I went off the bar from my F3s and compared that to the one off my RT, and they are the same. I am surprised the F3L is less thick!
There is some confusion about the different sway bar options. And frankly, some bad information as well. I think this is always the case with any product.
These are round numbers but close enough for the discussion.
The stock F3 bar is 9/16" diameter. The stock RT bar is 5/8" diameter.
The F3 BajaRon Bar is 5/8" diameter (essentially the same as the OEM RT bar) and this is what gives the impression that the OEM RT bar will function the same as the F3 BajaRon bar.
The RT Bajaron Bar is 11/16" diameter. I won't go into the other important sway bar parameters as I've already covered this in a previous post. With a bar this small a very small amount of difference can make a great deal of functional difference in the way a Spyder handles.
I am surprised to being the RT and F3L are only about a 25 pound difference. But mine corners a little better. But not a lot. That is why I'm asking about the Ron bar. I had the Ron bar on my 15 RTS but it was thicker the the stock RT bar. It was a night and day difference in handling.
Those who have gone from the OEM RT bar (installed on an F3, etc.) to the BajaRon bar have noticed significant improvement. Of course, not as much as going from the OEM F3 bar to the BajaRon bar. There is a money back guarantee on all BajaRon sway bar kits if you are not satisfied with the improvement it gives you.
I had a Ron sway bar on my RT and Ron told me himself that the RT bar would not fit on my F3..... hmmm
This may have been a misunderstanding. I have never told anyone that the OEM RT bar will not fit the F3, as obviously it will.
What I do tell customers is that you should never install a BajaRon RT Bar Kit on anything but an RT (though it will physically fit other Spyder models). This is because too much sway bar can be dangerous. A too stiff sway bar will handle amazingly well under good traction conditions. But as soon as traction conditions are less than ideal, you may get out of shape and lose control with a too stiff sway bar. For example, wet roads, sand, etc. Though you will lose some handling improvement under ideal conditions with the correct stiffness sway bar, it will not give you this negative downside in poor traction road conditions.
Race cars have tune-able sway bars which can be perfectly matched to tire traction and current track conditions. But a street sway bar needs to work well in any and all possible conditions. This is why it is important to install the correct bar kit on your particular model Spyder. The right sway bar correctly installed will not only make your Spyder more fun to ride. But it will also make it a safer ride. And that is what we all want.
If anyone has any questions about the BajaRon bar kits or anything else I carry, I am always happy to give you as much information as I can. Customers who know the facts are much more likely to get what they want the first time. And much more likely to be satisfied with the results.
I hope this helps.
