TGB rs 50 or r50x Gear up kit

[trigen]

Hi there

Need some help on finding a good gear up kit for my Tgb bullet rs 50, its essentially the r50x

Anyone know which ratio (teeth) is standard on it?  What brands would fit? anyone that could give me some good options.

Currently i am running stock with restrictions removed and performance exhaust.

will upgrade crankshaft and 70cc later, not going to mess around much with any variator upgrade as its a marginal increase in topspeed

Looking to get around 80kmh (50mph+) or more on it

Looking at the parts manual (2009 but i have a 2010 scooter) it looks to be a 15/35 primary and 10/51 secondary giving a ratio of 11.9

Would it be correct to assume thats the gearing in my 2010 bullet rs 50?

Im also having a hard time finding a gear up kit that would give me about a 10 ratio, Would most likely have to change both prim and sec Changing prim to 15/40 decrease top speed by about 14% ? and polini secondary 14/40 would give way to tall gears at 6.6R 44ish increase

Any tips on a combo that would work well?
