Hi Guys, the 750 I bought has a too big rear tire on it. I usually go with BT45s on my 70s bikes, the profile seems to work well on them. So the 750 has a 130/80-18 on the back. I see there is both a 120/80 and a 120/90 available in the Bridgestone. My GT750 took the 90 but I don’t know about the Kawasaki.
What works best and looks right?

Thanks
Mark

Might depend on rim size....are they stock?

Yes, stock rims.

Thanks

I don't know stock triple stuff at all but theres always the resource site:

Yep, that's a valuable resource for sure. It looks like the /80 is just under the 4.00, and the /90 is over the 4.00. I was hoping for someone's real world experience who has a recommendation as far as road feel and handling.
By the way, I read your orange bike build, really nice!

I have 120/80 on my H2C. The bike has slow steering, I suggest the 120/90 as long as you're not already on tip toes at a stop light.

Thanks for that Mike. That's what I'm looking for.

In my case the rear rim is a 3" Lester. I've had a 130/80 and a 130/90 Bridgestone S11 on it and I can't tell any difference in handling at all. Mike, I'd look for something at the front end to quicken up the steering.

Jim, I dropped the fork tubes about half an inch to quicken steering but I'm being careful to make sure the front fender won't bang into the center chamber. Also running taller shocks, about 13.5 inches.

I ran a 130/70 on my 74 H2 and use the same size Avon Roadrider on my H1. Both have stock rims.
