Hmar02 Posted April 21, 2022 Posted April 21, 2022 Good evening everyone. I just found this site when I was searching a question, and I hate to ask right off the bat but I need help. About a month and a half ago I picked up an ‘81 GS850 GL that had previously been used for parts. Now I’ve got an ‘82 parts bike and GSX-R forks i picked up to avoid the need to rebuild front forks and calipers, not to mention the added looks and added handling benefits. This is my first build but I wouldn’t say that I’m in over my head, just short on time and money so things are moving along slowly as parts arrive. Right now my biggest focus is getting a title so I’ve put a hold on things until then, but thats all beside the point. Now that I’ve given a brief introduction of my bike and myself, I have a question. Someone on a Facebook group recently mentioned to me that a VX800 rear wheel will bolt right up to a GS850. Is this true? If so which caliper should I use? I thought the 5 point design would look cool with the 3 point look of the GSX-R wheel up front. Then both wheels would be 17” but im not sure if that would cause any issues. Lastly, what would be a good tire size and psi to run front and rear witb the wheels mentioned? Sorry if this is a stupid question, if you’ve read this far thank you and I look forward to learning in this group. 1 Quote
wraith Posted April 21, 2022 Posted April 21, 2022 So, the answer to will a vx800 rear wheel fit the gs850, is yes. The main pain with this, is you need to remove the hub to put the wheel in/out as the tyre is a bit fat to go past the inner hub. (I had a 160 on it but you can fit the 150) us the xv800 caliper hanger and disc, you can then use a vx800/gs500/gsx600f/gsx750f rear caliper. Tyre pressure is down to the rider, I ran 38psi in the rear. Front try 36psi. And welcome to OSS 2 Quote

Hmar02 Posted April 22, 2022 Author Posted April 22, 2022 Alternatively, has anyone used the stock wheel for their bike on a fork swap with the newer brakes, but maintaining the old school speedo gear? Quote
