An online document has revealed the power figures for Yamaha’s upcoming BS6-compliant FZ, FZ-S and the YZF-R15 V3.0 models. A drop in power figures was an expected outcome of the changes made in order to make the engine meet the strict norms; the document reveals the numbers.

According to the document, the BS6 FZ and FZ-S are set to make 12.3hp at 7,250rpm, instead of 13.2hp at 8,000rpm that it currently produces. This is a drop of around 1hp and while that may not sound like a lot, it's quite significant on a 149cc motorcycle. Similarly, power on the YZF-R15 V3.0 will go down to 18.6hp at 10,000rpm, from 19.3hp at 10,000rpm. This drop of around 0.7hp will be less apparent, as the R15 is a more powerful motorcycle. The torque figures haven’t been revealed in the document though.

Most motorcycles in India are expected to witness a reduction in power figures with the modifications being made to them for BS6 compliancy. The BS6 Honda Activa 125 and the upcoming Hero Splendor iSmart make lower figures as well.

The other information revealed by the document states that the bikes’ dimensions remain unchanged.
