If you're on standard sprockets then you need a 520 chain with 110 links.
There's a continuous one on Ebay right now!!!
If you don't want to take the entire bike apart just to get the chain on, try
http://www.bargain-biker.co.uk - they do the cheapest chain/sprocket sets around and they're as good quality as anything else!!!
Oh, and you'll be wanting at least and O-Ring chain - if you want the dogs danglies of chains pay a little bit more and buy an X-ring chain
they're supposed to be well-worth it!!!

Bah humbug!!!!
See you again in 15-20,000 miles when i've forgotten everything again lol!!!
Someone must know sprocket sizes??
16/44 rings a bell with me.... Don't take my word for it though!!!! lol:| Most places you order from will be able to tell you your standard chain/sprocket sizes anyway!

have scrubbed up the 2nd hand one and me mates gonna have a look at it, apparently it's only done 2k on the bike it came off so should be good for a year or two
always used DID chains, gold one at that, on the rvf, lasted forever with very little adjustment/cleaning/lubing......... u know what us wimmen are like 
Thanx for the advice, must say somewhere the standard size, could count them on the set I've got but I dont know if that's standard

ok thanx for that, gonna try some sprint racing, will have my first attempt with the set up I've got then if I need to change the gearing I can go from there. Least if I know whats standard I can get the right chain length although will probably be ordering longer chain so I have spare links to swop in or out as I mess about with the gearing
oooooooooooh this is gonna be such fun

I recommend a 14/47 setup which I what I ran on my zxr.....means it will piss over any other 400 (and be a bit light on the font end
) but still top out at about 130mph

ok thanx will keep that in mind, before I start buying stuff will just avago first then take it from there. Big plans for next April when I do flyers @ RAF Woodbridge, completely different gearing required, wanna run a true, timed 140mph minimum! Dunno how fast an unmodified zxr4 engine can go

Will take a little bit to crack 140.
I've got a full beet system with a K&N running @ 63bhp. Mines downgeared to 14/45 and tops out at about 133 but thats at about 14k, optimum power is about 13k so I'm tempted to upgear it again to see what kind of speed I can get then.

well there u go, one down on the front and ur loosing top speed straight away, can take a bit of try n error, dunno what I'll do yet but got 6mths to find out

if u r just using it for sprint racing just go 14 front 47 rear the difference is massive as u dont need top end on a 1/4 mile.
thats what i run and i wont be goin back

Kawasaki's listed top speed for the stock ZXR400 is 143mph.
Obviously if the engine is a bit tired it'll lose a few mph, but otherwise i'd have to say that i believe that top speed.
It's also gonna depend on whether you take your big furry ears off the side of your helmet!

nothing furry on me mate
well see next April, bit of gearing adjustments, 1.5mls of runway to hold it in top to the rev limitor, we'll see what a zxr400 can REALLY do
