Industry trend check

Off-road intervals are shortening because modern fuels and high-rev single-cylinders shear oil fast. Synthetic-blend media and verified multipass testing are becoming the baseline; riders are growing suspicious of “no-data” filters. In fact, we’re seeing more buyers ask about ISO 4548-12 efficiency and beta ratios before they click “add to cart.” Good trend, to be honest.

Use cases and rider feedback

    - Weekend enduro on a WR250F: riders report cleaner post-run oil and no gasket seepage.
    - Farm ATV duty on YFM400: stable oil pressure at cold start; surprisingly low debris on cut-open filters after 40 hours.
    - Track day on YZ426F: no bypass spikes in data-logged pressure, even with 10W-50.

Many customers say the fit is “set-and-forget,” which, honestly, is all you want from a filter. Still, always match the OEM code 1UY-13440-01 to your VIN before ordering.
