The K7 belt is the same as K8 and later. K7 is when Suzuki did the big upgrade to the 400, engine, body, brakes etc. Suzuki resolved a few upgrade problems in K8, namely a three shoe to a five shoe clutch and a larger exhaust gasket (btw, if you have a K7 and need to replace those parts, get the K8 part, they're better).Thanks men....This is all very strange, so many belt options for a 400. Many for k8 k6 k2 blah blah, not much for a k7...Any difference??? Yes mine has double disc on front.
Abit outrageous prices for a bloody belt, there goes all our fuel savings.
