I,ve seen 3 different zx sleds with 809 triples in them this past year and talked to there owners and 2 of them said that the sled was slower than the ck3 chassis. I seen one run radar and was 5 mph slower than my mxz800. I beleive there is not enough engine and clutch cooling in that chassis aswell the pipes will not be as effeicent as the ck3 and the ck3 is a faster chassis less rolling resistance and more areodynamic. IMO
