Hiflofiltro
Hiflofiltro makes motorcycle filters. Autotools carries Hiflofiltro air and oil filters for a wide range of motorcycles and scooters.
Hiflofiltro covers the core of bike servicing: HFA air filters and HF oil filters, for models such as the Honda SH125 and SH150 or the BMW R1100 GS.
Find the right filter by model, engine size and year, which many listings carry in the name. If you know the original filter number, search by that. Change the oil filter with every oil change and check the air filter at the start of the season.
