Mass market model record: appears in mongoose.com first-party captures 2017 to 2026 and is listed on the live site in 2026-09. Years before 2019 come from the old mongoose.com catalog listings, which kept older models listed for years, so the true selling window may be shorter. The first-year catalog showed more than one price, so no launch price is recorded. Components are from the live mongoose.com page. Factory colors: Red, Grey.
