Gear sprocket changes to improve acceleration - shdwghst457_imp - 06-26-2014
I would like my CB1100 to accelerate faster, allowing for some top end to be shaved off. I realize my cruising RPM will elevate with this, and because the bike is already really powerful I don't want to go to too extreme measures here. How can I make the bike pull harder? Should the front or rear sprocket be swapped, or both? Is one a more difficult endeavor than the other? Same question in regards to price.

Best way! Swap out the front sprocket to a 17 tooth and hang on tight ! Lol. Swapping the front down one tooth you can still use the stock chain length by just tighting the chain and the front sprocket is cheaper to buy! There is a website where they can make any sprocket you want. But I'm sure another oem honda front 17 tooth sprocket will fit your bike.
I would say you could pull the front tire off the ground by just gassing it with out having to dump the clutch. 1 tooth down on front on a street bike makes a huge difference. You will hit your 112mph speed limiter very fast in 4th gear and still have 5th gear ready for the ECM reflash

Are [url=http://www.jtsprockets.com/catalogue/model/599]JT Sprockets good?
There's a chart that says going from the 18 to the 17 in the front is hair more effective than going from a 39 to a 41 in the back. They have a 15 for the front!

Yes the JT are good!! No No No on the 15 lol. You could start off in 3rd gear
the 17 should be perfect

Ha! I don't want the 15. I'd be doing backflips like my RC car!

First gear would stand the cb straight up for sure! I did not see a price but the 17 you should be in good shape. It will pull hard thru all gears.

As has been said, you get more bang for the buck by changing the front sprocket - plus it's a much easier job.
Just one tooth down makes a fair bit of difference and you will feel it.
You already know that revs at highway speeds will be higher and you're ready to accept that along with a bit less gas mileage due to those higher revs.
But you're looking for more poop off the line so I don't think you care all that much about mileage
Have fun

Using my first grade math skills it looks like I'll be revving 5 to 6% higher at the same speed...I can live with that! The front is easier to change out? Didn't expect that.

You should be able to put all the slack in your chain move the rear tire all the way forward. Remove the sprocket cover and remove the front sprocket with chain then reinstall and adjust chain. It's not hard. You might and I would take the chain off the rear sprocket for lots of slack.

The internet is telling me that a smaller front sprocket will wear out the chain faster. Realistically, trying to hit 60 in 3 seconds is going to wear out the chain faster. For normal non-hooliganized riding, will the chain wear difference be significant? Would it be better to just put on a bigger rear?
Found the 17 tooth JT front sprocket for a 530 chain:
