It's hard to interpret the results of this year's Las Vegas auctions. A look back to our preview last week will show that most of the bikes with really high estimates failed to sell, yet an analysis of the top 50 bikes to sell during the three day event shows many world record prices for models and marques, high sell-through rates and gross numbers larger than ever.

Vincent motorcycles dominated January's Las Vegas Motorcycle auctions this year, with seven of the top ten most expensive bikes of the two auctions, and a new world record for any Vincent motorcycle of US$434,000 going to a Chinese Red Vincent White Shadow 1000cc V-twin

At the top end of the marketplace, there seems to have been an expectation from sellers that was not met by buyers, and as reserves were set above what the market was prepared to pay, the "zone of potential agreement" between buyers and sellers at the top end has evaporated almost entirely.

The mid-range in the market, though, grew in Las Vegas with seventies motorcycles in particular selling for record numbers.

We're preparing a market analysis at present, so here's a list of the links and a brief synopsis of the top 50 motorcycles to sell in the three days of auctions, plus a few interesting bikes which sold for a lot less.

$434,000 – 1951 Vincent White Shadow

Bonhams Lot 135 was the star of the three day auction, being one of 15 White Shadows ever built, and the only one made with a Chinese Red paint scheme. Sold by just it's third owner, the bike has a number of subtle but significant mods, including Carrillo connecting rods, more modern Amal Mk.II carbs, electronic ignition and a two-step, high-volume oil pump, plus the bits which were replaced and 200 pages of restoration receipts.

Vincent Black Shadows are the most prominent single model in the top 250, but the most valuable Vincent Shadow is the White Shadow as only 15 were ever built, and at the same Bonhams auction at Bally's Hotel & Casino held one year ago (January 2015), a 1950 Vincent Series C "White" Shadow sold for $224,250, setting a world record for the model. This bike is now the new record holder for the model, and the marque, surpassing the previous most expensive Vincent to have sold at auction, a 1939 Vincent Series A Rapide which sold for $418,940 (£275,900) in April, 2015.

$181,500 – 1912 Henderson Four

Mecum Lot S74 is a first year Henderson Four. One of the rarest machines in the world with only about a half dozen known to exist, this bike is fully restored having been last registered in South America in 1937. This bike already held the title of the most expensive Henderson ever sold, having fetched $225,500 at the E. J. Cole Collection auction in March, 2015. This time around, it fetched $50,000 less. A 1917 model also sold for $209,000 in March, 2015.

$164,500 – 1955 Vincent Series-D Black Prince

Bonhams Lot 151, a 1955 Vincent Series-D Black Prince, became the most expensive example of the fully-enclosed Black Shadow ever sold at auction, surpassing the previous record of £91,100 ($153,094) set in June 2014 for another 1955 model which was in basketcase condition. Only around 200 Black Princes were ever built.

$153,500 – 1948 Vincent Series-B Black Shadow

Bonhams Lot 108, a 1948 Series-B Black Shadow, is something of a rarity with just 76 being made before Series-C production began in 1949. Over 1,500 of the Series-C Black Shadow were built, so on the basis of scarcity, this bike in particular could have gone higher. With all the numbers being right, it resulted in a world record price for the model.

$142,500 – 1953 Vincent Series-C Black Shadow

Bonhams Lot 95 is a 1953 Series-C Black Shadow with a complete history and an odometer reading that is believed to be correct, of just 14,600 miles.

$137,000 – 1951 Vincent Series-C Black Shadow

Bonhams Lot 152 (link to official auction page)

$132,000 – 1955 Vincent Series-D Black Prince

Mecum Lot S174 was the second Black Prince to sell in Vegas during the auctions, establishing the model in the $135,000 to $165,000 range.

$126,500 – 1929 Cleveland Tornado

Mecum Lot F141 is a 1929 Cleveland Tornado, the final incarnation of the Cleveland four before the company went into bankruptcy in the months following the Wall Street Crash of 1929. Cleveland is best known for it's four cylinder bikes, but in becoming the most valuable example of the marque ever sold at auction, it displaces on of Cleveland's 220cc two-stroke singles. The 1919 Cleveland 13.5ci which was sold by Bonhams for $93,600 in 2007, had been restored by Kennie "Von Dutch" Howard in the early 1970s for the Brucker family's famous "Movie World Cars of the Stars" museum in Buena Park, California.

$126,500 – 2004 MTT Y2K Turbine

Mecum Lot S148 is a turbine-powered Marine Turbine Technologies Y2K producing 320 hp and 425 lb.ft of torque, one of the fastest motorcycle in existence. An unfaired Y2K has been clocked at 233.7 mph (376.1 km/h) over a flying mile. Not many of these bikes have been built because they sold new in 2004 at nearly $200,000 each, and hence even fewer have gone to auction.

