I also have an R6 master cylinder. It was freshly rebuilt and powder coated. It was cracked where the handle bolts in so I had it welded. Handle will still fit just as snug as stock and is still 100% safe. The MC actually worked with the cracked part before it was welded. Comes with the reservoir. It does need a lever
$60 shipped.
If you want to buy both for a kit, $125 shipped.
