Why Air Filter Care Matters on the RM80

Like most competition motocross bikes, your RM80 operates in harsh, dirty conditions where the filter is often the firstand bestline of defense against engine-damaging dust and grit. Proper filter maintenance can prevent costly engine repairs and keep your bike running at peak performance for years to come.

How Often Should You Service the Air Filter?

Suzuki recommends inspecting and servicing the air filter after every ride in dusty conditions, or at a minimum every two to four hours of use. If you ride in mud or sand, increase the cleaning frequency.
