exactly which legislation is it?
back 4 years ago it was euro 4 which came and went, then euro 5 is being rolled out and still no change.
I read over the euro emmissions targets and didnt see anything that really applied that would make a two stroke offroad vehicle require DFI.
If you can find which euro emmissions target will cause two strokes to start running EFI/DFI then let me know because I would be interested to see if someone else can pinpoint an exact time point where 2Ts will HAVE to run clean.
I don't know exactly - I'm no member of the European Parliament nor part of KTMs emissions / legislation / rules matching development team. Apparently, the 'goal posts' keep moving, but they are very close to being brought in force.
Firstly, Euro 3 was the most prominent one that effected 2ts - that's where you saw some 2t bikes in Europe coming with differrent pipes with catalysers in them, or, for example catalysers in the header pipe - I got caught out prepping a EXC125 and 200 here that had those in the pipe - Euro market bikes, diverted to OZ.
Euro 5 was reputed, initially to be mostly pertaining to Diesels, from my recollection. Then , various articles began to bring it into discussion with 2 strokes - particulate matter, high petro - chemical emissions are very much part of 2ts problems.
Sit back and be ignorant all you want people, legislation, that will force 2T Clean Tech(s) - do read that, please - are imminent. It will be on Road Going bikes. The European EXCs - for most owners in Europe, and here in OZ and Many countries, Road Registration Is a requirement.
So, some clean tech, be it EFI, DFI, things like Smart Carbs, some with trapping valves, AST, FAST and many other techs to clean them up, are comming. The MXers /Off Roaders that don't require it, almost certainly won't have it - KTM have said this themselves, a few times. Go in search of what KTM have said. Either it was last year, or the year befores model introduction conference at Munich Airport that one of the heads of KTM spoke about these points - it's all on video, that you can find and watch.
But, you never know, it may work so well / they ( companies
- not just KTM) may want to ammortize the costs quicker, by much higher levels of production. Companies, especially KTM, have had a long time to develop their various Techs. And / or Other companies new 2ts / 2t Techs will force there hand, that whatever KTM have, will be fitted to more than just Road going 2ts.
If you think that Forced by Legislation clean tech is a long way away, you've your head in the sand, people.
KTM /Others, have just been milking the high profits from their *barely changed in decades 2ts*, for as long as they can. It's the way to do business. And I've written that, many times. It might pay you to read, And comprehend, what is written. If they - KTM or any other company - Don't produce bikes that work well, whilst meeting the emissions levels that are required, they won't get sales. I guess they could sit back, and Not produce Road Legal 2ts for a few years, whilst others did, and "learn", but they'd be conceding a major part of the 2t market to other companies
. This is All About Legislation Pertaining To Road Legal 2 Strokes. I emphasise that, to help with peoples comprehension of what I am addressing in this discussion.
Reverse Cylinder 450s?
What are you on about , Jeram?
Reverse Cylinder 2ts, like the Ossa - certainly I've referred to that. And TZs /TZRs. And , probably the 'Tularis / Tul-Aris' - you know, Jeram, the reverse cylinder, Polaris based 2t twin Road Racer done by Dr Robin Tuluie? Though, it's old, and just has carbs at the front :
There are a lot of articles about Tuluies' bike you can find on the web, if any are interested.
Then of course, my recent suggestion of getting a Quaife (sp?) , or other gearbox, to hook up to that other 2t twin shown - though, that was not a reverse cylinder 2t, to my recollection - could be wrong on that, though.
A 400cc 2t, will probably be the near perfect modern Dirt Bike engine. Small, light, with plenty of torque and power, whilst being under little 'strain' producing that torque and HP. F*** the CV Transmission idea, though. Mind you, Honda's "dog leg" system, is bloody amazing. That's a "Auto / CV" trans I'd like to try.
