dkw supercharged 250/350 1936/40 by the looks :D Possibly the most aesthetically pleasing, most advanced & fastest prewar light motorcycles of all time..The supercharged deeks led to the banning of supercharging in racing grand prix & TT machines ,,,ps

built a plastic model of one when i was a kid lol

I know, I know, it's hard to believe but if you look at the picture long enough you will start to see a motorcycle. Your mission is to guess what year, make and model it is.

It IS a DKW but not supercharged and not a 350. Keep trying.

Hint: it is up for auction this April with a pre-auction estimate of £100,000-£120,000.

 

1937 ss 250 split single These engines also have a Ladepumpe under the the engine, which is a separate cylinder used to compress air into the crankcase - a kind of supercharger for two-strokes. Thus, while this motorcycle is technically a twin-cylinder two stroke, mechanically it is a 5-piston machine - hardly a 'simple two-stroke

Your cut and paste of snippets from the article about a DKW 1937 SS350 are valid for that model, but my pictured offering was a 1938 DKW SS250. Not sure if the SS250 had the same Ladepumpe set-up as the SS350.

My DKW is here: http://www.classic-auctions.com/Auctions/23-04-2014-ImperialWarMuseumDuxford-1366/1938DKWSS250-37616.aspx

1974 Benelli Quattro 500 GP racer

clone.

This is not a true factory GP bike, the tank fairing, brakes are not correct. Must be a street bike converted.

The link I found said that this one was painstakingly restored, but they're trying to sell it so......

 

How is it that you know which should be correct for a factory bike?

At the time of the attempted sale on eBay, four years ago, there was a minor stink going around about it's authenticity. Some noted that the factory GP racer would have an alloy tank whereas this specimen had a fiberglass tank. The front brakes, while duly noted as leading shoe drum brakes, were not the same as the factory GP racer's 4LS. (And some said the 1974 factory GP racer had disc brakes up front. I dunno.) The brakes on the pictured bike are from a Benelli 650 Tornado. The seller, when questioned about the history of the bike, responded vaguely:

Q; Can you provide a 'history' for this bike? Dave Jan-17-10

A: The bike sat in a barn in Minnesota for 30 years until Kent aquired the bike and restored it to museum quailty. Thanks for your interest!

 

Q: does this machine have any history....... race or otherwise?thanks Jan-17-10

A: The bike sat in a barn in Minnesota for 30 years until Kent aquired the bike and restored it to museum quailty. Thanks for your interest!

 

Doesn't really say too much about it's racing provenance does it?

 

Finally, on the builder's (Kent Riches) own website:

http://airtech-streamlining.com/benelli/benelliquattro500.htm

he depicts the very same bike and notes:

The 500 Quattro on your left is another Kent Riches restoration. The original was in ways a parts bin special so we don't feel shy about fitting a Honda CR750 fairing and Norton Commando Production Racer tank to it.

Pretty thorough, I'm lucky to be able to find one confirming photo after looking for longer than I can really afford to.
