Austrian motorcycle maker, KTM has taken the wraps off their first two-stroke fuel-injected motorcycle range, the 250 EXC TPI and 300 EXC TPI. Unlike most Japanese manufacturers who have their focus on four stroke engines, KTM has developed these two-stroke machines that also satisfy the stricter emission norms. Instead of a conventional pre-mix setup with carburetted jetting in Enduro motorcycles of earlier years, the new motorcycles use Transfer Port Injection.
In the TPI or Transfer Port Injection system, the engine is claimed to ride smoother and have a much better fuel efficiency when compared to the conventional setup. This system is regulated by a new engine management system which sprays the exact amount of fuel into the ports depending on the throttle input, largely similar to what happens in a fuel-injected engine. In order to maintain a proper amount of lubrication, a separate injector sprays tiny amounts of oil with the air intake system. The new ECU (Engine Control Unit) utilises a number of sensors and reading to ensure a proper firing of the fuel in the engine.
Both models are equipped with state-of-the-art hardware which includes fully adjustable WP suspension, Brembo brakes, a lightweight steel alloy double cradle chassis as well as off-road tyres. Here is the best part! These motorcycles are compliant with the existing Euro 4 emission norms thereby making it possible for production. However, both the two-stroke motorcycles are not road legal and hence cannot be registered for public roads. That said, for the petrolhead in you who craves off-road adventure rather than traveling over tarmac, the KTM 250 EXC TPI and 300 EXC TPI will be available after June in European markets.
Prices of the motorcycles have not been announced yet, however, KTM is expected to announce a competitive retail tag. What is most interesting with these two motorcycles is the fact that the Austrian manufacturer has broken the stereotype of two-stroke engines being more harmful to the environment. KTM will also roll out a road legal version based on these models later.
It is highly unlikely that any of these models will reach Indian showrooms as the demand for such vehicles in the country is limited to a niche audience. Even then if the company plans to introduce them in India, it will only be in limited numbers. However, if these do come to India, it'll be a phoenix rise for two-strokes in India after the demise of the iconic Yamaha RD 350 and RX 100. We can only hope for now that KTM gets some units of these motorcycles in India, although they might be priced quite high due to being direct imports. More details will be clear as the price announcement happens in June this year.
