Kaemna Ducati in Germany have one. It's not cheap (in fact it's eye-wateringly expensive at nearly 6K Euros) but all their engines are fully refurbished, serviced and very clean. Takes the guesswork out of buying a 'new' motor rather than one off eBay or from a scrapper where you have no idea of what its history is.
Yeah sure, but then I canīt spend 6 grand on the engine, because you need throttle bodies, exhaust (54+mm), airbox, wiring loom, ecu, mapping and some other bits and bobs.
