Rieju Hard Offroad Water Pump Cover Kit for MR300i (2026) - (Black)

Product Information

Looking to improve cooling performance on your MR300i during demanding off-road riding? This Hard Offroad Water Pump Cover Kit from Rieju is designed to increase coolant circulation while providing durable protection for the engine’s water pump assembly.

The CNC-machined anodized aluminum cover is paired with a high-performance impeller that increases coolant movement through the engine. The redesigned housing adds approximately 5 mm of internal height, helping optimize coolant flow and supporting more consistent operating temperatures during slow, technical riding or extended hard use.

Compared to the standard cover, the aluminum construction offers increased durability and resistance to impacts, abrasion, and heat. The anodized black finish also provides a clean racing appearance that complements the MR300i engine and chassis components.

As part of the Rieju Hard Offroad Power Parts lineup, this kit is engineered specifically for the MR300i platform. Installation is straightforward using factory mounting points and the included hardware, making it a practical upgrade for riders who regularly push their bikes in tough terrain.
