This is information for the Givi B37 blade top case. I got the case used (new) from marketplace for $75. Since I am riding solo and I am using the top box for light duly (helmet, gloves and jacket), I decided to skip the SR357 rack (cost and a few minor problems in the forums). There is one in for sale forum for $100 with $25 shipping or $160 new from most online with free shipping. If you want to save some $, you can use the free mounting plate that came with it. The generic mount plate will work and 1 minor modification to it. You will need longer M8x1.25 bolt, couple of plastic spacers and a few metal washers (all from Lowes). The mod is to cut the middle rear bolt location in the plastic mount so the metal washer can lay flat. Install a plastic spacer to level the plate above FJR rack, then a washer, then the mount givi plate, a washer above the mount plate with a bolt. It's pretty strong enough for light duty carry.

You do realize you're looking to save $160 on an SR357 rack and risk a possible $600+ sub frame?

I will definitely upgrade if i am going to pack for a road trip. I am using it right now to store my helmet and my jacket when stopping somewhere. Thanks for bringing up the subframe issue. This is new to me.

When you do the bolts up, just make sure that nothing is stressed and that it tightens up evenly.
Be aware that Givi boxes have a habit of falling off on bumpy roads. Drill a hole through the bottom of the box and the rack and use a roller pin and clip or a nut and bolt to secure it to the rack.

Thanks for the tip. I will definitely check on the "evenly" tightening process. I will research boxes falling off issues.

I thought it was the Yami boxes that would jettison.

You can keep it waterproof with a rubber washer or dab of silicon sealer. Then it becomes a project whenever you want to remove the box.

I am sure I can probably engineer some quick release mechanism.

on Givi website, they are saying 6kg for e228M and 10kg for SR357. How much weight can you put in each pannier?

Speed, let me add to this and tell you Whooshka is 100% correct. Take it from somebody that has experienced this. My Shad 50l I used basically empty 95% of the time and then just stored my helmet at stops and my lunch bag going to work when I took one.

I had a “Stiffy” kit installed from nearly new because of advice and encouragement from a lot of good folks here. Because I had so many problems with my bike from new and a lot of encouragement from my dealer they waved the $675 cost for the new frame but said they wouldn’t pay for the installation which the dealer estimated would be around $1000.

I’m pretty handy and after 7-10days had the new frame in, I modified the heck out of the Stiffy to add a lot more support in addition to installing the new heavy aluminum Yamaha rack, the Yamaha reps said a max of 10lbs with the new rack and a max of 7lbs for the oe plastic shite (wanna buy one ?)

Anyway if you think saving that $160 is a big deal, go for it, oh by the way if you don’t have a Stiffy installed there’s a really good chance that you’ll learn of your broken subframe when your new lightly loaded topbox goes tumbling down the road behind you. My .02

Thank you for the advice. After a bit a searching it is a structural engineering design flaw (IMO) with the subframe. I do plan to use a stiffy. So even with the Sitffy kit, your subframe cracked?
