[edit] KTM two-stroke development
Since the major rule changes in Motocross to make 4-stroke bikes more competitive in motocross and being given a 125 cc 2-stroke to 250 cc 4-stroke advantage the cheaper, simpler 2-stroke bikes have been dying out.
Since other manufacturers have decided to discontinue their 2-stroke models, KTM has continued with creating and improving their 2 stroke models and taking up a very high proportion of the 2-stroke bike market.
KTM has also created a new 2-stroke MX bike with 144 cc to comply with the 2008 AMA motocross class changes. This change has been made to bring back the 2-stroke bikes to encourage more entry to the market as the 2 stroke bikes are cheaper to maintain and repair than the expensive 4-stroke bikes.
Environmental agencies have tried to remove 2-stroke machines because they produce more pollution than 4-strokes. However with newer advances in technology 2-strokes have begun to burn cleaner and pass green sticker standards.
In recent interviews KTM has revealed that they will continue to produce and improve 2-stroke bikes and have already begun looking at EFI (Electronic Fuel Injection). EFI will benefit the 2 stroke bikes because they will become more fuel efficient and will also produce less waste.
