Took the swingarm out and extracted the shaft. Top is as new. The bottom is beyond bad. I really think it is unsuitable to be put back in have to sleep it over
Didn’t see how bad it was when it was in the swingarm. It is proper shot.

That driveshaft is done. It can be replaced with a new one. The problem is the female coupler on the FD. No replacements for that except complete new FD.

I have a basket case 2005 RIII that has a fully stripped out drive shaft and coupler on the FD. The sad story is the dealer was not a trained triumph Tech. He did not know about the drive splines. He disassembled the entire bike and engine believing the no drive problem was a broken transmission. He totally missed the stripped splines. After total disassembly and inspecting the transmission, they realized their error. The fee to do this was about $800. They wanted another $5600 to reassemble and fix the stripped splines with a new drive shaft and FD. The owner took it home in pieces where it sat in his garage for years. Until his wife said, "Get it out of here". I purchased it for $1000.

Anyway, You will need to buy a new or new to you (used) driveshaft and FD. If you can, up-grade to the Roadster shaft and FD. The spline and coupler are much larger and last longer ... at least that is what they say. I purchased used ones as a set for my 230 HP 2006 RIII. After installing these on the 2006, I'll move the ones I'm taking off the 2006 onto the 2005 RIII.

This is how I got it back in 2019. Still looks like that now in my shed. I did sell a lot of the accessories and got more than my money back.
