I have a moots which came with S-Works Turbo 24mm.
The bike has been siting in my garage for almost 2 years and am considering going with GP 4000 ll 25mm

I am not familiar with the S works although I do have GP on my other bike.

Any comments would be appreciated

Both are fine. If you were buying new I'd probably lean toward the gp4000's because they're better known with a good reputation, but since you already had the specialized I'd just use them until they wear out. Specialized makes decent tires nowadays from what I've read.

I've been using S Works Turbo tires for over a year. They are a bit more robust than the Conti's but still quite light. I have one on the back now with about 3500 miles with maybe another 1000 miles left to go and they are fairly smooth. I have no real complaints against conti 4000S tires but the side walls are weaker. I once rode over a small stone with the Conti, that shot up in the air, spinning like mad, puncturing the sidewall. Something like this would not likely happen for 100 years but it did give me pause.
