RD400 / RD350 / RD250 / R5 Filters
Your vintage RD350 needs air as badly as you do. Running that screaming 2-stroke engine on a dirty air filter is like breathing under water: a bad idea. Our 42mm performance pod air filters are a perfect solution to your air flow issues. Simply remove your RD250, RD350 or RD400 stock air filter and box, and replace with this no-nonsense air filter. You’ll be back up and running in no time, and you’ll feel the hit of the power band these 2-stroke Yamahas are famous for.
