1999 VT1100C2 A. C. E.
EXACTLY what I'd expect. Other than the engine (single-pin-crank in ACE vs dual-pin-crank in Spirit), rear brake and routing*/attachment of exhaust they're the same bike with cosmetic changes for differentiation. Compare. Honda has always liked using common parts. Other than the Spirit pillion backrest, the seats are basically the same.I have the 1100 spirit. I got a used ACE rear fender on eBay and it bolted on perfectly. I'm even using the seat from the old spirit fender. The factory 2 piece seat, a Corbin one piece seat, and a Mustang tourer seat all work perfectly.
* Front exhaust pipe on Spirit goes over footpeg; on ACE pipe goes under. Rear pipes follow different line across side cover.
