Is this the whole bike or just the coolant tank?

Just the coolant reservoir. The engine and chassis figures in the listing describe the 1990 ZZR600 the part fits, not the item you receive.

Will it fit my ZZR600?

It is intended for the ZZR600 (ZX600) of the early 1990s. Check your model year and part number against the tank before ordering, since later ZX-6R models use different bodywork.

How often should the coolant be changed?

Kawasaki's interval for this era is typically every two years or about 24,000 km. Replace the tank if it is cracked or the plastic has gone brittle.

Why does my tank keep losing coolant?

Usually a cracked neck, a hardened cap seal or a pinched overflow hose. A new tank and cap fixes the first two.

No price is listed here, so there is no current figure to compare. Used tanks from breakers are the low-cost route if condition is good.

Our take on the Kawasaki ZZR600 coolant reservoir

This is the coolant reservoir (overflow tank) for the Kawasaki ZZR600, the 599cc water-cooled inline-four sport bike sold from the early 1990s. The listing's specs describe the whole 1990 ZZR600 — 98 PS at 11,500 rpm, 6.5 kg-m of torque, 195 kg wet, 17-inch wheels and a 530 chain — not the plastic tank itself. The part is a small, inexpensive replacement for a cracked or yellowed original on a 1990s ZZR600. No price was given for this listing, so there is no current figure to compare against its recent range.

What reviewers say

Owners of 1990s ZZR600s treat the coolant reservoir as a wear item: the common complaints are cracks at the filler neck and cloudy plastic that hides the level. Replacements are usually described as fitting without modification.

Pros

Fits the stock mounting point without drilling
Holds coolant level visibly once new
Cheap fix for a slow leak at the neck

Cons

Original tanks crack and yellow with age
Caps can leak if the seal is old
Hard to find new old-stock parts for a 1990 model
