I would like to know more about Yamaha R15 V1 and V2
The most suitable bike for you would be the Yamaha SZ-RR version 2.0. It comes with an easy city riding dynamics and a detuned 149 cc FZ engine. If you are comfortable with a faired bike, which may be difficult to handle in dense traffic conditions, the R15 would also be a very good option. The version 1.0 was discontinued a long time ago, making the possibility for version 2.0 currently. It gets a great 149.8 cc engine producing 16.8 BHP and 15 NM of torque. It handles excellently on highways and race tracks, thanks to its MotoGP inspired deltabox frame and aluminium swingarm. It gets a 6-speed gearbox and comes with a disc brake for front as well as rear wheel. The seat height on both the bikes do not have much difference but the sitting positions on both are highly different from each other. You can get the R15 v2.0 for INR 1,14,241.
