Kayo K6 Engine SOHC OR Dohc?

[Hawk 250 pnw]

I've read in multiple places that the kayo k6, k6r have the same nc250 engine,



The only problem I am running into is on their site and multiple places am I seeing it listed as DOHC example https://www.ridekayo.com/k6-r-250 except under the service manual it says it's a SOHC??? https://www.ridekayo.com/_files/ugd/72abb6_1a7bff543cfe456781e438e1393cad99.pdf

I can see it's a DOHC, The service manual is wrong. Does anyone have a service manual for the NC250 DOHC
