Engines
125: KTM LC4c 125, 15 hp (11 kW), 2024 to date
Maintenance
Typical interval: oil change every 7,500 km or 12 months, whichever comes first. Brake fluid every 2 years. On chain-driven models, lubricate and adjust the chain every 500 to 1,000 km. Plugs, valve clearance and air filter depend on the engine: see each version.
Body style and inspection points
On a motorcycle, tyres, final drive and brakes matter as much as the oil change. Check the tyre manufacturing date, steering-head play and fork-tube seals; an oil film on a tube means a fork seal needs replacing. A notched steering bearing can be felt when braking at low speed.
Comparing generations
