Few days back Yamaha just revealed this R1S on their US website. So at the first look we got confused, is this higher spect R1 or something different?
It turns out to be lower spect than standard R1, So whats hold back this new R1S got over standard R1. Well not too much, the S model gets steel piston connecting rods (conrods) and exhaust headers instead of titanium ones, aluminum for wheels, engine covers and sump instead of magnesium and result ? You get extra 4 kg metal over standard R1. The gear shift assist missing which comes standard on R1 but good news is despit of being lower spect, R1S gets Yamaha's top notch traction control and inertial measurement unit.
So all these factors together makes R1S cheaper than standard R1 ,but how much. In the US R1S will be $14990, which is $2000 less than standard R1, that's some good amount of saving. I've checked on Indian Yamaha site but they didn't mentioned anything about R1S.
The steel conrods on R1S makes more inertial mass which makes fractional difference in achieving top revs compare lighter conrods. but we suspect R1S might ending up producing slightly higher torque in lower rpm due to same reason!
