I found myself wondering what bike Prince rode in Purple Rain, and because it’s 2025 and the Internet exists, it’s easy to find out. The answer was kinda surprising, and kinda not.

What’s not surprising: It was Japanese. In 1985, Harley wasn’t really something most people would’ve noticed or wanted. The investor group led by Willie Davidson had only closed on the purchase from AMF a few years prior, so their recovery was really still a work in progress. The idea of Harley being “back” didn’t really come up until ’90. So: Japan still pretty much owned motorcycling in the US at that time.

What is surprising: What the actual bike was. In the film it’s a bike with a pretty big purple fairing, which gives it the IMPRESSION of being a large machine. Except we all NOW understand that Prince Rogers Nelson was a tiny, tiny man — about 5′ 2″.

Now, in 1984 we didn’t know this. I mean, he obviously wasn’t six foot four or whatever, but exactly how far to the left of the bell curve he fell was definitely not widely understood until much later.

Crucial to maintaining the illusion that one could not steal Prince by stuffing him into a moderate sized dufflebag was avoiding situations where it would be obvious the dude was crazy short, so clearly the producers were not going to put him on, say, a giant Kawasaki like the guys from CHIPS were riding. Having our hero and romantic lead not be able to flat-foot his moto would’ve been a really dumb idea.

So turns out: it’s a heavily customized but very small 1981 Honda CM400A. The big purple fairing was likely made by Honda customization shop Vetter, who were responsible for the original Gold Wing fairings (which were initially only an aftermarket product).

As the name suggests, it’s a 400cc bike. The parallel twin engine made about 27hp, and Honda insists it was technically capable of 85MPH. Even with a tiny, iconic musician driving, that seems optimistic. OTOH, it was 1985, and the 55MPH limit was still the law nationwide. I know from experience that 20HP will handle a double-nickel without complaint, and in the movie Prince uses the bike around town, not for a road trip to Sturgis. “The Kid” in the film is also not rich; a bike like this would’ve been easy to afford, and got excellent mileage to boot.

MORE interesting, though, is that it was equipped with a Hondamatic transmission, not a traditional motorcycle transmission. The rider didn’t have to clutch to shift at all, which is weird as hell. Predictably, the Hondamatic didn’t last long — they were gone by ’83. Interestingly, though, many modern Honda models are available with a true automatic transmission called the DCT. These bikes don’t even HAVE a clutch lever, which is important because it makes it easier for the rest of us to make fun of them. :)
