AutoKarnet advice
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.
AutoKarnet advice
Other documented generations of this model: • GSX-S1000 (2021) (from 2021) : naked bike, 152–152 hp. A first registration near a generation change does not identify the car on its own: check the body style and powertrain before using a service schedule.

Replace the fluid in both circuits (and the hydraulic clutch if fitted), whatever the mileage; dark fluid has absorbed moisture.

Fork oil change and seal check; an oil film on the tubes means a seal needs replacing before it contaminates the brake caliper.

Lubricate and check the tension every 500 to 1,000 km and after rain; replace chain and sprockets together when the chain no longer holds its tension or the teeth are hooked.

Replace the full set; worn plugs raise consumption and cause misfires.

Replace more often in dusty conditions.

Check and adjust if needed, often together with the plugs; too little clearance burns the valves, too much makes the engine noisy.

Replace the coolant and check the hoses and radiator; check the level cold between services.
