Thessler..prior to 2007 Honda recommended 10w 40 for its 4 stroke engines. After Jan 1 2007 Honda recommends 10w 30 for its 4 stroke engines. Not sure why the change, but its true. ( see highlight on Honda oil recommendation chart below)
Not saying 10/40 will hurt your motor ( I use 10/40 in my 2006 ST 1300 which is what Honda recommends) but the owner of a 2007 ST 1300 is advised to use 10/30

If you feel confident using 10w40 by all means do so.
