I wouldn't think a Harley would be considered a crotch rocket, but they are fast. Next, most import sport bikes have a whine noise, super fast, something I could consider a crotch rocket.</p> <p>What about the v-twin sport bikes, would those be considered crotch rockets just like an inline sport bike? </p> http://the-grayline.com/forum/topic/motorcycles-pollute-more-than-suvs-tiny-info#post-86 Sat, 23 May 2009 09:36:22 +0000 tom2000 86@http://the-grayline.com/forum/ <p>This story is about emissions. More specifically, it’s about the surprising level of emissions spewing from on-road motorcycles and scooters. In California, such bikes make up 3.6 percent of registered vehicles and 1 percent of vehicle miles traveled, yet they account for 10 percent of passenger vehicles’ smog-forming emissions in the state.</p> <p>In fact, the average motorbike is about 10 times more polluting per mile than a passenger car, light truck or SUV, according to a California Air Resources Board comparison of emissions-compliant vehicles.</p> <p>I’ve been hearing from an increasing number of readers who want to know if two-wheelers, which consume far less fuel, are also smog busters. Because scientific questions tend to come with complicated answers, I thought I would do my best to explain what pollutants a gas-powered motorbike emits and why.</p> <p>Tom</p> <p><a href="http://www.bikenut.com.au/motorcycle-transport-motorbike-transport-services.php">motorcycle transport</a> </p>
