Cup Bike throttle question

[SPG]

From what I understand, the Cup bikes use an Rc8 throttle assembly. Can anyone with access to a Cup bike confirm whether they use both cables (open/close) or just one cable like the street bikes do.
Thank you.

Single cable. Comes throttle tube, and grips no cables. Hope stock cable works. I have one here awaiting arrival of right hand switch to be able to change them over.....

Does this fit? I am looking into the G2 or this Cup bike setup. What is needed?

Just put one in yesterday, the difference is very noticeable, much better control and response. You will need to grind down the stop a little so that it is not over revving at idle but highly recommended mod!
