It checks the bike is real first. If it isn't, it says so instead of guessing. If it is, it resolves the job to the part's actual spec and crosses on the spec to what's in stock, so a discontinued OEM part on an orphan bike still comes back with an answer.
Prototype seeded with real, verified data for the Honda CBR600F Hurricane fork rebuild. Three behaviors: reject a bike that does not exist, solve a real one by spec, and admit where its own data ends instead of making something up. Type freely - it reads shorthand.
