Yup, 530 102 link. I'd recommend an x-ring over and o-ring. It's a better design and lasts a bit longer. I'd also say that you can safely go with a clip rear link instead of a riveted one if that's an option. That way you don't need a riveting tool. I put rivet links on my sport bikes, they're a bit stronger and more secure, but I went with a clip on my RE and no problems.
