DI would just be a gadget to increase selling price and raise part replacement costs, dealer service frequency, and BS the masses into thinking they cleaned up the emissions on a bike, that when jetted properly, run cleaner than 4 strokes. They have the masses thinking if you can see the exhaust it's bad. Truth be told, the smoke you see from a 2 stroke is simply moisture from the oil, it is too dense to rise into the atmosphere, is only present during warm up, if the bike is jetted properly, and has less Co, than a fourstroke. And get this, if you are using castor or bean oil, is not carcinogenic, it is actually good for the earth,
.
This is the same type of scapegoating, misrepresentation, bold face lying, and typical Corporate Snow(shit) Storm, that is responsible for a certain plant
, that can produce 100s of products such as fuel, oil, paper, plastic, cloth and other textiles, has medicinal properties, makes you feel good, is a bi annually renewable resource, and has been growing naturally on this planet long before our viral asses showed up and started f'n it up.
And it is true, you can make a 2 stroke run smooth through it's entire range of throttle just like a four stroke. It's called a fly wheel weight.
The reason that the jap manufacturers build them to "hit" in a certain part of throttle range is because they are purpose built for moto x and that is were they should be ridden.
The problem lies in that
1. the majority does not posses the talent or ability to ride in that part of the power.
2. the owner is using said machine for purpose other than MX or SX
This is where Honda was with it's last run of dueces seeming to be lack luster, knowing that the owner would tune it to thier liking with the abundance of after market products, they built a solid platform for which to start. The yamaha dueces are the same way, smooth power without alot of rip out your arm hits in the power range.
