Thank you for taking the time to contact us. Yes, this is the recommended chain roller, according to our manufacturer. br>Boss Powersports, thank you.br>
Thank you for your interest in finding out more. br>We don't have quad fitments for these, but it's a strong possibility. With an 8mm bolt, the dimensions are 34mm x 24mm (diameter x width).br>Thank you, Boss Powersports.
Yes, with a small modification. This one has a nut on the bolt, whereas the stock frame mount has a nut welded on with a different thread, which I simply cut off with a thin cut. This is a better roller and less expensive than stock.
I'm not sure it will work with a lonher bolt because on my yz 125 2001an, I had to replace the top roller on the sub frame, not the big one on the frame by the drive sprocket!

The rubber roller had a smaller diameter. But it was the bearing assembly that I needed, and I was able to quickly swap it out for my worn-out rubber roller.
It's fantastic that I've gained 5 horsepower! Excellent work!!.
This is fine for the upper roller, which does not come into contact with the chain very often, but it is too soft for the lower roller. The lower roller had nearly disappeared after two rides.
It was a perfect fit for my 2000 Yamaha YZ125. It has a nice appearance and a smooth roll.
Frame modification is required, but it fits blasters and replaces bushings with bearing rollers.
Excellent item.
Very good product.
