A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
Cheap chinese copy:
Motorcycle Starter Solenoid Relay for Kawasaki ZR ZX VN BN EX Honda CBR600RR NEW | eBay
or look for OEM relay.
But I suggest to get exactly the used OEM relay from Kawasaki - it will not fail you anymore. item number 281703702797 or similar
I've already seen this when me and my friend bought two shad seats. One of them had the similar damage, we repaired it in local shop, sent the proofs and got a patrial refund (for parts and labor done).
I tried both. 7000km on cheaper ones, and a few kilometers on newer improved. I vote for new improved version. They are more comfortable than stock and more adjustable.
Well, I got the first batch of cheap clips. They are pretty close to honda, but they look and feel cheap. Also plastic look a bit different. Not road tested them yet, but the sizes are correct, locking and unlocking works the same way. I think it is safe to use them in some non-critical places.
