Radials vs Bias Belt Tires

Post by Solina Dave » Wed Oct 23, 2019 1:27 pm



I've got a '78 GL1000. Ever since I bought it back it the fall of '77, I've always used bias belt tires. I see radial tires available, that are the same size, with reviews claiming pretty good mileage, but I'm curious about potential handling differences.
Radials for motorcycles apparently appeared in 1983. Does anyone with a motorcycle made prior to 1983, have any experience with the use of radial ply tires? Did you notice any changes in performance, either pro or con, and what's your general opinion of them?

Thanks........Dave

Hey Dave
Did you find your answer? I see you asked this in October.

There are write ups on this.
You have to take into consideration that when the radials came into play they were put on sport/racing bikes with single rear shocks, not the dual shocked bikes. Yes, you will get a looser feeling in the suspension/frame flex will happen from the better grip of the tires on the road surface.
Can you put them on? Yes. Just be aware there will be a change in the bike feel and handling.
If you haven't done a web search, try changes in handling of radial tires vs bias on older motorcycle

Thanks for your reply. That's interesting about the looser feel in the frame and suspension, with the increased tire grip. I will search for comments, and comparison testing.
I've been using bias belt tires for over 40 years without a problem, and I'm a very conservative rider. So maybe it's a case of, "if it ain't broke, don't fix it!" :lol:
