Yamaha launched the rear disc brake variant of its popular naked motorcycle, the FZ-S FI, in January this year. Initially available only in Armada Blue, Yamaha now has introduced two new colour options - Matte Green and Darknight - for the 150cc motorcycle. Interestingly, the two new colour options are priced at a premium of Rs 1,000 over the existing Armada Blue paint scheme, which retails for Rs 86,042 (ex-showroom Delhi).
