Hi fellows. I have mondial rx3i evo (zongshen rx3 sold under this brand) in Turkey. My problem is i cannot exceed my speed over 120 km on the sixth gear! No problem up to 110 km speed per hr on the clock. But at most i have seen 120 km per hr on the sixth gear, and the rev will never exceed 7400 rpm.

Model of my zong is 2016. It has some differences than that of 2015 version sold in Turkey. For example, front wheel is 19" (18" for 2015) and the rear 17" (15" in 2015) in the 2016 version of our zong rx3.

I have this bike for more than one year and total km is over 10 k on the clock. Valve clearences checked and adjusted. No other problem. Normally i have expected 135 km per hr (84 miles per hr) speed but never got this so far.

What could be the reason? Any idea? Thanks fellows.
