aluminum aircraft type metal can withstand pressures way beyond 325lbs at ~60mph hitting asphalt. plus you kind of want it to crumple because it absorb the initial blow.Yeah it definitely looks like that long gap where the bracket mounts between would be the first point to fail.
Sato has used this same type of mounting system on the GSXR600/750 for 3 years, as well as other bikes, CBR1000RR ZX6, Buell, Etc.
It has worked very well, including the bolt design that holes the slider on, they have not broken off, the slider has worked as designed.
Looking at the pictures of the Sato's and the Shogun sliders, the first thing I see is how long the Shogun sliders are.
This is something Sato tries to avoid as the longer the slider the more leverage there is working against the bolt and the mount.
I will mount a set up on the bike I have here and take some pictures with the fairing on.
This bike has a race fairing on it.
Here are links to pictures of the CBR1000RR 2008-09 sliders and the GSXR600/750 2006-09.Dan I understand you are a site sponser and sell Sato. But go back and look at the GSXR,1000RR's. They both have a backing. They are not hanging in between two bolts with no backing behind it.
Also do you have any racers that you are backing on the 250 that you are willing to send a set and back up the claim?
