I recently bought these ones from ebay for a friend and myself:

I got the longer levers on my xtz (then you have to buy the mt-03 version) and a friend got the short one on his xtx. They have a very nice finish and dont look cheap like, with all respect, the alibabaexpress levers. They are a bit on the expensive side but they are all worth it. Very good quality, feels good in de the hand and make your bike look alot better! The seller avdb-moto is a great guy. If you buy more pairs, you can message him so he can arrange for you a nice discount. He has also other colors by the way.
