Overview
In the small world of British supermotards, CCM has always played the card of the unusual. The 2010 404 DS doesn’t escape this rule, arriving with a large 398 cc single-cylinder engine where the competition lines up V-twins or compact four-cylinder engines. It’s a mechanical gamble that smells of grease and a desire to break away from beaten paths, far from the Suzuki DR-Z and KTM 690 SMC which dominated the segment at the time.

Its heart is a unique block of nearly 400 cc, with a generous bore of 90 mm for a relatively short stroke of 62.6 mm. A compression ratio of 12.2:1 announces an energetic character, and Keihin FCR39 carburetion, a resolutely old-school choice in the midst of the rise of electronic injection. With 40 horsepower announced, it won’t shatter records, but this engine is designed for immediate torque and a responsive feel, where many modern supermotards require revs to express themselves.
Lightness is its master asset, with a dry weight of only 128 kilos. Even once fluids are added, it remains within proportions that are dreamlike compared to the 150 kg or more of its Japanese rivals. This contained mass combines with a high seat at 850 mm, offering a dominant position on the road and urban agility that relegates most other machines to the rank of pachyderms. The 12-liter tank is just sufficient for playful sessions or a nervous daily commute, but not for long trips.
The tubular steel chassis with integrated oil reservoir is a signature of the brand, as are the WP suspensions, with an inverted 43 mm fork at the front and a PDS system at the rear. The braking, simple disc at each wheel, may seem light on paper, but it is perfectly sized for the low weight of the machine. This technical kit, simple and effective, clearly targets the rider who prioritizes feel and engagement over a dazzling spec sheet.
This CCM 404 DS Supermoto is aimed at the rider who is looking for an alternative to mass-produced models, a machine with a soul and assumed flaws. It will not suit those who want a sanitized and uneventful motorcycle, but it will seduce the enthusiast of tangible mechanics and raw sensations, the one for whom a carburetor and a large vibrating single-cylinder still represent the essence of two-wheeled pleasure. It’s an old-school supermotard, built without compromise, for journeys where the ride counts more than the destination.
