SP swingarms are similar to the RR but have a lip on the chain side for the captive spacer. The brake hanger is machined to also have a lip for the spacer so the rear wheel can simply slide in. There are mounts for bobbins too.

Chris just post a pic of the bike to begin with.

there's no bobbins on the swing arm so it's not an SP
