Performance bias tires for '80 GS750

[long_av8r]

I tired the Dunlops and wasn't a big fan. I switched to Demons and I love them - this is on my CB900F though, which I imagine has similar handling characteristics to the GS's.

While it's clearly a different bike, the 250prod guys who run stock wheels tend to go with the GT501s. They say they're very similar to the sport demons, and that the largest part of why they use them is dunlop has good support at the track.

I have these on my 1980 750e and a friend has his on his 1980 CB750f. We both love them. I did a track day with them and they handle great. The turn in characteristics are fabulous and they stick like glue. I also have about 3500 street miles and they still have some life in them. I am using the 100/90 front and the 120/90 rear. I highly suggest you check out these tires.

:-k Hmmmm... "...stick like glue", I like it. What tire pressures are you running at the track? By the way, you have a pic of your '80 750E? That's the year I have.

I was running 32 front and 34 rear. these tires are the best that I have tried yet. Way better in my opinoin than Metzlers or Pirellis. I will have to take a pic of my bike and post it up. I am currently in the process of installing a 1983 1100 swingarm. I love this bike.

Does the 80 vs. 90 aspect ratios make much of a difference on either front or rear?

This is not a direct answer, but I think what you're getting at is, "can I use a wider tire if I lower the aspect ratio". Is that right?
I was running a 130/80/18 rear. (po installed, not my idea) I went to a 120/90/18, and it handles quite a bit better. In the corners, the 130/80 always felt like it was squared off even though it wasn't. It was "pinched".There was simply too much tire hanging off both sides of the narrow 2.15" rim.
You could go to a stock 17" rear rim. The were 2.50", but I like the way my bike handles with the little 18".
On our old bikes, I think there is more lost than gained by running wider tires.
