Q. Since Bullet Standard 350 is launched with single channel ABS, I am now confused as to which one to go for - Bullet Standard 350 cc or Bullet Standard 500 cc - considering 500 cc has more safety features? My use is mostly city commute and looking for a bike which is sturdy, reliable and comfortable from the above 2 bikes.

That's true .... standard 500 is having more safety features... standard 500 is having a little bit more power and massive torque...rare tire of 500 is also bigger... but vibrations are also on higher side compared to 350 cc....if you are not worried about the vibrations, 500cc is the best choice...and since you have chosen bullet, average won't be the issue for you either way

YOU CAN GO FOR 350 CC IF YOU ARE RIDING IN CITY MOST OF THE TIME. IT WILL GIVE MORE MILAGE AS PER MY THINKING AND YOU WOULD GET VERY RARE CHANCE IN CITY TO DRIVE IN TOP GEAR. SINCE 500 CC IS MORE POWER FULL AND WHEN I RIODE IN CITY FEEL ANNOYED DUE TO FREQUENTLY GEAR CHANGE. BUT ON HIGHWAY OR HILL DRIVE 500CC IS PERFECT DELIGHT WITH LOAD OR WITHOUT LOAD.

Bullet 500 and 350 both are excellent machines. If you looking to use only the bike only for city and short commutes then 350 is the best suited for you. But Bullet 500 is good for City riding and an excellent for touring too, you can get the best of both. So consider this factor before buying mate.
