Ardbeglily, I have contemplated the same subject many times for my 2017EX. I did not see any year posted for your CB, which will make a difference for some of the pre-cut kits out there, because of changes in the shape of the tank. I like the look of the TechSpec, and the ability to peel off and reposition if necessary, but I think the shape of the pads is more suited to the pre 2017 tank shape.
If your bike is 2017 or later, I think the pads Treedoc has listed from WeBike Japan, are the best complementary shape I have seen to this point.
