What mods are the absolute musts for a KTM 990 Adventure?

As with any KTM 990 Adventure, owners like to modify their bikes, and some want to make it faster, others want to make it more comfortable, and still others want to make it more versatile. Everything from minor ergonomic changes to huge performance improvements is within reach. Suspension upgrades, exhaust systems, fuel management, and off-road protection parts are common areas for modification. Other topics discussed are comfort mods such as seats, windscreens, and handlebar risers. A few riders are attempting to boost power output, others are trying to improve reliability, and some are looking for the long-distance touring capabilities. Modifications are often chosen based on the use the rider intends to get out of the bike, whether that's more off-road use, long-distance touring, or a combination of both. This typically brings about debates about which mods provide the best bang for your buck and which are possibly must-have mods to get the most out of the 990 Adventure.
