Front Suspension: Check fork oil level, inspect seals for leaks, adjust preload if equipped.

Rear Suspension: Check shock absorber operation, adjust preload for rider weight/load.

Brakes: Inspect pad thickness, check fluid level, bleed system if spongy, inspect rotors for wear.

Chain: Clean and lubricate regularly, adjust slack to 25-35mm, check sprockets for wear.

Storage and Care

Proper storage procedures for extended periods.

1. Fuel System: Add fuel stabilizer, run engine to circulate, or drain carburetors completely.
2. Battery: Remove and store in cool, dry place, maintain charge with battery tender.
