Gearing question.............................

I want to lower the RPMs on my Gixxer a little on the freeway since I do a lot of freeway riding. I'm going the cheap-azz route of front sprocket for now. I'm running (I believe) a 45 tooth on the rear and I know I have a 15 tooth on the front. How many teeth would you guys suggest going to? I know that 6,500 RPM isn't TOO terribly bad, but it's a more comfortable ride at around 5,500 to 6,000.

Thanks for any help!

1 in front is supposed to be = to 3 in the rear. +1 in the front would prolly be about 5-600 rpm difference. The engine will work harder to maintain those rpms i.e more throttle . You have to find the balance. Start with +1 and see what you get.

Thanks for the reply. Normally it's not a big deal, but I'm going on the Galveston ride on March 6th and I need a little relief if I'm going to be on it all day. The front sprocket is cheap and easy to change. That's why I'm going that way.

Jeebs, you are complaining about 6.5k rpm's while I chug along at 10k rpm doing 70 :(

Although I must admit, When Im on the back roads riding to school and chug at 6k on 6th gear it's pretty peaceful

Check http://www.gearingcommander.com/

This is a site that will get you the answers you need. You can play with tire sizes as well as front and rear sprocket sizes for a whole host of bikes, and determine the impact of the gearing change on rpm and speed by gear.

If you are going to go ahead and change you gearing I would change the rear sprocket. I say this because it is something that is easier to do than change the front if you wanted to have weekend gearing for example.

Well, I put the new front sprocket on today (thanks Mainland Cycle Center) and took it out for a ride. There is no noticeable loss of power at all. At 70 MPH, I went from 6300 RPM down to 5800 RPM. That is a comfortable level. I use to get a decent little buzz through the bars at 70 that would put my hands to sleep ( Carpal Tunnel Syndrome), now that's gone. After looking at the old sprocket, it was pretty much time to change it out anyway. To all of the people with CONSTRUCTIVE responses, thanks a ton....... To the wise , GET BENT...............

Weighted bar ends may help too.
