I’ve featured a 18S before, but the AJS 18CS was a more aggressive long-stroke version. The C stood for Competition (as a scrambler bike), and the S stood for the fact that it had a suspension as opposed to a rigid rear frame. This particular example has been slightly customized to emphasize the “Competition” aspect.
Built for 15 years, the 18CS featured a 497cc single that produced 32 horsepower, which helped the bike attained a top speed of 81 miles per hour. Wet weight was 375 pounds, and the original MSRP was $425 – just under a dollar per pound! For more information, check out this write-up from Motorcycle Classics about someone’s experience living with a 18CS.
This specific AJS 18CS has been completely disassembled and restored, and comes with the solo seat, new tires, and original Jampot shocks. It took 1st place in a Barber Vintage AMCA Show with the most votes in class. The gas tank decal was apparently done in real 24 gold leaf.
