ordered 1 tooth up on the rear for my 01 R1.Spoke with a friend who had a 98 model and he went up 1 and said it slowed him down so he went back to stock(racing straight line from a second gear roll)is the gearing the same on the 00-01 compared to the 98-99.any of you guys 1 up and did it scrub off any top end. if it allows you to pull a few more revs the speed may stay the same but dont want to revving allot and not goin anywhere(like when i tried going 2 up on a 95 zx7 went through the gears fast but was slower than stock gearing) sorry so long.

I have tried 3 different gear ratios in the back.. 1,2, and 3 up.. neither 1 or 2 affected top end, and the 3 only affected maybe 2 mph on the top.. The 99 with 3 up is an animal, even when I lower it for drag racing,power wheelies in 1st and 2nd are effortless. I personaly like a 45 rear, 2 up as my favorite

I went 3 up in the rear on my 2000 R1. I just love it. I think the top end looses more like 5-6 mph. But I still think 165 is still plenty fast. /images/icons/smile.gif

3 tooth up will help your 60 ft times but after 70mph a stock geared bike will walk away from ya trust me you may be going through the gears much faster but ya not covering as much ground. i am looking to pull 5th and 6th just a little quicker.I would run 3 up for 1/4 mile drag racing we run from a second gear roll on deserted interstates so 1 tooth might help or might hurt me i guess i will find out when i get it.

I agree. But, it's much cheaper to change the front than the rear. -1 tooth up front is vitually the same as going +3 on the rear. The gear ratio on -1 up front would be 2.87:1 and the ratio with +3 in the rear is 2.88:1. I would just change the front if you're going to do +3. It will screw the speedo up pretty much the same either way unless you get a yellow box.




If you want to know how good the tail section of an R1 looks...Just ask a Honda rider!/images/icons/cool.gif

i read somewhere that going up in the rear will better your handling rather then going down in the front. the article said that it had something to do with shortening the wheelbase. anyone know.

That is right.
Going up in the rear pulls the rear wheel closer to the front. Making the bike turn faster. Going down one in the front makes the wheel base longer there by making it turn slower. Not really all that noticable though.

As someone stated,it really throws the speedo off.. I have heard of this " yellow box " where are they available from ? I seem to allways be goofing with the gearing for drag racing, or out playing..would like to try and make it a little more accurate..... Thanks !

I have a yellow box and it works great. I went up 3 in the rear and it really threw the speedo off by 20 percent or so. Now I am right on the money.

for the people who have the yellow box, did you install it yourself or did you have someone else/shop do it?

did any of you have a problem going up two teeth in the back and the chain being too short? I was thinking about doing it but I have a new DID Xring chain and had it cut to the stock length. I don't want to order another new chain just for the sprocket....

Yes my motorcycle is fast..
No you can't ride it!

I went down 1 in front, and I'm about to go 3 up in back. I don't spend much time at top speed, but a lot of time sprinting around town, or in the twisties. I rode my friend's R1 with that gearing, and wow! If you can keep the front end down, it hauls ass!

Make sure your brain is bigger than your balls!!

Azsportbiker and Winko... if I can do it anyone can! /images/icons/laugh.gif I installed it myself in about an hour. If I knew what I was looking for... I would have saved myself some time. I say it can be installed in less the 30 minutes. Instructions are good from black robotics. If you actually buy one... I can take some pics to help you out with the install.

JonnyBlayz... I bought a new 520 chain setup and I DID NOT cut the chain until I had everything on the bike. I was 2-3 links longer the stock.
I went up 3 in the back.
