Um guys/girls i could be wrong but when i flicked through the w/shop manual b4 Angel sold the bike too T , the last few sections are a supplement for later models regarding minor changes made up through the years, but 99% of the manual is valid for all zzr250's
re: engine / suspension etc
I also asked about that at Brighton Kawka b4 we ( angel ) bought it, and was told, that except for supplemented model specific section in the back its an all round zzr250 w/shop manual.
That one you looked at probably was the full service manual then. There is two, the Service manual, fat lil thing. Then there is a seprate one entirely called service manual supplement at about half the size.
I have both in almost perfect condition, decided to get them only to decide to get a new bike about 2 months later ...oh well....
