lt250r shocks

Yes you can resell them for much more that $20 so you have only to gain! =] Give it a shot. You never know. I found out just last week that '79 XL100 shocks fit on my Blaster. lol
 
They aren't made for a blaster. So no. It would be a waste of 20 dollars. Keep saving and get some used aftermarket shocks that were actually made for the geometry of a Yamaha Blaster.
 
^Really dude?^ A waste of $20 to possibly have a beautifully riding suspension? If not you can sell them for twice your money. No loss there. Banshee shocks aren't made for Blasters but they work don't they?
