This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1975 Honda CB400F (frame CB400F1031181) would be noteworthy even in fully stock form, as these were great machines with a smooth, 10,000+ rpm four-cylinder, precise handling, one of the first production 6-speed gearboxes and some of the most beautiful factory exhaust headers ever fitted to a street bike. Fortunately you can still see those pipes sticking out from the front of its Don Vesco Cafe Royal fairings, and the ad claims extensive cosmetic and mechanical restoration as well, including a full rebuild of the gem-like SOHC four. Find it here on eBay in Powell, Ohio with a $10,500 BIN. Special thanks to BaT reader PGN28 for this submission.

Best Factory Headers: 1975 Honda CB400F w/ Don Vesco Cafe Kit

Though awkwardly angled, over-exposed photos do it few favors, we’re sure this is a killer looking bike in person. Even stock they’re very attractive little bikes, and with a wet weight of just ~395 pounds, sharp handling, a fast-shifting 6-speed and a smooth, responsive 37 hp from a 408cc SOHC, eight-valve four, they were also real standouts in the small-displacment sports/commuter bike market of the era.

Check out the leather pads and low bars, the latter of which are still relatively high compared to the seat, at least by modern sportsbike standards.

Reads the ad: “All new paint, powder coating and chrome. Every single part was cleaned, remanufactured, rebuilt, replaced or painted to new condition. Mechanically the bike is like new with engine being completely rebuilt with pistons, rings, main bearings, gasket, grommets , etc. It starts easily and runs strong. All systems work with new tires, brakes and electrical systems work.”

We just received an update from @RAF, the buyer of the 1975 Ducati 860 GT Mike Hailwood Tribute (link) that sold on BaT on May 2nd, 2019:
“It’s running great. I’m hoping with the new carbs I can kick start it easier in the mornings.

I picked up the bike in person with a sprinter van in New Orleans and drove to San Diego. 
BaT Auction Success Story: Daily Driving a Ducati 860GT
The seller is a great guy and we became instant friends. He has a large collection of vintage cars and bikes. I loved his hot rod early 911 and CITROËN DS. He also had a Ferrari which he listed on BAT but sadly didn’t sell. 
He is a great guy and a true enthusiast. He is an architect and you can tell by his toys that this guy has a good taste. 
I installed the carburetors and new Pirelli tires.
