Well, this anime has not been published in English and has no official English title. IMO, to use the translation of the title in this case, it's quite acceptable. Yuto is the name of the main character and can not refer to "kids".
The inscriptions on the sides of the back cover and on the obi does not contain "Silk Road Kids" (I think that's just a part of the logo art, nothing more). Even the composer of this soundtrack, Yoshihisa Hirano, writes the title of this anime as
Silk Road Shounen Yuto (No.3280)
Edit:
But if you insist that the "Silk Road Kids" is the part of the title, then the full title should be something like "Silk Road Kids ~Silk Road Shounen Yuto~ Original Soundtrack"
