KTMs are expensive motorcycles, but it appears that they are putting much of their profits into R&D. -They will be selling a fuel injected two stroke enduro in the US by the end of 2017. Fuel economy is said to increase and emissions decrease dramatically. -If successful, we may once again be buying big, new two stroke bikes like the Yamaha RDs and Kawasaki H triples on the street.

This is a bit sad since Aprilia had been making fuel injected 2 stokes since 2001 and through about 2014.
Kudos to KTM and their decade long effort to adapt more off the shelf automotive style fuel injection components to a 2 stroke bike.

Can't imagine how an oil burner can make it through new emissions regulations, perhaps they will have to develop a "clean" oil that won't affect emissions.

Technically a 4 stroke can end up useing more oil compared to a modern 2 stroke. They both have oil coat the cylinder and burn off at every combustion stroke with the 4 stroke also fogging crankase oil out the purge tube which is why they put a system to reclaim that vapor and burn it out the exhaust. |

Pining for the good old 2 stroke days on my part (DT 250, RD200, etc), I suppose.

I believe in California the only 2 stroke you can get is a used one if you can find a decent one or new aprilia 50cc |

I believe in California the only 2 stroke you can get is a used one if you can find a decent one or new aprilia 50cc Piaggio squashed the Direct Injected Aprilia 2 stroke. Outperformed by far their own 50cc bikes so they only allow them the make a 50cc 4 stroke Motard Scooter now for US distribution. Too bad since Aprilia was the leader fover a decade in small fuel injected 2 strokes even though their design was a cam style pump and not sequenced by an ECU. There may still be some new 2014 DiTech bikes hidden away in warehouses but mostly these little gems will be Craigslist finds. |
