Ktm Sm 990
The KTM 990 Supermoto was introduced in 2008 as a street-legal supermoto variant of the adventure-oriented 990 Super Duke/Adventure platform, sharing its LC8 V-twin engine. It was designed to bring aggressive supermoto styling and handling to a larger-displacement machine, bridging the gap between pure track-focused supermotos and road-going performance bikes. Production continued until around 2013, when KTM's focus shifted toward the newer Duke and Adventure lineups, making the 990 SM a relatively rare and sought-after machine among supermoto enthusiasts.

What Buyers Should Know
LC8 Engine Quirks
The 75-degree V-twin LC8 engine is powerful but known for running hot in slow traffic, often causing discomfort for the rider. Ensure the cooling system and thermostat are in good condition before buying.
Watch the Valve Intervals
Valve clearance checks are required every 6,000 miles and are labor-intensive, making them expensive at a dealership. Always ask for service history to confirm these were not skipped by a previous owner.
Strong Resale Value
The SM 990 holds its value well due to its cult following and limited production numbers, making it a smart buy if purchased at the right price. Low-mileage, well-maintained examples are particularly sought after.
