Concept motorcycle : The Crocker C4

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.

Tesla Motors Lithium Ioned up.

Now that Tesla Motors has resurrected the electric car in screeching sports car form, it's the turn of the motorbike to get all Lithium Ioned up. While it's not the first electric motorcycle, it is possibly the most rough and ready design: if you can afford the $15,000 odd fee for a custom modification, a team at the Electric Motorsport shop in Oakland will take out the nasty engine in your ride and replace it with an array of Lithium Ion batteries. As a prototype, the company created a fully electric version of the Yamaha R1 which has a top speed of 100MPH, a range of 100 miles, does 0-60 in 3 seconds, and looks pretty damn ugly to tell the truth. Ya' see, the number of brick sized Lithium Ion batteries required to eke out this level of performance is 28, which have to fit all willy nilly underneath the bike. Fortunately, the company hopes to produce a more refined production model, as well as a cheaper design with less advanced performance.
