Harley-Davidson HQ is in Milwaukee WI — Hilton properties in that market encounter HD employees regularly. Consumer brand manufacturing codes are among the lowest enforcement categories at Hilton.

"Bosch code 315000125 is an industrial-sector code. A live booking test found the Bosch Hilton rate "not available" during testing periods. Codes that rarely resolve to a live rate are also rarely verified — you cannot be caught for a rate that doesn't apply. When it does resolve, Bosch is an industrial-sector code similar to BASF and Siemens, which cluster in the low-enforcement tier at Hilton."
