I have a Corbin riders saddle,, and am wondering about improving on my pillions oem seat. But it does not seem that Corbin currently lists a matching rear saddle. They do list the smuggler compartment,, which is a nice option for solo riding,, although it is super pricey. Am I missing something ?? I did think I saw some modified rear oem seats on a few ST 13 bikes that attended Onstoc. Perhaps they are a Spencerized product ?? Anyone know ?? thx,, Cat'
