Brake disc and pad wear

990 Adventure - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2009 KTM 990 Adventure, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy 990 Adventure should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a 990 Adventure's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the 990 Adventure needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
