1956 HS mkIII             Posted Feb 2015
1956 Ariel HS 500 Single.
Excellent mechanical and cosmetic condition. One of 229 made according to the factory records. Dating certificate confirms original engine, gearbox and frame. Originally sold by Johnson Motors Co. New Amal 389 carb; new clutch, primary chain and sprockets. I've put about 1,000 miles on it and it starts easily and is a strong runner (even compared to Gold Stars!). Correct levers and shocks (original paint?!). Everything works including all electrical and gauges. Lots more history - call or email Mike for more information at 541-923-6193 or
1955 VH/HS ISDT Special      Sold!       Posted Jan 2015
1955 Ariel Red Hunter VH/HS 500 Single.
This a very unusual Red Hunter especially, if you are a fan of Jeff Smith, Dave Bickers (they've autographed the tank) or the ISDT. It would be a great addition to a collection or just an outstandingly great bike to own and ride, as I have. This Red Hunter was restored in England by Andy Tiernan to the 1955 ISDT specs in which it was supposed to enter. This Ariel came from the factory with the alloy HS engine. I have a certificate of authenticity from the factory records supplied by the Ariel Club of England. This racing Red Hunter is equipped with a host of features for competition that you just don’t see anymore. Compressed air bottle (for fixing flats), front mudguard nail catcher, ISDT head inspection tag, extra cables (clutch, brake, throttle) laced next to the operating ones and an original tank bag, racing air filter and more. I added a SRM electronic ignition that fits inside the original magneto housing. I also added LED bulbs to headlight and rear stop light. This Red Hunter is a ball to ride. Starts first kick and runs unbelievably strong. Just installed new shocks so the bike rides better than you can imagine. Everything works. Chrome is perfect and the paint is in good condition. Sold!
1958 Sq4 MkII                   Posted Dec. 2014
I purchased this Ariel from Arlin Jeffries in 1997. Rode it 27 miles (to 22,430 total) and then put it on display in my den. Arlin purchased it in 1962. Runs fine, way too much power for me, has none of the post 1997 upgrades. I cleaned it up pretty well but alloy castings need polishing. This is not a show bike but is quite beautiful in a 56 year-old kind of way. Bike is with me in Seattle. $25,000. For more info contact:

Well sorted 1958 500 Red Hunter Sold!            Posted Jan. 2013
1958 Ariel 500 VH, good condition, ridden frequently, $6,500.

Too many bikes and projects. The VH is one that works, not a project, that I take out on warm Sunday afternoons and ride to an occasional Brit Rally. My reflexes and skills are declining and I find myself going out now on a more modern bike more often than selecting the VH. I will hate to see the Ariel leave, but it should be used and appreciated by someone else now.

Asking $6,500. Sold!
