At MotoSoul 2024, TVS has revealed a brand-new 300cc engine, which is called the RT-XD4.
New TVS 300cc engine details
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.
With this sort of performance, upcoming TVS bikes powered by this engine will sit in a no man's land in between the KTM-Husqvarna 250s, Honda CB300R on one end and the Triumph, Bajaj and Royal Enfield on the other. The only comparable bike is actually TVS' own Apache RTR 310 which makes 35.6hp and 28.7Nm. It will be interesting to see how TVS positions the new 300cc model in its range in comparison to the two 310s it also has in its portfolio.
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.
