Race Radiator Guard by Evotech Performance

Here is what our staff has to say about this Yamaha R9 radiator guard.

• Strong protection against debris: The guard is CNC-machined from aircraft-quality aluminum and uses a hexagonal matrix-pattern grille. This kind of design — as the maker describes — helps defend the radiator against stones, grit, road debris, and flying bits of rock that might otherwise puncture or damage the radiator’s thin cooling fins or internal coolant pathways.
• Maintains airflow and cooling efficiency: A big concern with radiator guards is blocking airflow and degrading cooling. Because this guard’s hole pattern is optimized for airflow, it offers protection without impairing cooling performance — a balance that cheaper guards often fail at.
• Race-ready, lightweight, and well-finished: The guard is described as “race” quality, intended even for track or aggressive road use (like gravel, stone-lined, or debris-rich roads) — but remains lightweight thanks to aluminum construction. The powder-coated finish also suggests durability and corrosion resistance over time.
• Easy bolt-on installation: It reportedly uses existing mounting points on the bike — no drilling or major modifications needed — which simplifies installation and keeps things clean if you want to remove or swap it later.
• The Race Radiator Guard by Evotech Performance is an excellent upgrade for riders who push their bikes hard — whether on gravel roads, rural routes with loose rocks, or track/spirited city riding where debris and road-hazards might otherwise damage the radiator. It’s also a smart pick if you want long-term peace of mind and want to avoid costly radiator repair or replacement.

  If you mostly ride on clean pavement and rarely push conditions, it may not feel essential — but even then it’s a relatively low-weight, low-maintenance insurance policy.
