Wider Rear Tire 1978 GS750

[Scudder]

This topic has already been covered, but I'd like a few opinions. I know size of tires recommended for my 750 Front 3.25/90/19 and Rear 4.00/90/18. But... I would like to put a wider rear tire on. How wide can I go on the rim of a 1978 GS750? Or better yet, how wide have some of you used on your bike?

Thanks,

Scudder

Search function Scudder. This topic has been covered again and again.

Bottom line, a 120 is the max recommended tire for your rim which is 2.15" wide.

Covered too many times, but if you put anything wider than the reccomended tire widths on motorcycle rims you will get a distortion of the tires contour and the handling will suffer. I know this from experience.

Oops

Ok. I searched it. Should've done that first. Thanks anyway.

Why would you want a wider tire? I have no trouble with grip on the road with stock size tires. Plus they are cheap.

Switch to a 78 1000 wheel, I believe it's only a bearing swap & then you can use a 130 tyre. Check clearance for swingarm, brake torque arm etc.

No probs running a 130 (120 stock) here on the '81. Just a mosquito's ass hair off the brake stay.
