Primary roller bushings.

15mm gforce best so far and we've tried them all.

He is sure the 16mm are the best for our SW. But i have insisted a lot for the 15mm ... I was one of the first to torturate them for "R&D" 2 years ago .

15mm full width are the stronger one i have tested...

I have 15,5 mm now in my REAL yamaha clutch ....whit prototype bushing gforce has made out of torlon "xyz" tough as hell but to expensive to produce...

View attachment 160537 What are the best ones for longevity?

My stock plastic bushings were replaced with the Duralon after last season and only lasted under 1000 miles, so they are junk.
My 17 has around 8K on it, and I am putting the stock ones that I kept back in.

pic shows the stock bushing on left ready to go back in, and it is the only one that had any wear!

Are you still running modified stock weights or something different? I wonder if the aftermarket weights are harder on rollers?

Yes to modified stock weights.

Sounds like that brass bushing works best for longevity.

Who sells the brass bushings? What brand are they?

Thanks for the pic. I shall try the 15mm which is closer to stock height.

You can also buy just the bushing from them

As DCM stated, Gforce.
They come as a set of rollers with bushings, and come in two heights, 15mm and 16mm rollers.
They are also wider then stock, so they also come with skinny side washers!

Thanks for the info everyone!

Do not see that on their site, but maybe because I am viewing it with IPad and IPhone!

So, will those( just brass bushings) fit stock primary rollers, or made as replacement for Gforce rollers only!

Just ordered a set of 15 rollers. Dam good price!

Might have to call them. A few years ago i bought the bushings and a little tool made to press them in and out.
