I ride a motorcycle every day and have for 40 years. I live in Arizona so motorcycles can be much more than a toy, it is my transportation.
Friday I took delivery of a 2014 Honda CBR1000RR SP. This bike is unbelievable. 400 pounds and 155 HP. Full Ohlins Race suspension, Brembo Monoblock Brakes, and an engine built by HRC (Honda Racing Company) that is blueprinted and balanced from the factory. It is also a "monoposto", no passengers, maximum rider weight is 200 pounds. The bike has a mileage computer on it, even new and tight, it gets 55 MPG at 65 MPH, sitting straight up. If I go into a full tuck it is 63 MPG at 65 MPH.
Not only is the gas mileage very good but it is very exciting to ride. It would be a half a million dollar super car to have this performance.
This is not however a cheap machine to operate. The bike is $17,000. Tires which are Honda spec tires built by Pirelli will only go about 3,000 miles and are $500.00 a pair.
Nothing makes me feel like I feel when riding a bike in the Arizona mountains on a sunny Saturday morning. My brothers Prius gets the same gas mileage, but the experience is not quit the same.
