I am big fan of Yamaha. Currently I got Yamaha R3 from chennai. R15 is the economic bike, which u can take long ride also, best bike n reasonable millage.its a best n budget bike for all.everyone can ride this bike, strictly not for people who have back pain and all. Previous version of R15 v2 for its lower back seat, but R15 looks alike as the Yamaha R3.so to confuse you can modify it n look like Yamaha R3
