Obviously, they are an OEM, not a direct to consumer website.
"TEXA distributes its products through its own national subsidiaries"
Those subsidiaries sell through retailers. This is pretty standard practice not to publish pricing.
Companies selling as OEMs, especially though subsidiaries and such rarely post prices or, if they do, the prices mean very little. Go to the Ford website and you might get an MSRP which is worthless. The prices stated by MG aren't even close to what you pay for their bikes. Not by thousands.
