Reiju is an emerging brand dedicated to small-to-mid capacity adventure bikes, aimed at riders approaching off-road touring on a contained budget.
The P08 technology from Sprintfilter forms the core of the solution: a dual-layer polyurethane foam media with three-dimensional structure that traps particles as small as 50 microns while maintaining air permeability superior to stock filters. The payoff is immediate: increased torque at lower revs, livelier throttle response, and engine protection that makes no compromise.
Riders pursuing even more extreme performance on heavily modified machines can step up to the racing air filter P08F1-85, featuring an additional filter layer and stainless steel mesh that captures even finer particles (not street-legal for standard use). Alternatively, the waterproof air filter P037 delivers ultrafine filtration to 37 microns in demanding, muddy conditions without sacrificing airflow.
All Sprintfilter air filters are washable and reusable: rather than replacing your filter seasonally, clean and regenerate it dozens of times while maintaining original performance.
Installation is straightforward: Sprintfilter filters for Reiju mount into the original airbox without any mechanical modification, certified for street use. Your Aventura Rally 307 returns to the road within minutes with superior breathing power.
