GS1000 tire size

Could someone tell me what the front tire size is supposed to be for a 78 GS1000E?

Thank you!
 
The bike came with a 3.50V-19 on the front. The wheel is 1.85" wide. It's almost universal here on GSR to run a 100/90-19 on the front, the width will be basically same as stock.

For the rear you should have a 2.50 x 17" rear wheel which can take a 120 or 130 width tire - most GSR'ers run the 130.

Hope this helps and good luck.:)
 
Thank you for the information! My speedometer seems to be off by 10-15 MPH I thought maybe I had the wrong size tire on the front but that is not the problem . I guess I will just have to get used to it.
I appreciate the info!

Our 78 1000 is also about 10 mph optomistic, must be a bad batch of bikes. ;)

I would guess it probably has something to do with the JAPS and the metric system.:-# LOL

All joking aside, the speedometer works off magnetism; a rotating steel dome inside the speedometer spins as the cables turns and the needle gets pulled along by a magnetic pickup. The needle itself works against a spring so depending on the spring force, the speedo can read high or low (which is most common). Frankly, I'm amazed the crazy things are as accurate as they are.
 
Before we put new tires on my wife's bike several years ago, it had a 90/90-19 (I think that was the stock size) and the speedo was off by several MPH. I installed a 100/90-19 to slow down the speedo and now it's near perfect. At an indicated 70, the GPS shows about 69.2. Odometer accuracy is about as close, too. The last trip we were on, the odometer showed about 1400 miles, the GPS showed about 1420.

Both of those errors are VERY tolerable in my book. :D

The odometer is direct geared so it should be accurate. The speedo on the other hand...:mad:
