Once reliant for technical assistance from erstwhile partner Honda, the split made Hero MotoCorp look at new establishments for powertrains as well as R&D. Having worked with its technical partners over the past two years, Hero is finally gearing up to launch its new set of motorcycles with self-developed engines. Spied here is the new Splendor Pro motorcycle that will be employing the new 100cc single-cylinder engine that replaces the age-old 97.2cc unit originally developed by Honda.

The new engine has been developed with inputs from Hero’s new technical partners AVL, Engines Engineering and Erik Buell Racing (EBR). The engine is expected to belt out a similar 8 BHP of power and 8 Nm of torque, paired to a 4-speed gearbox. Emphasis will be on enhanced fuel efficiency that will help Hero take on the recently launched Bajaj Platina ES. Considering that the manufacturer plans to retail its bikes globally, the engines will be developed meeting global standards, which should keep quality and NVH levels in check.

Considering that the old 100cc mill was powering a range of commuters in Hero’s lineup, the new engine will also do duty on the Passion Pro, CD Delux and HF Dawn among others. There have also been reports of Hero MotoCorp working on a new 97cc bike which could be a new entry-level model in the company’s stable. With Honda taking a lead in showcasing its commuter products for the year, Hero would not want to stay behind for a long time. The Indian auto giant plans to launch its new range later this year which will include the new Passion 125, Dash and Dare scooters; and the upcoming 97cc motorcycle.
