Honda #08R71-MLA-A00 - frame only, no pad. Installed for a short time but like new. No hardware except spacers - 1100T models can just reuse OE bolts, no other parts needed; "non-T" models may require longer bolts. Fits all years but is NOT compatible with tall passenger seats like the 2025+ "comfort" seat (see 2" taller frame #08R78-MLA-AA0). High enough for most aftermarket seats except maybe Corbin dual. 

PAD sold separately - see eBay. Compatible with 2021-24 black backrest pad 08R79-MLA-A00, 2025+ black pad 08R80-MLA-AA0ZB, and 2025+ brown pad 08R80-MLA-AA0ZA. They are all the same other than color.
