Download this app this has a resale value calculator & take a mechanic with you check the condition & negotiate
My honest opinion
They discontinued it for a reason
Another app
This one
It gives accurate details of each and every vehicle's owner.
Even Truecaller is misused
Even if you don't download Truecaller, still Truecaller has your information.
For example: Your Freind has Truecaller installed in his mobile, he also has your number saved. Truecaller can access his Contacts so automatically your number will be added to Truecaller even if you don't want to.
Use one of those Vehicle Information Apps. Here is the link to one of them :-

You can find the owner info of the bike through this app.
