It looks similar to the ZRX1200 fan. For that bike, a Suzuki fan is available. KWIK (ZRX US site) has these. Check with him?

It's easy enough to check if it's the fan motor. Just pull the plug from the back of the fan temp switch and use a wire to short between the 2 terminals. With the key on you should hear the fan start up.

I've just had a similar thing happen on my zx6rr, temp gauge in stop-start traffic shoots right up but the fan didn't kick in. Problem is I'd just replaced most of the cooling system and initially everything tested out fine. Funny enough the bike didn't feel particularly hot while I was on it. I'm suspecting either a faulty temp sender to the gauge or the thermostat. Will get back to you once I've solved it.

try testing/replacing the switch first.... they are the usual cause
