Why are they expensive on the 848?
Machine time / set up and the programing. But if done in the right window the actual cost is very cheap.because it's Sato...everything Sato is expensive. And because of supply and demand. It's not a product that they sell in the thousands, so they have to make a relatively small amount and machining is very expensive unless you mass-produce something.
A few years ago I designed my own open clutch cover just because I wanted something different....when I gave the drawings to a local machine shop that I work with a lot, they quoted me somewhere in the $900. Sure enough I bought an EVR from DO for like $120 lol. Just for curiosity I asked the owner of the machine shop how much it would be if I were to order 500 of them. He told me it would be closer to $200/each. So yeah...the more you make, the cheaper shit gets. Also one of the reason Ducatis are overall more expensive than Hondas, Yamahas, etc.
