KTM motorcycles have currently gained the title to have the best power to weight ratio in the segment.  The engines on the KTM machines are the most powerful units in the segment. Internationally, KTM has several engines in their portfolio but we will be specifically looking at the KTM India’s portfolio. Currently, the manufacturer has five engines in total. Let’s see what technical specifications these engines do offer.

KTM 125

KTM 125 Duke

The 125 cc engine is the smallest and least powerful engine in the entire KTM portfolio. The engine is a 124.71 cc single-cylinder, fuel-injected, liquid-cooled unit. It produces around 14.5 bhp max power and 12 Nm of peak torque. The engine is mated with the six-speed gearbox. When compared to other 125 cc motorcycles it has a significant bump in power.

The power output is somewhat similar to the 150-160 cc air-cooled motorcycles available in the country, which is quite astonishing. This being a 125 cc engine still has the capacity to reach 120 km/h but at that point the engine feels very stressed. This is one of the highest mileage KTM engines giving almost 46.92 km/l.

  • In the early 70’s Triumph had winning bikes on the AMA Flat track series ever since British bikes were reduced to 500cc twins. When the rules were changed to 750cc overhead cams etc. Triumph came out with a shorter stroke, large piston model that made Triumphs very fast for a year or so. They showed up at races and won, going away.
