Hello guys I am back.i am sunny chauhan.i have a bajal platina bike with both 100cc and 125cc.you already know the difference of 100cc and 125cc.its all about engine capacity and mileage.both of it.i recommend you to buy a 100cc.if you are living in plain areas.if you living in hilly areas you can buy 125cc platina bike.100cc bike is not good in hilly areas.when I go to any trip in hilly areas.most of time engine noise and also engine very hot.100cc bike capacity is fine if you travel with rider and pilion .and also it gives good mileage to you.125cc bike is for hilly areas people.and all india know that it is a good bike ever.and no any vibration when you drive with only two people( including driver) .it is a very good bike .both 100cc and 125cc.100cc for plain areas people and 125cc for hilly areas people
