Company History
Sinnis built a loyal UK following by pairing well-specced small motorcycles with local support—spares on the shelf, phone-answering dealers, and honest manuals. Early offerings focused on 125 cc commuters; later models added small-ADV and retro styles with ABS/CBS, EFI, and improved coatings for British weather. The brand’s real contribution is predictability for new riders: approachable seat heights, tidy fueling, and customer service that demystifies first ownership. Sinnis also nurtures community through ride-outs and training partners, treating the purchase as the start of a relationship. Historically, Sinnis exemplifies how a distributor can turn global platforms into trustworthy local products by sweating aftersales details and spec choices that match real UK roads and licensing.
