Get Vendio Gallery - Now FREE! LEGENDS MOTORCYCLES INC The Merchants of Vintage Offered again as the winning bidder was a dead beat. 1958 Ariel 500 model VH If you have questions email us before you bid. Offered for your vintage riding pleasure is a classic British single Ariel. The bike was sold new in Ft. Collins Colorado and spent its entire life in the state. Only two owners before we obtained it. The former owner owned it since 1976. He operated an independent motorcycle repair shop until his retirement. About 6 years ago he went thru the motor completely. For years this was his ride to and from work and used to explore the back roads in the mountains west of his city on Sundays. It is not stock as he modified it over the years to suit his needs. According to him the motor renovation included a new piston, valves and guides. A rod kit along with new pinion and sprocket shaft bearings were also installed at that time. It then received sparse usage after this work occurred. Alas, like a lot of us who have got a few years on us he found kick starting a large single wasn’t the fun it once was. It has new alloy fenders front and rear. The seat is a Bates style scrambler seat. The rubber is Dunlop K 70 universals. The frame isn’t modified as near as I can tell and it has a head light, no tail light. The bike has a clear Colorado title. It starts with a bit of effort and has tremendous compression. I can generally get it going in 5-6 kicks on a warm day. It could use some general cleaning up and probably would respond to some tuning to make it an easier starter. There are no other parts. What you see in the pictured is what is for sale. It is being sold as is and no warranty is offered as it is a 56 year old motorcycle. Please ask questions early to give me time to respond Please read and understand. This is our terms. Payment arrangements are as follows; If you have questions email before you bid. Successful bidder must make a $500 deposit thru pay pal within 48 hours of auction conclusion.

Shipping or bike pick up You are welcome to come for the bike with prior arrangements. We can pallet the bike and ship dock to dock in most parts of the USA for about $450.00. That means you will have to go to the trucking company with a truck or trailer to pick it up.

I'm listing this machine for a good friend who's not very computer savvy... In 1953, the ‘four pipe’ 997 cc Ariel Square Four Mk II was released, with separate barrels and a re-designed cylinder head with four separate exhaust pipes. This 40 hp Square Four was capable of 100 mph, weighed 425 lbs and cost £336.16. The last of the line, the MKII represented the peak of development of the Square 4s offering top performance, increased reliability and improved ride quality. This one benefitted from a full frame-up restoration by Canadian Martin Jensen and was acquired by the current owner with only a few hundred miles logged after the restoration. Jensen rebuilt the engine & gearbox, generator and regulator. The machine starts on the 1st or 2nd kick and runs beautifully. Although 'purists' will note that Jensen took a few liberties with chrome on a couple of the components, this is an excellent, fine running example with lots of attention to detail. Jensen sold the bike to the current owner with a solo seat installed and the current owner ordered a dual saddle from Draganfly - shown in the pictures. The dual seat did not come with mounting brackets, and remains to be permanently installed. The bike was storage-prepped soon after acquisition and displayed in the current owner's collection since. Detailed hi-resolution pics are on my Flickr page. The machine is located in Whitby, Ontario, Canada (just east of Toronto).

