Radiator Guard Grille For Triumph Street Triple 660 / 765 - 2020 to 2027

Radiator Guard Grille for Triumph Street Triple 660 and Street Triple 765 (2020 to 2027)

The Triumph Street Triple family uses a compact, forward-mounted radiator that sits exposed at the front of the engine bay between the frame tubes. The radiator fins have no dedicated protection in the stock configuration - road debris thrown from the front tire, stone chips from motorway traffic, and insects at speed all hit the cooling fins directly. A bent or kinked fin row reduces coolant flow efficiency, and a harder impact can puncture the core and cause an immediate coolant loss. This radiator guard grille mounts in front of the radiator on the Street Triple 660 and Street Triple 765, intercepting debris before it reaches the fins while maintaining full airflow through the cooling system.

The guard is fabricated from stainless steel mesh welded into a formed steel mounting frame, finished in black powder coat. It mounts using the factory radiator bracket bolt positions on the Street Triple - a direct bolt-on installation that requires no drilling, no modification to the cooling system, and no additional hardware beyond the supplied fasteners. The mesh aperture is sized to block fragments while maintaining approximately 85% of the unobstructed airflow the radiator receives at speed. The black finish integrates cleanly with the Street Triple's dark engine bay and lower frame section across all variants and color schemes.

At this price point, the guard is cost-effective protection for a component that takes direct exposure every ride. The Street Triple is used heavily as an urban commuter and track day machine - both environments where road debris and stone impact are consistent hazards. Replacing a damaged radiator core on the Street Triple platform requires sourcing a Triumph-specific part that can involve significant lead time; preventing the damage with a bolt-on guard costs a fraction of the repair.

Confirmed fitment for the Triumph Street Triple 660 (2023 to 2027) and Street Triple 765 S, 765 R, and 765 RS (2020 to 2027). The Street Triple 660 uses the 660cc parallel twin introduced for the entry S variant, while the 765 variants use the 765cc inline triple. Both share compatible radiator mounting bracket geometry for this guard. Also fits the Street Triple Moto2 Edition where the stock radiator bracket positions are retained.

Frequently Asked Questions

Does it fit both the 660cc and 765cc Street Triple without modification?

Yes. The Street Triple 660 and Street Triple 765 share the same radiator mounting bracket positions and radiator core dimensions, despite using different engine configurations. The guard covers both platforms with the same part and the same installation procedure. No adapters or additional brackets are required for either variant.

Does the mesh reduce cooling effectiveness at low speed or in traffic?

The Street Triple's cooling fan activates when coolant temperature rises at low speed and in traffic - the fan operates on the engine side of the radiator and is not affected by the guard. At speed, the mesh reduces incoming airflow by approximately 10 to 15% compared to an unguarded radiator. The Street Triple's cooling system is designed with thermal margins that comfortably accommodate this reduction. No overheating issues have been reported by verified buyers running this guard in summer urban riding conditions.
