The answer appears to be no.
If the title is solely in your name, that should control. How there was a loan given to your wife with your mtorcycle as collateral is another question. There may be a need for her to discuss this with her BK7 attorney. A simple resolution may be giving a copy of the title to the attorney showing she is not a holder; if need be, the attorney can then produce it to shown this to the Trustee.
As to the loan, it may be discharged; your wife may face a non-dischargeability claim. There may be no further need for payment, but, again, this depends on what the loan note/agreement actually says. An attorney review might be in order. It does seem that, regardless of the loan, the motorcycle should not be included as an asset - exempt or otherwise - in her BK7.
