The '21 Gsxr1000R Showa rear shock is in!
This is a Huge win, and for cheap.
This '21 rear shock looks and feels brand new!
And for $147, plus $140 for Soupy's +2"/-2" adjustable on bike lower links, kept the budget in check.
This adapter was of course free, but would be around a couple hundred to pay a machinist for a couple hours, setup and run time plus a small piece of aluminum round bar.
Regardless, for the money, this will transform the handling of an '03, along with RaceTech springs and Gold valves for the front, which with seals and oil was still under $400.
So I will be under $700 in a very well performing full suspension upgrade.
I am very grateful that my Dad is still able to make parts for my bikes, and that he still enjoys making things.
The custom lower clevis adapter threaded on, and the '03 clevis went on to the '21 shock and spring just the same as the stock '21 clevis did.
The '03 Gsxr1k spring comes off the shock just by loosening the 2 upper nuts/lock rings, which is just like the Gen1, 2, and 3 Busa.
However the '17-'24 Gsxr1000R Showa shock requires a spring compressor to remove or install it.
This Tusk spring compressor that I have has clear plastic guards to keep from scratching the spring, and makes the whole job very easy, and the spring doesn't need compressed very much.
The whole swap only took a few minutes.
I rolled the bike off of the table to check the ride height, which is only about a half inch taller.
I put the shock in on the stock lower links, then installed the Soupys links at stock length.
I will adjust the ride height after the bike is ready to test ride, and will get the whole suspension dialed in accordingly.
I have it back on the table again, but swapped out the front wheel chock for the front forklift/triple-clamp stand, so I can start on the forks next.
The shock needs adjusted obviously, but it felt great rolling the bike around.
The compression and rebound feel like a brand new bike, as hoped and expected!
The old '03 shock was tired, and there is no comparison as to how much better the new shock is.
I really like the black and gold color of the new shock too, as it matches the bike, and I prefer it's look and design compared to old silver with a yellow spring.
