HiFlo HF655 Filter 770.38.005.001 – High-Flow for KTM

If you ride or wrench on KTM singles and the Husaberg/Husqvarna cousins, you already know oil is the lifeblood. The filter? That’s the gatekeeper. I’ve been testing a lot of cartridge filters lately, and the Hi Flo H F655 Oil Filter KT M 770.38.005.001 - Husabe Rg Husqva Rna KTM 250/450/500/690 keeps popping up in rider chats and dealer counters. Built for KTM 250/450/500/690 platforms (and compatible Husaberg/Husqvarna models), it’s positioned as a dependable, no-drama service part. To be honest, that’s exactly what most of us want.

What’s changing in motorcycle filtration

Industry-wide, we’re seeing a shift toward tighter, more consistent media—often blended cellulose/synthetic—to balance flow at cold starts with finer capture at operating temp. Off-road thumpers are particularly hard on filters thanks to dust ingestion and frequent clutch contamination. It seems that riders want “OEM-like fit, slightly better efficiency, and readily available.” That’s where Hi Flo H F655 Oil Filter KT M 770.38.005.001 - Husabe Rg Husqva Rna KTM 250/450/500/690 aims to land.
