congrats brother MashAllah nice purchase please share the pictures with us. Zero meter bikes are always hard and tuff. just keep doing your engine running. change 1st engine oil on first 300kms. right now you might feel the shocks are too hard. near 400 to 500km. you will start feeling the bike is getting soft and smooth.
engine heavy nai hota bike ki chassis heavy hoti ha due to chassis weight we feel the bike is heavy/low.
all engine and other parts are new in the bike. with the passage of time they will get soft & smooth. nothing to worry about. Don't forget to give sadqa of your bike even you can give 10 Rs. depends on your pocket
