS 504

The GS 504 is a four-stroke enduro tool with a Rotax heart. Trail-ready, but it punishes neglect. Stay on top of valve clearances and oil filter swaps — that's the baseline. Inspect the timing belt and tensioners regularly; let one go mid-race and the top end is scrap. We stock the four-stroke service parts that keep it honest.
