Stephan Pierer, Ktm, revealed that Ktm has developed all new 500 and 800 c.c. parallel twin engines. They will power new bikes coming within the following three years. 
Actually there will be a new range based on a common platform, following the Duke/RC concept. An adventure and a off-road bike will be introduced in the future. The bikes will probably be manufactured in India, hence their price very competitive.
