At MotoSoul 2024, TVS has revealed a brand-new 300cc engine, which is called the RT-XD4.
TVS’ latest engine displaces 299c and is both liquid-cooled (for the head) and air/oil-cooled (for the crank cases). This new engine is rated for 35hp at 9,000rpm and 28.5Nm at 7,000rpm. Bore and stroke figures stand at 78mm x 62.6mm, respectively and TVS insists this is a brand-new engine. For reference, the Apache RTR 310’s 312cc motor has bore and stroke figures of 81mm x 62.1mm.
This engine is mated to a 6-speed gearbox and a slipper clutch too. It isn’t yet clear if TVS will offer a quickshifter on future models powered by the RT-XD4. This new engine has thoroughly modern architecture with features such as dual overhead camshaft, a plasma-coated cylinder and dual cooling jackets inside the cylinder. While all this is rather complex technology to explain in this story, TVS claims that the engine has a very flat torque curve, which should make riding in the real world quite effortless. The first bike to be powered by the RT-XD4 should be launching quite soon and in fact, TVS has even filed a trademark for the name Apache RTX.
