I ordered one because to me the stock throttle felt like it has too much slop on the bar, actual slop between the bar & tube, not cable adjustment. Since some wanted to know:

Yes it will fit the 250S, the cable connections are the same. It is a tad longer though. It does have the "ring" near the cable side of the tube although with stock grips it looks like the grip will come to it, not over it like stock because like I said it is a tad longer.

I will not be installing it as it seems to have more slop than the factory one. Its no matter, it was only $9.99 & I can probably use it on my newly aquired XR350 project (anyone got a motor?).

 

Bummer about the fit, thanks for letting us know.

 

Is that ring supposed to be where the grip stops? i almost cut it off so the grip fit better...
