Some good reading on the KTM TPI models by the guys at Rust Magazine:
But what really excites, the reason we should be impressed, is the packaging. Ktm have made an emissions compliant two-stroke racer that retains the simplicity that we know and love about two-strokes. the complexity lies hidden, safe and out of harm’s way in the ems (engine management) unit, all the other components and assemblies (throttle bodies, injectors, pumps and sensors) are kept simple, robust and easy to work on. this is the KIss principle executed to perfection; it’s why Ktm have taken the best part of 14 years to come to the market with the technology.
