To break in your Ducati Streetfighter V4 2021, keep the engine speed below 5,500 RPM for the first 1,000 km (621 miles). Vary the engine speed and avoid prolonged periods at constant RPM. After this period, gradually increase the RPM.
The recommended tire pressure for the Ducati Streetfighter V4 2021 is 2.5 bar (36 psi) for the front tire and 2.9 bar (42 psi) for the rear tire when riding solo. Adjust accordingly if carrying a passenger.
It is recommended to change the engine oil every 12,000 miles (20,000 km) or 12 months, whichever comes first. However, the first oil change should be performed at 1,000 km (621 miles) as part of the break-in maintenance.
Ducati recommends using a fully synthetic 15W-50 engine oil that meets or exceeds API SJ and JASO MA2 standards for the Streetfighter V4 2021.
To adjust the suspension on your Ducati Streetfighter V4 2021, use the adjusters located on the forks for compression and rebound. The rear shock can be adjusted for preload, compression, and rebound. Refer to the owner's manual for detailed settings based on your riding style.
If your Streetfighter V4 2021 won't start, check the battery charge, ensure the kill switch is in the 'run' position, verify that the side stand is up, and the bike is in neutral. If the issue persists, consult a Ducati dealer.
To adjust the chain tension, place the bike on a rear stand, loosen the rear axle nut, and use the adjuster bolts on each side of the swingarm to achieve the correct slack. The proper slack is between 30-32 mm. Tighten the axle nut to the specified torque.
Before storing the bike for winter, clean it thoroughly, change the oil and filter, fill the fuel tank and add a fuel stabilizer, inflate the tires to the recommended pressure, and disconnect the battery or connect it to a trickle charger.
To reset the service light, you typically need to connect the bike to a diagnostic tool such as the Ducati DDS. It's recommended to have this done by an authorized Ducati service center following a completed service.
Valve clearance checks are recommended every 24,000 km (15,000 miles) for the Ducati Streetfighter V4 2021. Ensure that this maintenance is performed by a qualified technician.
