Well, two stroke trailie bikes are a huge hit around here. People are actually reverting to them after experiencing the relatively high running (and repair) costs of the modern four strokes.
But I do not see much future for them. The writer is overenthusiastic to say the least.
True, they can be made as clean as a four stroke using various fuel injection technologies but at what's the point? Lotus made a 2000cc two stroke car engine a few years ago. It was clean (it complied with Euro 4 emission regulation), made good power and had more than good fuel consumption. Yet they still use Toyota engines on their cars. Why? Because it's much cheaper, end of story.
Also look at reliability: true, a two stroke can be rebuilt at a fraction of a four stroke but when's the last time you heard about a Fireblade or R1 engine seize? Modern four strokes may be complex but are incredibly reliable. especially when regularly and properly serviced.
Also the present license legislation in Europe completely killed off the 125 and 250cc classes, which were the main driving stimulus behind high performances road-going two strokes.
No, if I see a future for two strokes is in niche applications such as dirt bikes. Too bad Honda will have them outlawed sooner or later...
