Spoke wheels anyone?

Suzuki SV650 rear rims are that size, and they run a 160/60-17. A 160/70-17 should be fine on a 4.50 rim.

I'm curious about your 19" front rim. A 1.85 rim is very narrow - should only take a 90/90 - maybe a 100/90 width, but even then it would pinch it together and make the tire taller and less stable.

Back in the '70s, that was as wide as they had, so people put a 3.50 (about a 110/100 size) on their CB750s and CB500s, which made them handle much heavier.

Newer bikes run a lot wider rims. A Honda Rebel 250 runs a 1.85 rim with a 3.00 tire. A 335-pound Suzuki Savage 650 runs a 100/90 tire on a 2.15 rim. Triumph Bonnevilles run a 100/90 tire on a 2.50 rim. I would highly recommend a 2.50 rim so the tire contour is closer to the rear's.

Thank you so much for the info,extremely helpful. I’ve been doing some digging trying to determine what size will work,a 19-2-1.5 is what I’m looking at for the front and a 17-4.5 for the rear. I’d like to go with a 17-70-160 for the rear but keep getting conflicting info. Once again thank you,very helpful info.
