KZ400 Performance data.

Sourche: Classic Motorcycle Mechanichs

This is the KZ400 perfromance data from tests done in UK in the 70's:

1975 D:

Standing start 1/4 mile : 16.40 sec / 80.81 mph
Acclereation:
110 yards 6.00 sec / 53.6 mph
220 yards 9.90 " / 66.7 "
330 yards 13,40 " / 73,4 "

Mean top speed 95.41 mph
Best one-way 103.69 "
Mean normally seated na

And the figures for the 1978 B1:

Standing start 1/4 mile : 16.05 sec / 81.96 mph
Acclereation:
110 yards 6.2 " / 53.90 "
220 yards 9.9 " / 68.40 "
330 yards 13,1 " / 76,70 "

Mean top speed 97.65 mph
Best one-way 102.40 "
Mean normally seated 85.90 "

There is one interesting thing about these tests, and that goes for every test I have read, and for every bike that was tested in that period. The top speed will increase with at least 10 mph or more when the riders is riding flat out. Some bikes will have a difference of almoast 15 mph!
