Its not the "Ride Height" which is adjustable. Its the "Rear shock absorbers", adjusting them will stiffen or loosen it. (The best setting is to keep it in the middle ... there are three points, if i am not mistaken).
Anyway, if you want the same height (or feel) as of CG125 then yes CG125 Deluxe is the only bike which will provide you that. I personally like Deluxe just because of [I]that[/i], because it gives you best control over your bike.
