Question about 47mm BBK Top Speed

[beeker]

I have a 2018 taotao atm50-a1 and Im looking to put a 47mm NCY bbk on it. I fully understand this will increase power and acceleration, but what needs to be done to the gear box to achieve higher speeds?

I think you´re fine with the stock gears with the 47mm BBK.

I also use it in mine, plus cams. Power is more, scoot also got a little faster, cause a stock 50 can´t open it´s variator fully on the slightest bit of uphill or wind or wheight...

Don´t expect too much of that 20 extra cc, it´s no 2 stroke tuning we talk about. It will accelerate faster and pull better. But won´t be a dragger after.

Cheers
