eBay Find of the Day: Why this motorcycle's a deal at $135k

There can be no doubt that Soichiro Honda left a lasting legacy by lending his engineering talents to the company that bears his name. This can be said particularly of motorcycles, and the company outdid itself when it introduced the 1969 CB750. Widely considered the world's first superbike, it combined a then-powerful 67-horsepower, 736cc, inline four-cylinder engine and cutting edge tech for motorcycles at the time like an electric start and front disc brake. It is simply one of the most important motorcycles ever made, and now one of four handmade prototypes is up for auction on eBay Motors.
According to the seller, Honda had an idea that it had something special with the CB750 and built four preproduction models to be shown off to American media in 1968. Each one was hand-built by Honda technicians from bespoke components, and this blue/green model was photographed by magazines and for promotional material at the time. The seller believes that one of the four prototypes was destroyed, one is in Europe and one is unknown, which means this may be the only chance for collectors to get their hands on one.
The bike has prompted quite a bidding war with 97 bids registered as of this writing. With about seven hours left to go in the auction, the top big currently sits at $135,300. At this rate, things could get very exciting at the end. Although to own a prototype for the first super bike, it might be worth it.

Acura to roll out NSX Prototype for Mid-Ohio IndyCar race

Acura will tease us yet again with its next-gen NSX when it makes an appearance at Mid-Ohio Raceway before the circuit's IndyCar race early next month. To be fair, the car's in-motion debut won't take the form of a production model - that's still a ways off - the vehicle will be a prototype. It'll be sporting custom graphics and an eye-catching paint (wrap?) job to draw the attention of the spectators, but really, we just want to hear this thing rounding the legendary road course at full chat.
The NSX prototype doesn't look to be much different from the various showcars we've seen over the last couple of years, with the same mid-engined, hybrid V6 power and all-wheel drive all present and accounted for.
The display will take place before the Honda Indy 200 IndyCar Series on August 4. The race itself starts at 3:00 pm and will be shown on NBC Sports Network.

Formula 1 seeking independent engine supplier

Formula 1 could get a new engine supplier in the near future, if Bernie Ecclestone and the independent teams gets their way. According to Autosport, the FIA is soon to open the contract up for bids, and there are already several manufacturers that have expressed interest. Currently Mercedes, Ferrari, Renault, and Honda supply engines – both to their own premier teams (Red Bull and McLaren for the latter two) but also to other teams like Williams, Sauber, and Toro Rosso. Because the new turbocharged V6 hybrid power units cost those four suppliers so much to develop, they're charging their customer teams big bucks – around $20-30 million per season – to provide the engines. These costs are much higher than the $10 million or so it used to cost to purchase a V8 engine under the previous regulations. Ecclestone figures it's time to bring in another supplier who will not run their own team and not play favorites, but will supply engines to private teams at a lower cost. There are already a number of potential suppliers under consideration. One of them is said to be Cosworth, which has a long history in the series stretching back to 1963. The British firm stepped back between 2007 and 2009, returned in 2010, and dropped out again after 2013. The development could be of particular benefit to Red Bull, which has been unable to find an engine supplier and could be forced out of the series as a result. The team has long been powered by Renault, but that relationship has grown sour. And the other three engine manufacturers have not been forthcoming in offering an alternative arrangement for the team.