Posted Over 1 Month

Hello, this is a very clean 90% + restored Ariel 500 single. (restored to its road racing days). The bike was originally raced back in the 1950's / 60's, and then again in the vintage class in the 1980's. The bike has many of the modifications common to a bike like this. It also has a completely rebuilt engine and trans with zero miles on them. The bike was completely disassembled in 2012 and everything was inspected / cleaned / refinished in addition to any machine work needed. The engine has a new sleeve, piston, rings, cam, crank brgs. The head is a big valve alloy unit with new valves and guides. It has a rebuilt lucas racing magneto with a super hot spark. Frame and girder fork are original Ariel units, frame number BP1878. Girder has a gas shock mod in place of the original spring. Wheels are newly built with alloy rims and stainless spokes. New Avon tires. Bike has alloy fenders. Gas tank is nice, oil pressure gauge and tach on gauge are present but not hooked up (tach needs 90 degree drive from cable to clock). The bike is wired with a working headlight and tail / brake light, and runs off battery. Bike has a clean Colorado title, bill of sale will be included. This bike has oil in it and I regularly kick it over by hand to circulate the oil. I am selling for health reasons. This bike has not been started since all the work was done as I'm not able to kick it over due to knee problems. There has been no gas in the tank since being cleaned and lined. This is an easy finish for someone, I'd just like it to go to someone who will finish it and appreciate it. This bike took first place in the British bike show here in Denver last year. Other than taking it to that show no one has ever seen it. Shipping costs and arrangements are the responsibility of the buyer. I will help any way I can from this end. Deposit is due immediately after clicking the purchase button, full payment is due within 7 days of purchase and should be in the form of a certified check. Bike is sold as-is. Please ask questions, thank you for looking.

Beautifully restored by a marque expert! 1948 Ariel Square Four 4G Engine Number: CJ146 In 1928, engineer Edward Turner was shopping a new motorcycle design to English manufacturers. BSA turned him down, but Ariel was interested. The engine was an unusual four-cylinder. V-twins and inline fours, set both lengthwise and across the frame, had been used previously but Turner’s new design had two vertical twins sharing a common crankcase. The cylinder barrels were cast as a unit in a monobloc design. Their two crankshafts were joined by a flywheel and rotated in opposite directions. By having the two pistons of one crank at top and bottom dead center and the pistons of the second shaft at half stroke, the design was ingeniously compact and the firing order made it practically vibration free. The Ariel Square Four 4F made its debut at the 1930 Olympia Motorcycle Show featuring an overhead camshaft 500cc with a hand shift for the Burman gearbox, which was integral with the crankcase. Overhead camshafts and unit construction were well into the future for most firms, so Ariel was a real pioneer. Few knew then that the bike would become a legend of the British industry, both for its performance and dependability. The latter was underscored by the Square Four’s widespread used in the British law enforcement community. Improvements were continuous during the Square Four’s 28-year production run. In 1932, the 4F was taken out to 600cc, although the 500 remained available. The next year, a 4F 600 fitted with a supercharger lapped the famous Brooklands speed bowl at 110 miles per hour. The 4G was introduced in 1936 with a new 996cc overhead-valve engine. To accommodate the larger displacement, a new crankshaft was set in a much stronger crankcase. These years saw the British economy recovering in the run up to World War II, and Square Fours were seen on the road more often, where they were known as the “Monarch of the Multis”, referring to their multi-cylinder engines in a sea of British singles and twins. By the immediate post-World War II period, the 4G had a plunger rear end and telescopic front forks. To date, the innovative Ariel Square Four remains unique in motorcycling history; a true 'gentleman's motorcycle, this refined yet characterful machine retains an enthusiastic and loyal following, and is now a greatly appreciating classic, highly pri zed by discerning enthusiasts. The example of Ariel’s “iron head” offered here has been in the long-term ownership of a former engineer and motorcycle collector. A pet project, the bike started as a ratty barn find and was subject to a full restoration with a few modifications. At the heart of the bike is a motor fully rebuilt by marque expert Chuck Walton. Chuck’s tally now exceeds 110 engine builds and so to say he is an expert of the Ariel breed is just scratching the surface. His knowledge is encyclopedic and having restored so many engines, understands every pitfall of the unique design and precisely how to prevent engine failure. Tricks to rod bolts (a well-known weak point of the engine), rocker arms, crank bushings, valve guides and springs ensure engines with great power, superb reliability and great longevity. The engine is mounted in its original and unmodified, unmolested frame, fully restored with a fresh powdercoat finish in black. All cycle parts have been restored or refurbished. The result is a bike that starts easily and idles well. It has the enormous grunt of a Square 4 of 1000cc and sounds great. It runs cool and strong, shifting well with a good clutch. Brakes and suspension work very well for an old British bike. This is a great opportunity to acquire an increasingly rare piece of British history and style.
