Maintenance About engine overhaul of CBX1000...
The popularity was split between the 70s and 80s, and currently the Z series has a larger market share, but I'll write about the differences. The main difference between the CB-F and Z series engines is the number of valves. The Z series has two valves, while the CB-F series has four. Putting aside the things that are not immediately accessible or visible, such as a strong engine or powerful output, it all comes down to this one point.
