All TM RACING partsTM RACING MX 400 4T
The MX 400 4T is a proper old-school four-stroke. Big-bore thump, mid-range that hits hard, and a chassis built for riders who like to lean on it. Keep the top end honest: shim the valves, check cam chain tension, watch for stretch. Don't ignore the cooling either. Old hoses go soft, clamps loosen, and these motors run hot when pushed.
