GSX-R Torque arm mounting

He talks about single shear and relying on the bolt to bend. Bending bolts after a while break. Fred added the spacer which increased the surface area and reduced the bending. Still playing Russian roulette

This is obviously a contentious issue, like tyres and oil, and I can see both sides of the argument. In my experience the Suzuki brakes couldn't stop an argument, and have only locked mine up on two occasions. Both times were in emergency braking situations, with very little weight on the rear.

I have a lug/tab welded to the underside of my swing arm for the torque rod to attach too. $50 (mostly labour cost) well spent in my humble opinion.

The gsxr600 bracket has a bar/ lug that slides in a channel that I have welded to the inside of the swingarm. Slides forward or back for chain adjustment.

Have same setup on both bikes. Till I get around to mounting the slightly longer R1 swingarms( will help keep the front down on the 1350, and later on the turbo bike.

Here's a picture of how I used to have the lug/tab welded to the bottom of the swingarm. And a gratuitous picture of the 1350. With the current 600 bracket.

The main reason people, myself included mount the torque arm to the foot peg bolt is because of the length of it. The torque arm I have is a genuine gsxr one and is roughly 500mm or just under 20 inches long, so it impossible to mount it to the swing arm. The foot peg bolt lines up pretty good for the caliper to sit reasonably flat and look kinda factory. I've always been a bit suss about the strength of the mount, plus with the braking power being virtually non existent don't even use the rear brake anymore, only when stopped at the lights etc. I could source a shorter one and mount it to the swing arm but that won't improve the braking power so I'll just leave it how it is.
