Exclusive. The Crocker C4 Concept Motorcycle

The Crocker C4 Concept you admire here was designed by Daryl R. Tearne, for the Crocker Motorcycle Co. The C4 gets its name from being the 4th model in the Crocker lineup, after the “Speedway”, the “Small Tank” and finally the “Big Tank”. In conceiving the C4, the objective was to build a modern Crocker the way Al. Crocker himself would have done it if he was still with us today. Some design elements and even some parts were inspired by the original design and incorporated into the new C4. Things like a chassis design with the same original concept but a much more high tech approach. The Headlight’s styling is very similar in shape, but integrates a very modern 7-lens xenon projector lamp into the body. The single sided front fork was inspired by aircraft landing gear. By using this type of front-end setup, the front end is much more narrow and stiffer under heavy braking. By using Penske suspension, and designing rake angle adjustments in the front end, Crocker will be able to offer a custom fit for all customers.The Single sided rear swing arm has also some very unique design features. Body styling use old Crocker elements and alloy accents taken from the Big and Small Tank original models (like the alloy air intakes on the front of the tank). This concept bike will be built to order by Crocker Motorcycle Company.

    Can we know more? Size of engine? Price?

    The Crocker C4 engine size will be in the area of 1500cc
    and expected horsepower is in the 135hp range. Weight is aprox 395lbs. Crocker Motorcycle Company is currently considering a proposal from McLaren Technologies in Detroit to design engine internals. Pricing not available at this time.

    I like the thought that went into this bike. For me it shows the competitive impetus of the post world war two application of available technology to personal machines. It is not smeared over by adornments and that adds to the cafe racer/bobber look that drives the Modified Motorcycle Industry. This same type of thought went into automobiles and brought us hot rods for the various dry lake be timing associations, drag racing associations and the infancy of stock car racing.

    A big thumbs up to Crocker. I looked at their website and was unable to navigate to anything about this bike.

    Thanks, Cyril. I would like to see you design some bikes along this line of thinking. Your execution and attention to detail in projects like this would be more than refreshing at all the rallies and in print.

    Goldiron. Thank you. Several months ago I told Crocker that I would like to build my own Crockerlooking bike using their engine. I have news for all of you: in a few months the Crocker engine will be available for sale.

    Judging by the JJ radial engine bike and other “non-standard” customs of late, it looks to me like this is the way of the future. True one-off high-end scooters.

    Perhaps the OCC type scoter has seen it’s day….(?).

    La moto es sensacional. Brillante y renovadora, es quizas la moto con el mejor diseño de los últimos años. Espero que las veamos pronto en la calle, junto a maquinas como las “confederate”
    Reciban animo y un cordial saludo desde España (Islas Canarias).

    Hopefully the engine will be unit-construction with the transmission.

    I like the front-end a lot. The Honda NAS prototype had something similar but it never was built.

    looking forward to seeing more of Crocker !

    We want a good and best resolution pictures

  14. 14 Chris R Dec 19th, 2007 at 2:04 pm

    Man i really want to know a price on that.

  15. 15 Rik Jul 9th, 2008 at 11:18 pm

    Shouldn’t this be called the C5 as Crocker also made the “Scootabout” Which accounted for about 25% of the total Crocker output.

  16. 16 DRT Jul 12th, 2008 at 11:14 pm

    Good question Rik, the fact is, that Crocker only made 3 road going Motorcycles. Motorcycles not scooters. S, this is the C4.

    Was actually scaning to find a pic a Crocker engine that im told shared the late 30’s OHV top end with my V Twin BSA engine (J12/Y13) but came across this, i dont get inspired by modern bikes but i get inspired by this one. i could see alot of buyers for that in UK
