$50 saddle bags on amazon: do they look right size and are o

[Water Warrior 2]

Believe it or not I can't remember the name of the top case. There are a bunch on E-bay that will offer reasonable security and are weather proof. Just make sure they come with a proper mounting plate to attach the top case onto. Then all you need to do is create a metal plate to replace the pillion and install the case's mounting plate on it. Really an easy job overall. I just fashioned a cardboard template and found the local metal fab shop to do the dirty work. After that it was just a matter of drilling holes where they should be. Used the 3 pillion seat fastening points so no extra holes were drilled into the bike. 2 bolt holes upfront and 1 at the rear on the fender.
I would suggest a slightly larger top case than 28 liters. Harbor Freight and JP Whitney sell knock offs pretty cheap that have proven to be popular and of reasonable quality. Usually made in China but who really cares if the price is right.
