83 GS1100E chain and sprockets upgrade??
- Thread starter P09luis
- Start date
15T + 3T = 18T front (you need this size in order to match the original sprocket diameter)
2.8 x 18 = 50T rear sprocket. If you want lower RPM then you can go to a lower tooth count.
1100E uses 96 links in 630. 96 x .75" (link length) = 72" long chain. A 530 chain has 5/8" between links. 72" x 8/5 = 115.2 (use a 116 link chain in 530)
1100ES uses 98 links in 630

The 530 - 17 tooth sprocket is the same diameter as the 630 - 15 tooth sprocket
This is incorrect.
Pitch diameter for 630 15T sprocket is 92mm
Pitch diameter for 530 17T sprocket is 86mm
Pitch diameter for 530 18T sprocket is 91mm
I've seen both recommended but I went with 18t.
I've a bit more hp/torque with a '84 1150efe plus additional boost from headers and rs36 flatslides. 18t front, 45t rear to lower rpm.
depends on what you're goals are. I've come across quite a few people running 17 and 16 without issues.
A 47T or 46T rear sprocket will help out with this situation, it will also give you less rpm on the highway.
No. 18T front and 46 or 47T rear. All in 530.
What's efficient for one rider isn't for another rider's requirements. Subtle tuning differences are possible with various combinations, not that important to me but for others it is.
One tooth on the front is equivalent of 3 on the back.
What Nessism said:encouragement:
I had the same issue. For myself going with 18/45 resulted in more useful gearing in the city and on cruising on the highway.
Lighter chain and sprockets matter they have an effect handling as things that spin don't like to turn.
Depending on the sprockets there will be a weight saving, in my situation it was 3lbs, 3lbs less spinning at high rpm. You may not notice but small details matter.
