The guards without a fan are the RG11, and the ones that fit with any fan are the RG16. For the Sherco 250/300 2T 2014–2018 there is the RG05. You can buy the Sherco 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. RG11 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 1.33 kg (with mounts).

The kit includes a SPAL fan with the original Sherco plug, plus bolts and rivets. 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 RG11 guards for both radiators, a SPAL fan with the original Sherco plug, 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.
