Technological advances made in the past 15 years to catalysts and engines can now significantly reduce motorcycle emissions. As a result, the ARB has adopted a new set of standards that will apply to 280cc and larger motorcycles starting in the 2004 model year with additional reductions required in the 2008 model year. HC and oxides of nitrogen (NOx, the other of two important smog-forming compounds) emissions are combined into a single new standard that will give manufacturers additional flexibility to lower emissions and provide motorcycles that meet consumer needs. HC plus N0x emissions is required to be reduced to 1.4 g/km for the 2004 model year and 0.8 g/km for the 2008 model year. This represents a significant reduction over the current standards while being feasible and cost effective. It is important to note that these actions will not affect motorcycles produced prior to the 2004 model year, nor require the retrofitting of existing motorcycles to meet new standards. The ARB is also discussing with manufacturers a proposal to offer an incentive plan encouraging the introduction of cleaner motorcycles prior to the 2008 model year.
Electronic motorcycles are an excellent way to "go green" lowering emissions to near-zero and cost to pennies per mile. Quantya manufactures a line of electronic motorcycles, as does Zero Motorcycles, Vectrix Global, Hero Eco Ltd., Brammo, Electric Motorsport, Mavizen, and Mission Motors.
No. They haven't any emissions controls, in most cases. Though if riders are spending less money on gasoline what does that say about the human environment? Less energy struggle?

Do motorcycles have an alternator.
No. Motorcycles are dangerous than cars.
Homeowner's insurance WILL NOT cover stolen motorcycles. Motorcycles is an automobile. Sorry!
star motorcycles is just a line of motorcycles made by Yamaha
