Spudrider do i have to change my front rim to 19? i feel like my bike's front is lower then it should be.

No, you don't need to change the front rim. Our RX3 motorcycles in the United States have a 3.00-17 rear rim, along with an 18-inch front tire, and we aren't having any such problems.

If the front wheel is bouncing up and down, I suggest you verify whether or not the rim is 'true.' The rim must be symmetrical both radially, and laterally, in both the X-axis and Y-axis. If the wheel is not 'true' (symmetric) in both axes, the wheel will bounce.

I also suggest you check the front tire for unusual wear patterns.

If the front wheel only bounces while braking, I suggest you install another front brake rotor.
