Heavy Hitter Gearbox Breather Kit W/Fluid Reservoir

A CNC-machined billet aluminum gearbox breather kit with a baffled internal design and fluid reservoir, built to replace the factory one-way check valve that causes vacuum-related seal damage over time. Designed for e-motos that come from the factory with a check valve that only lets air out not back in creating a vacuum when the gearbox cools that can suck in contaminants or fail seals. Direct mount to factory hose clamp points with no modifications required.

• Direct Fitment: Talaria Sting MX3 / MX4 / MX5
• Universal: Can be adapted to most bikes with breather port

The free-flow design allows proper pressure equalization in both directions, preventing the vacuum buildup that one-way check valves create during cooldown. The baffled breather keeps dirt and water out while the sealed O-ring cap locks everything in place. The fluid reservoir catches oil if the bike tips or crashes. One-way check valves do more harm than good this kit fixes the problem properly.
