As is evident, the performance numbers are a close match. However, the new RT-XD4 engine could deliver a better overall performance with its advanced architecture. TVS has stated that the new engine has highly linear torque characteristics. In essence, users can expect a seamless ride experience with the new engine.
While not officially announced, it is possible that the new RT-XD4 engine could be lightweight. If that’s true, a higher power-to-weight ratio can be achieved. Another possibility is improved fuel efficiency. Achieving compliance with upcoming stricter emission norms could also become easier with the new RT-XD4 engine. From a business perspective, the new engine could have a lower production cost. Capital expenditure related to design and development will be adjusted over the long term.
Which TVS bikes will use the new RT-XD4 engine?
TVS has not revealed when the new RT-XD4 engine will reach the stage of commercial production. However, we do know that TVS has trademarked a new name – TVS Apache RTX. Spy shots have also revealed a blurred image of a new 300cc ADV bike being tested. This could be the first bike to get the new RT-XD4 engine. Reports also reveal that testing of the new bike is already in the final stages. And launch could take place around mid-2025. TVS already has the RTR 310 streetfighter and Apache RR 310 fully faired bikes. A new ADV bike will add more depth to TVS Motor’s 300cc portfolio. More
