Title: How much swingarm travel is likely after installing the RPM rear shock
Post by: nurse on January 28, 2014, 04:33:47 PM
I know this is a 'how long is a piece of string' type question but here goes.

Have fitted Randys rear shock and am currently fitting a delkevic system from collector box back.  I am the point of mounting the end cans and can't help but think they sit too close to the bike and there may be potential for the axle nut to connect with the end can.  Have measured about 100mm clearance before it will touch and was wondering what is likely to be a typical amount of 'swing'

I am not going to leave the exhaust set like this before barrage of move it out the way type abuse is hurled at me (it's only loose fitted at the moment), but it got me wondering!!

100mm of clearance from loaded ride height or on the center stand?

Here are several videos of the rear wheel in action so maybe you can determine if the new pipe will interfere from them. (look for the big bumps)

Hi Randy

Thanks for getting in touch. 

The measurement is on the side stand without any other weight on it.

Looking at the footage I will have to make sure the clearances are safe!!

I didn't want my cans sitting too high and found they can be tweaked to clear the axle nut before tightening everything up. It's not far off where they naturally want to sit anyway.
I just stood a steel ruler vertically against the nut check clearance.
Once fitted they can also be moved out a bit with a good tug.(some here have unkindly suggested I am experienced at this procedure)

It has never occurred to me that they look like they are sitting too far outboard.

I found that my axle goes past the pipe easily. I had to make a stronger bracket to keep the exhaust from rubbing (with the RPM shock), so I believe you would have to ensure you have some clearance, you'll find the rear end will go down at least 30 to 40mm when setup correctly (with the rider on board and feet resting lightly on the ground).

Randy, nice videos of the shock movement.
