By the way every yamaha bike is a very good bike in performance , handling or in money investment .
But Yamaha YZF R15 S is one of the yamaha bike which I will not recommend to my friend because the on road price of yamaha YFZ R 15 S in under 150000 Rs and Yamaha YZF R15 S is only 150 cc bike so pickup and handling is too worst so Of you wanna but this bike so yamaha fz25 may be a batter choice or you can buy KTM Duke 200 . Or you also go for pulse 200 rs .
They all bikes have high performance than Yamaha YFZ R15 S .
Yamaha FZ25 is the most suitable bike for every bike lover .
Even I am also using Yamaha fz25 so I will recommend yamaha fz25 for every one
Thank you friends .