The previous record for the model was held by a 2002 model which sold for $89,100 at the Barrett-Jackson's Petersen Museum auction at the Barrett-Jackson's Petersen Museum auction in 2004. Still in production, now with a 425 hp motor, the future for MTT's turbine motorcycles looks bright on the auction block, considering how youthful the brand is and that bikes of ten years of age rarely sell for anything like their retail price for many years.

$125,000 – 1954 Vincent Series-C Black Shadow

Bonhams Lot 109 (link to official auction page)

$121,000 – 1956 BSA Gold Star Clubman Cutaway

Mecum Lot S175 is a 1956 BSA Gold Star Clubman Cutaway built by BSA for the 1956 Earls Court (London) Motorcycle Show, the world's most important at the time – the cutaway BSA Gold Star is electrically driven to show movement of the engine internals, wheels and suspension. The mechanical masterpiece was the subject of a feature in Gizmag when the bike went to auction in 2015 but failed to sell.

At that time it was expected to fetch between $250,000 and $350,000, roughly 10-20 times the price of a well restored example of the sectionalized model displayed. While the marketplace finally judged it to be worth less than half of that value, it is still the most valuable BSA ever sold at auction. The previously most expensive BSA was the 1973 Triumph TRX Formula 750 triple (it was really a BSA Rocket Three) which sold for $104,760 in Las Vegas in 2014 by Mecum MidAmerica.

$120,500 – 1977 MV Agusta 750S America

Bonhams Lot 101 is a 1977 MV Agusta 750S America with just 41 miles on the odometer. The original owner purchased this bike in the summer of 1978, rode it for 41 miles and then hid it away in museum-quality storage for 45 years. Only 540 Americas were ever made. The record price for an MV Agusta 750 S is £85,500 ($143,661) achieved by Bonhams in April, 2014 and making this the second most valuable example of the marque to sell at auction.

$120,500 – 1938 Brough Superior SS80

Bonhams Lot 153 is a Brough Superior SS80 with a SS100 engine, meaning it should be capable of sustaining 100 mph. From 1924 to 1936 these bikes used the twin-cam JAP KTOR v-twin and for what proved to be the final two years of SS100 production, Brough switched to the 990cc overhead valve v-twin Matchless BX engine. Only about 300 of these Matchless SS100s were produced.

$115,000 – 1910 Royal Pioneer 30.50 ci (500cc) single

Bonhams Lot 120 is a rare 1910 Royal Pioneer 30.50 cubic inch (500cc) single, one of just four known to exist of the 500 produced before fire swept the company's new factory in December 1909. Production ceased with the fire. The bike in Las Vegas already held the world record for the marque when it sold for $92,000 in May, 2010. This time around, the bike sold for $115,000, pushing the record still higher.

$115,000 – 1971 MV Agusta 750S

Bonhams Lot 161 became the third most expensive MV Agusta in history. It's slightly rarer than the MV Agusta America which sold at this auction for $120,500, but not in the same "time warp" condition. Beootiful plumage!

$103,500 – 2007 Confederate B120 Wraith

Bonhams Lot 114 had a very conservative estimate of $38,000 to $44,000, at which price it would have clearly been an absolute steal. Few machines ever regain their initial purchase price, particularly in the first decade, but the Wraith is already close. As we said in the preview of the auction, "If you believe, as I do, that the Confederate brand will endure and prosper, then the 1999 Hellcat and the 2007 B120 Wraith offer prime investment potential."

$103,500 – 1922 Ace Four with sidecar

Most American four cylinder motorcycles owe something to William Henderson, but it was Henderson's second attempt at building a four cylinder motorcycle from scratch, the Ace, which became his defining legacy. Henderson was killed aged 39 on 11 December 1922 in a motor vehicle accident while testing the new Ace Sporting Solo in Philadelphia, a direct relation to this machine. Though production continued for several more years, the soul of the company died that day.

Bonhams Lot 119 was produced in the same calendar year, one of just five years of Ace production. It's hence not surprising that those Aces that remain in existence are beginning to rise through the rankings of the world's most valuable motorcycles. The world record for an Ace Four was set by a 1923 model in August, 2010 when it sold for $128,400 at a (now Mecum) MidAmerica auction. Another Ace Four (a 1920 model) sold for $126,500 at the E.J. Cole Collection auction on 21 March, 2015. This bike becomes the third most valuable Ace to have crossed the block. Ironically, a 1920 Ace Four was passed in at Mecum with a high bid of $150,000. Had the reserve been met, that bike would have become the most valuable Ace ever sold.

$103,500 – Steve McQueen's 1963 Triumph Bonneville Desert Sled

Bonhams Lot 121 was a 1963 Triumph Bonneville trail bike which was ridden extensively by Steve McQueen, after his friend and trail riding buddy Bud Ekins built it for him and another friend, Kenny Howard (better known as Von Dutch) painted it. The bike had a very conservative estimate of $50,000 to $60,000 given it had sold previously at a Bonhams auction in 2009 for $84,240, becoming the most expensive Triumph ever sold at auction.

