Have to say that I also didn't like the long motor mount bolt either. The bore of the right side cage barely catches on the bolt hex. Only the tips of the hex actually contact the hole on the right cage. It was too little contact area for my taste. I was almost ready to send them back (had MC on the phone). As I was speaking with them I came up with a solution that I felt solved the problem. I took a flat washer that fit into the right cage bore and cut it like a lock washer. I was able to bend it open to fit around the bolt, then bend it back closed. Once inserted into the right cage bore the washer gave full support and is captivated. This was really the only weak construction point of the canyon cages. I'd recommend MC to put a washer on the bolt first, then weld the hex in place. That would solve the clearance issue. Oh, and I'd like to see the left side stand off and nut powder coated black also (I painted both before assembling).
Other then that I really love my canyon cages, they're the best bars!!
Agree with you on the appearance of the long bolt , wouldn't making it out of stainless be an alternative - but I have a different problem with this long bolt.
It arose when I wanted to remove the cages and then ride the bike to the shop that does my servicing.
Removed the cages and then tried to use the standard bolt but it jammed solid when trying to push it through.
Reverted to the cage bolt but felt it didn't tighten up properly . but had no choice but to use it.
On returning from the service I had a look at the mounting and found that the motor had dropped so that the standard bolt would no longer pass through. The cage bolt hex had started to gone through the hex on the motor and was starting to seat on the smooth bore and eat into the aluminium and that's what didn't feel right when tightening.
On measuring up the bolts I found the following :
Bolt diameter; OE 11.8 mm , MCE 10.9 mm
Hex across flats : OE 13.5 mm , MCE 12.4 mm
The narrower diameter of the MCE bolt and hex had allowed the motor to drop down a small amount and that was enough to prevent the OE from going through.
Did raise this with MCE but no response as yet.
Have now cut some slots in the fairings so I will be able to remove them without having to take the cages off
Apart from the slight dropping the motor and the inability to use the standard bolt when riding without the cages , does anyone think that this could have any other detrimental effect or does it indicate that the lower mounting could be under tightened and this is what allowed the motor to sink the 1 mm ?
