This genuine OEM Aprilia coolant expansion tank, also known as the radiator overflow bottle, is designed to manage coolant expansion and overflow as the engine reaches operating temperature. Constructed from durable semi-translucent polypropylene plastic, the reservoir allows easy visual checking of the coolant level. It includes the original twist-on sealing cap and upper vibration-dampening rubber strip for secure factory-style installation. Compatible Models • Aprilia RS 125 Extrema – 1992 to 1994 • Aprilia RS 125 Replica – 1992 to 1995 • Aprilia RS 125 Sport Production / SP – 1992 to 1995 Designed for early-generation Aprilia RS 125 models using the original two-stroke cooling-system configuration. Please compare the mounting tabs, reservoir shape, and hose outlet positions with your original part before purchase, as later RS 125 models may use a different expansion tank design.
Please verify compatibility with your specific motorcycle model before purchasing.
