Motorcycles
The motor officers in "CHiPs" ride Kawasaki KZ-900P and KZ-1000P motorcycles. Ponch almost won the street model (a 1978 Kawasaki Z1-R) on a game show in "Name Your Price".
This is a picture of the KZ-900P, it's used in season one and season two.
The KZ-1000P was used from season 3. It has a different windscreen, other front fender, smaller pursuit lights and other (small) changes.
They used the same trailer from season 3 as they did in the first two seasons. The bikes on the trailers were KZ-900P and those had the big pursuit lights and other windscreen. Because the difference would be visible, they "reengineered" the KZ900. They removed the KZ900-P windscreen and put a KZ1000-P windscreen on the bikes. They forgot to replace the pursuit lights (they are still the KZ900 lights), so they are much bigger than the lights which are on the KZ1000. Also, the metal frame below the headlight is missing on the KZ900.
Erik Estrada owns one of the KZ-1000P bikes which was used in the series. Note that the engine was taken out.
