Are we talking about the link arm bushes? If so use a socket to drift them out.

If the frame is anything to go by I assume the powder coater painted them in as well which won't help.
I assume you are aware that the swing arm link element its made of 3 parts, the through shaft, an inner bush/shaft that runs full width, and then 2 outer bushes, one per side, approx 40mm long from memory.
The original outer bushes were made from a plastic material, often replaced with bronze ones.
Just thought I'd mention this as may help when you know what you are trying to drift out!

If all else fails a long hacksaw blade and carefully cut two grooves one at six o'clock the other at four o clock not as far through to the alloy of the arm and split it with a small chisel it will relive the tension in the outer shell and drop out but do it slowly only want about 2 mm deep cuts max,, be brave and don't go wild with the hacksaw

No worrys mate donne this for years on stubon outer Bush shell it works a treat as releases the preasure and basically you give it space to collapse in on itself and it drops out

Sorry, not that this will help you, but I have machined two half circle bushes for drifting things like this out. You drop one half in, then the other and centre them. You can see an RGV swingarm drift in the last pic top row, second from left. rdlccrazy.proboards.com/post/496513/threadJon |

Just had this on a Kawasaki Triple, in the end I carefully hacksawed the flange of the plastic outer stepped bush. This left the steel inner bush protruding about 1/8 inch.
Plenty of heat and pounded it back through using a stepped bush driver from a kit I bought ($23 Amazon). Once I got the steel inners out the outers were removed with large bronze drift and heat again.
I got bronze replacements as the OEM Plastic crap didn't impress me. To fit them don't ever pound them in. I heated the swingers a bit and pressed them in with 1/2 in steel threaded rod and thick washers and nuts either end (A few bucks at Home Depot). Went in like butter. The problem with bronze is to get the steel bushes in you will probably have to ream them. I bought a 27/32-29/32 adjustable reamer ($24 on internet)and the bushes fit in perfectly after a couple of light cuts.
A job I was going to leave as they were seized but not all that worn but made me anxious. So glad its all done properly and ready to go.
