Wow, what a nice idle. Such a shame though... Why did they have to drop the two strokes :(. Honda made some great bikes :\.

Production bike from Honda using the EXP-2 technology= low emission 2 stroke.

Is this really the one?  My understanding was their system eliminated the popping crackle thing at idle?

Honda has tamed pre-ignition; on the EXP-2 this auto-ignition is computer controlled to enhance performance and most importantly virtually eliminate pollution. Usually thought of as a bastion of four-stroke technology, Honda's new two-stroke design promises less pollution, better fuel economy and most important, no loss in power.

Honda claims that when the ARC (Activated Radical Combustion) is engaged (from idle to about half-throttle) carbon monoxide and carbon dioxide emissions are 15 percent lower, hydrocarbons are down 80 percent and Nitrous Oxide emissions are down 90 percent compared to conventional engines. At idle and at high throttle openings, ignition is by spark plug and emissions are similar to other two strokes.
