We are fairly confident that our kits will fit Spirits (VT1100c) as far back as 1987. We are 100% sure that the transition is incredible. Adding our seat and rear fender kits add a fantastic face lift to those mundane stock bikes. Riding them is pure joy! They have power galore and a smooth suspension. You can easily transform your bike in a weekend. Paint and other frills will take a bit longer. Honda made a ton of these bikes so finding one cheap and fast should be easy. Let us know when you are ready to have the coolest ride out there. And you won’t have to rob the bank in order to pay for your new toy!