The modest price increase makes it is still the second most expensive Triumph ever sold at auction, exceeded by only the 1973 Triumph TRX Formula 750 triple (with a BSA three cylinder engine) which sold for $104,760 in 2014. The other McQueen bike on sale was the 1949 Indian Arrow which was used by Steve McQueen to teach his wife Barbara how to rebuild a carby. It failed to sell with a high bid of $50,000.

$100,050 – 1928 BMW R57

Though there were more valuable BMW motorcycles available in Vegas, this bike eventually became the most expensive of a bevy of desirable BMWs. BMW began manufacturing motorcycles in 1923 and for 1928 it introduced the new, overhead-valve R57 sports 500cc twin with a square 68 mm bore and stroke, a hand-shift 3-speed gearbox and electric lighting, not a bad specification for 88 years ago. R57 production lasted for only three years and not surprisingly, this bike, Bonhams Lot 139, set a new record at auction for the model.

$99,000 – 1939 Harley-Davidson EL Knucklehead

Mecum Lot S65 is a 1939 Harley-Davidson EL Knucklehead, one of the most important American motorcycle models ever produced as it set Harley-Davidson on it's current path of styling. Indeed, the Knucklehead also had a duplex frame, and the first OHV Big Twin from Milwaukee for the street. The record for a Knucklehead at auction is held by a 1936 model which fetched $178,200 in 2014.

$94,300 – 1913 Pope Model L Twin

Bonhams Lot 123 is a 1913 Pope Model L, a 70 mph 1000cc V-twin produced for six years until 1918, and at the time of it's introduction, the fastest production motorcycle in the world. The world record for the marque and model is $126,500, set at the E. J. Cole Collection sale last year.

$92,000 – 1950 Vincent Black Shadow

Bonhams Lot 80 (link to official auction page)

$99,000 – 1914 Flanders Model D Twin

Mecum Lot S113.1 is the only known Flanders V-twin in existence, selling for $88,000 as part of Gooding's Otis Chandler Collection in 2006, then selling again at a Bonhams auction in 2010 for $78,200 and at it's third auction in 10 years, it narrowly failed to pass $100,000. $100,000 for a one-of-one, century-old American V-twin seems cheap to me.

$94,600 – 1937 Brough Superior SS80

Mecum Lot S158 is a mostly original 1937 Brough Superior SS8.

$80,500 – 1955 Vincent Series-D Rapide

Bonhams Lot 178 is a 1955 Vincent Series-D Rapide rebuilt to Black Shadow specification.

$85,250 – 1929 BMW R63

Mecum Lot F167 is the 750cc version of the 500cc R57 (one sold higher in this list) and equally as rare. It narrowly missed out on a new record for the model, which is held by a 1928 model which sold for €67,850 ($101,504) at a Bonhams auction in 2010.

$79,750 – 1917 Henderson Board Tracker

Mecum Lot F69 is a unique Henderson four board tracker, the only Henderson board track race bike known to exist.

$77,000 – 1912 Pope H

Mecum Lot S155 was an unrestored running 104 year-old motorcycle. This bike took first place in the antique category and the FIVA Preservation award at the Quail Motorcycle Gathering in May 2015. This bike was part of the famous Floyd Clymer collection.

$69,575 – 1948/1970 Egli-Vincent

Bonhams Lot 177 is an Egli-Vincent built in 1970 around a Rapide motor which had been rebuilt to Lightning Spec.

$66,700 – 1970 Harley-Davidson XRTT 750cc

Bonhams Lot 51 is one of the rare iron-barrel XRTTs used until the all-alloy engine was ready. The XRTT road racer was the last American motorcycle to be competitive in outright top tier road racing. It handled well, but was notoriously unreliable, and the iron barrel version ran so hot that it was nicknamed "the Waffle Iron."

$71,500 – 1940 Indian Four

Mecum Lot S92.1 is a 1940 model Indian Four, one of the most beautiful and voluptuous road bikes in history, which was only styled that way for three short production years. The Indian Four came into being when Indian bought the assets of the Ace Motor Corporation in 1927 and continued until 1942 when production was ceased due to the war effort, never to be restarted.

$68,750 – 1911 Thor Single

Owned by just two families since new, this 105 year old machine not only runs, but runs well. It is one of the stars of the JT Stewart Collection Collection which Mecum sold in Vegas. A bargain at this price.

$57,750 – 1974 MV Agusta 750

The third MV Agusta 750 (Mecum Lot S184) in Las Vegas is an example of what happens when you deviate from standard specification. The 912cc engine of this bike is the work of master MV Agusta builder Albert Bold, and has handmade billet cylinders, a Magni style head with larger stainless valves, aluminum bronze seats, and larger intake ports, an upgraded set of Magni 30mm Dellorto carburetors and the highest engine# in the MV Registry (#221-0395). It is most certainly one of the last, if not the last America from MV. Despite the heritage, it went for half price.
