1981 gs850

Last summer I picked up a 1981 GS850 with a sidecar and I spent the winter getting the engine in proper working order.

So now I'm onto suspension, and I've learned about trail and it has struck me that if I were able to get my hands on a set of forks for a GS850L (which has leading forks) it'd reduce the trail a bit.

The 850L is only leading by a tiny bit, but then again maybe a tiny bit helps.

Is this sensible? I know nothing.

Wish I could help you about your change of forks. It sure sounds like a good idea. Keep in mind that change may change others areas (adjustments) on your rig.

But will tell you that your 81 GS850, was the best riding & trouble free scoot I ever own. Those seats carried me for 10,000s of very comfortable miles.

Best of luck to you w/ your neat rig.

That looks like a GS1100 16v (GSX1100) fork.

I know it is an 8V motor, I'm just saying that the fork looks like a standard 1100 fork with the axle before the fork. The GL versions had that too if I remember correctly.

And I actually had a set of gs850L forks in my garage (durr) but the upper tubes are quite pitted, and after disassembly one is missing a part inside so I still need to get those other forks. But at least I'll have lots of parts!

It may be worth your while to pull apart one of your original forks, as the lowers from the L may just fit with out buying the other forks. I used the tubes from a F7 Kaw, that were 3" longer on a RD Yamaha years ago for many thousand miles.

Turns out no. I took them apart and the upper fork tubes are about an inch and a half longer, and have a unique collar on the bottom.

I ended up buying the new forks; I had to swap out the brake calipers and the front fender to make this work.

I did a complete refresh, cleaned everything out and gave it new oil and now they're on the bike with air pressure. I'm just finishing up the paint on my new (to me) front fender and then I'll get that put on and I can test it.
