GS750G Tyre Pressures

[ian1402]

Hi, does anyone know what tyre pressures should be used on a 1981 GS750G Jap import shaft drive, the tyres are Shinko a make I've never heard of?

[Billy Ricks]

Measure your tire temperatures cold and then again hot. You want to see about a 10% rise in pressure when you have it right. Less than that and your tires are staying too cold, more than that and they are getting too hot. Neither is a good condition. A good place to start might be 30 up front and 35 in the rear and see what happens. Alot depends on how much weight the bike is carrying.

Ok that's should better than the 25 front 28 rear currently in them, thanks.

First of all,

Second of all, I agree on the 10% pressure rise theory. To see if you are getting your 10% rise, you need to ride the bike to warm the tires well. A spirited, 50-mile ride will do nicely.

Third, I also agree about the 30-35 psi starting range, but also look at the sidewall to make sure you will not be exceeding the maximum pressure for the tires.

Plus, it's an excuse to ride more!

And take some pictures while you're at it. I've heard of the mythical 750G, but I've never seen one.

Hi Mr. ian1402,

A GS750G! Cool! Whereabouts do you call home? I doubt I will ever see a GS750G in Southern California.

I'm not a small person and I ride an 850. I run 32-34psi in front and 36-38psi in back, depending on conditions but also loosely adhering to the 10% rule.

Please click here for your mega-welcome, chock full of tips, suggestions, links to vendors, and other information. Then feel free to visit my little BikeCliff website where I've been collecting the wisdom of this generous community. Don't forget, we like pictures! Not you, your bike!

Shinko tires? Not very popular. From what I've read on this forum they are OK. I think Mr. Larry D put on a set a few months ago. I wonder how he likes them.


Thank you for your indulgence,

I was running 28-36. Just upped to 36-42 as per Avon's web recommendations & noticed some positive handling improvement. Not a lot but a bit.

Welcome to the site Mr ian1402...very informative site with nice, knowledgeable people, you can learn a lot ! I am assuming the 750G must be a rare bike here in the US?

By the way he spells "tyres", I suspect Mr. ian1402 is across the pond. I always thought the GS750G was a Japanese-only model.

I'm reading Reg Pridmores's book and he mentions tht most manufactureres say the pressure should be much higher than actually needed to prolong longevity. Most are saying 40 psi + but he advizes 32 to 34 psi or even 30 psi or less.

I have run at 40 psi as per manufacturer's suggested but now have turned down to 32. I'll see how it works.

Over pressure may give longevity but who knows for sure.

I'll run this way this season and see how i do.

Cheers,
Spyug.

Good point on the "tyres" Mr BassCliff....something I overlooked....

I see now that it was only available in Japan. I had been to that very informative link many times looking at different models, but had not noticed the 750G. Thank you sir!!
