BETA ARK 50 AC

Ark 50 AC. Paddock runabout, air-cooled, built for laps round the truck and trips to scrutineering. Simple mill, simple jobs. Stay on top of the brakes. Pads wear faster than you think when you're crawling through a packed paddock. Service the cables, keep the chain fed, swap fluids before they go dark. Filter by category, brand or price to pull what fits.
