Do I need to break in the clutch after replacing it?

Always perform the break in of the clutch.
Only about 30% of the friction surface of the new clutch is in contact. The performance of clutch is exercised only when 100% of the friction surface is in contact.
It depends on the condition it is used, but drive for about 500 km in the urban condition to break in the clutch.
Repeat the starting with under 3000 RPM to break in the clutch.
Frequency of the clutch operation and load is too low in the highway driving or changing the gears, and break in of the clutch will not take place.
The point to make the clutch last is to break it in properly.
