HI
I have had a 49cc china girl for the past year and have clocked just over 5000km on it and it just died on me. So for xmas i'm getting a new bike and a new motor and i dont know what to get, a 49cc or a 69cc. I do go up a lot of hills and my 49cc china girl had a little trouble getting up some of them, so i am thinking of getting a 70cc.
What do you think I should get? and what is the difference in fuel, how much more does the 69cc drink.


Thanks

I would think you can still get 120-150 easy with the 70cc. All mine have.

The 70cc has more torque, which is what you are after.

Never rode a 50cc. the 70cc has lots of torque and to me likes lower rpm. I have it geared with the shift kit to cruise at 25 at just above idle rpm.
