Suzuki RM-Z450 Maintenance Schedule
The Suzuki RM-Z450 is Suzuki's 450cc 4-stroke motocross bike. Suzuki writes its maintenance chart in races and hours, and this page lists every interval from the official RM-Z450 owner's manual.

How The Suzuki Schedule Works
Suzuki's RM-Z maintenance chart is written for racing. Its three columns are every race (every 2 hours), every 3 races (every 6 hours) and every 6 races (every 12 hours), and each item is coded inspect, clean, replace, tighten or lubricate. Coolant, radiator hoses, brake hoses and brake fluid are on a yearly replacement schedule, and a separate lubrication table covers bearings and pivots by number of races.
The manuals we used do not print a model year. They are the current Suzuki owner's manuals published on Suzuki Australia's official site, so confirm the edition matches your bike.

Ownership Notes
Suzuki's chart is aggressive by design: engine oil every 3 races (about 6 hours), the oil filter every 6 races (about 12 hours), and a new piston and rings every 6 races. Those are race intervals, written for a motocross bike that gets raced, and Suzuki counts them in races and hours, not calendar time.
The manual recommends SAE 10W-40 JASO MA oil, with 1,050 ml for an oil change and 1,100 ml with a filter change. It also calls for a new silencer packing every 6 races and after a race in sand.
