The B91 Wraith from Confederate Motor Company is a $50,000 motorcycle with a carbon-fiber frame and a molded carbon-fiber fuel container placed under the engine. The Dodge's Tomahawk is not even a motorcycle in the strictest definition. To handle the massive V10 Viper engine, Tomahawk designers had to add two more wheels. They also had to move the gas tank to the front fender to shield it from the engine's heat.
Condederate 公司制造的 B91 Wraith 摩托车车架和油箱均为碳纤维制作,售价五万美刀。Dodge公司的Tomahawk看起来甚至不符合摩托车的的定义,由于采用了V10发动机,设计者不得不将轮子增加为双轮,同时油箱移到前挡泥板处,以避免发动机产生的热量。
