Last Call: V4 Whom The Bell Tolls

Motus, the Alabama-based boutique motorcycle manufacturer, is broke and recently ceased production. The good news is that efforts are underway to keep the SBC-based V4 powerplant available as a crate motor for kit cars, engine swaps, and motorsports applications.
Conversation Starter: What vehicle is crying out for a Motus V4 the loudest? Talk amongst yourselves.

    That would fit nicely in my ’84 Innocenti (classic Mini sized)

      Oh my, would it.

      Fun fact: Innocenti actually developed, and was close to launch, a Mini with a Guzzi V-Twin. The project was later abandoned.

        Interesting that it is air cooled. I didn’t know that.

      This was the answer I was thinking of as well.

    The Sky already sort of looked like a pint-sized Corvette, why not give it a pint-sized Corvette engine?

      Because a full-sized Corvette engine will fit?
      Although I would love to confuse people with custom badges that say “LS/2”.

        The V4 is something like 300 lb lighter than an LS though – 150 lb. That’s going to make a difference. Too bad they are so expensive.

    Thats a shame that I only heard of them now. The bikes don’t look half bad

      True, but they’re certainly not cheap!!

    Put one into each inline 4 car advertised on Craigslist as a V4.
    Two of them, in a V8-6-4 Cadillac. It would probably operate only as a V8-4, but middle children are fairly unimportant and high maintenance anyway.

    It’s like the anti-Hartley. Where the Hartley V8 is built by doubling a motorcycle engine for use in automotive applications, the Motus V4 is built by halving an automotive engine for use in motorcycle applications.
    Both are awesome.

    If there’s a Goldwing-style prop shaft output at the back of the trans, rather than a chain drive sprocket on the side, I’d love to put one in Project Justy. If this engine I rebuilt ever lets go again, it’ll need motorcycle power (and will be RWD).

      Would a 3 cylinder 2-stroke snowmobile engine work?

        The main advantage of sourcing the engine & drivetrain from a Goldwing or larger bike is that the transmission should be durable enough to haul around the weight of a car. I don’t think a snowmobile drive belt could handle pushing around 1800 lbs. worth of Justy reliably. A Goldwing engine is torquey and low-revving, practical for driving around town.
        Also: 2-stroke engines sound like ass, especially droning at constant revs because of a CVT.

        Clearly I’ve spent too much time thinking about this.

    A Subaru

    Put one of these on the front of the crank in the engine bay of any originally LS equipped vehicle.

    It’s funny, when I first saw the picture I thought it was a a Honda ST1300 powertrain. so maybe a Morgan style 3 wheeler would be a good host for this
