                  It's very good and it's mainly good to do off-road on mountain. Good for single use.Its very light weight and a light weight person can also handle this types of mountain bikes. Kacha rasta ke lia bahut accha hai (it's good for under-developed road ) also if a man of 51 kg of minimum weight can also handle this bike.

                  Expensive bike
                  Good looking of road bike , price is bitt too high , u can get a 300 cc sports bike in this price range. Is it road legal , looks are great only 50 cc and , I think all ktm bikes have powerful engine, ktm and bajaj are doing best to bring all types of bikes but price segment am not sure it will have good sales

                  Ktm 50 sx costly bike
                  Good bike but on costly side this is a good bike but only for enthusiasts. I don't think this is road legal. Therefore be aware of the road safety and rules regulations before buying one. Good for stunts and popping wheelies. It is so light which makes it agile to handle. Finally it comes from ktm therefore it is reliable indeed

                  Just go for it. In this price rs 457 is best in segment. Love you Aprilia, riding experience shocked me. Power of this bike is insane. I don't think in this price any bike will close to Aprilia. Breaks are awesome, works smoothly, looks of this bike is like 1000cc bike, top speed is 200+ and this is cool.

                  Aprilia RS 457 Ownership Review
                  It is the best choice for a budget super sport bike and looks aggressive with a lot of torque and power. The twin cylinder engine is very tractable and the overall ride experience is fun! Definitely a head turner. The bike is very smooth and the engine is very responsive. The posture is a bit demanding so would avoid in traffic jams and long rides. The power is just amazing, a twist of the throttle and before you know it you are reaching triple digit speeds. This is a pure red bike and would only suggest it to those who are genuinely in need of the power upgrade and will ride the bike the way it is meant to. For beginners and clout chasers would definitely recommend to stay away from this bike.
