Radiator guards + fan kit Beta RR 2T 20-23, 4T 20-21 – RG12

• Beta RR 2T: 2020, 2021, 2022, 2023
• Beta RR 4T: 2020, 2021

The kit does not fit the Beta RR 2024 or the 2022 and 2023 four-strokes. The 2022–2023 four-strokes have their own kit: RG12 Fan Set 4T 2022–2023, and the 2024–2026 models the RG19 Fan Set and RG20 Fan Set. The guards without a fan are the RG12. For the same bikes there is also the RG13 Fan Set, with full fronts (1.81 kg against 1.25 kg for this kit with an open frame). You can buy the fan on its own as a separate kit in the “Fan kits” category.

A radiator on an enduro bike is a thin aluminium core with fins. In a fall onto its side the core bends or twists, the channels crack and coolant leaks out. Without coolant the engine overheats quickly, so a punctured radiator usually means a tow back. RG12 wraps each radiator in a frame at the side, and the inner supports brace against the bike's frame and are bolted to it, so the force of an impact goes into the frame. The front stays open, air flows straight onto the core and the factory radiator shrouds stay in place.

We bend the guards from AlMg3 aluminium sheet (EN AW-5754, PA11) 4 mm thick and TIG-weld them. After welding we clean and polish them. It is an alloy with about 3% magnesium, the kind boats are built from because it resists corrosion even in salt water. 4 mm sheet is stiff, holds its shape and stands up well to abrasion. The set with the fan weighs 1.25 kg (with mounts).

The kit includes a SPAL fan with the original Beta plug, a fan holder, a thermal switch that screws into the radiator and complete wiring with a fuse. When you ride slowly in difficult terrain, hardly any air flows through the radiators, and the engine runs at higher revs while you slip the clutch. The coolant boils and escapes through the overflow. The fan pushes air through the radiator even when you are standing still or crawling along. It does not replace a sound cooling system: coolant, cap and tight hoses.

The kit contains the RG12 guards for both radiators, a SPAL fan with the original Beta plug, a fan holder, a thermal switch that screws into the radiator, wiring with a fuse, and bolts and rivets. You bolt the guards to the frame through the inner supports, with no drilling and no changes to the bike.

We design the guards from a 3D scan of the specific bike and cut them on CNC machines in Katowice, Poland. Professional riders test every new model before it goes on sale.
