NO need for opinions thanks I received a reply from Dunlop
Thank you for taking the time to contact us with your motorcycle tire
questions. It is always best to match, exactly, tire brand, model and
tread pattern whenever possible. Correct matching of front and rear tires
is important to obtain optimum performance and handling. Mixing radial
tires, or radials with non-radials, may adversely affect handling and
stability. That being said, we do NOT recommend using the D402 and D404 on the same vehicle at the same time
