My 2 cents' worth:
1) How many times have banks repossessed "stuff" worth "so much" because the last two payments were overdue? That is normally called "armed robbery" but if your name is "Bank" then it's legal...

2) Pay Ca$h... that is not a "holier than thou" attitude, that is exactly the kind of advice my grandpa and dad gave me when I left home and got myself a job.
Was it good advice? You Bet ! Did I follow their good advice? I'll simply say that those FEW times I financed, something happened that got in the way and I regularly found myself "in the deep end"; but when I paid cash, everything always seemed to work itself out...
3) "Buy now pay later" actually means "get cheate now and ripped off later", the two most notorius being negative equity on mortgages and financing a computer for the family.
I can understand negative equity, as the T-shirt reads, "shyte happens", but financing $1000 for a $800 item that'll cost only $600 when I'll be done paying?

Even financing a used car ain't that poor business...
So, all I can say is:
Papi, figure out how much you paid and how much you still owe, and strip that much % off the bike, because it corresponds to the amount you already own.
AND
next time
consider a long term lease on a new item, it may be better business than financing a used item.
