Stickman you are correct, in 78 theres the 400T1 which is spoked wheels and drum brakes. The 400T2 has comstars and a front disc brake and the Hondamatic, for some reason I think theres a hawk with spoke wheels and front disc but that might be a different wheel. My wife has a Cb400T2, great city comuter/rider but a little under powered on the highway. Tops out at around 115kms, great little bike though. Pretty bullet proof.
