Is it possible to change the rear sprocket on the XT to one with fewer teeth to give more low range pull? I'm thinking of a quick fix untill I get a new set of bigger headers. | ||

Changing to XB9 primary gearing is the easiest way. You change the front sprocket/rotor and chain for about an 11% difference in ratio. | ||

You got it mixed, it would be a bigger rear sprocket or a smaller front pulley, this is not possible un less is a chain driven bike. So the option is the XB9 primary gearing. | ||

Actually, Baker Drive Train has a 26th sprocket that will fit the Buell line. However, you would have to find a way to modify the belt tensioner to keep it under constant tension. Good Luck | ||

The xb9 kit is the easiest way to get what you are after. Have had mine in for 15k and would not have it any other way. It is a fairly easy install, as well. | ||

Is this what I'm after? http://www.ebay.com/itm/HARLEY-DAVIDSON-34T-34-TOO TH-FRONT-PRIMARY-ENGINE-SPROCKET-BUELL-XB9-FIREBOL T-/261067400193?pt=Motorcycles_Parts_Accessories&h ash=item3cc8d46401&vxp=mtr#ht_158wt_932 | ||

That sprocket looks to be for an 08 or newer models if your bike is an 07 it will not work. | ||

According to his profile, his bike is an 08. You need the sprocket, a different primary chain, a new crankshaft bolt, and a primary cover gasket. American Sport Bike sells everything you need in a kit: http://www.americansportbike.com/shoponline/ccp0-p rodshow/A17192.html | ||

The eBay sprocket is for a 2007 and prior. The 2008 and up comes with the rotor and sprocket together. | ||

Cheers for that Hughlysses, can anyone who has this installed tell me the difference in top speed? | ||
| Pontlee77 |
well i guess if gear reduction is 11% i suppose top speed decreases acordingly, i seem to remember some one saying that you would be working 300 revs above of the XB12 stock primary. | ||
| Hughlysses |
It might not actually decrease your top speed at all; it depends on whether the bike was capable of hitting redline in 5th gear with the stock primary ratio or not. Often a motorcycle will achieve the same or even a slightly higher top speed in 4th gear because the engine can achieve maximum RPM in that gear. If you can find a detailed road test on the Uly showing the top speed in each gear, it'll answer this question. | ||

I absolutely love a belt drive but I've always fealt that the fixed tension belt pulley is a design flaw. It should have been either adjustable, with lock nuts, or used a very heavy spring tensioning. That would allow for nearly whatever belt drive ratio the end user wants and also make belt changes much easier. | ||

I have an XB9 gearing kit from American Sportbike that I bought and never installed. I'm never going to install it so it's just collecting dust. I opened the box to look at it but other than that, it's as new and never used. If anyone is interested, let me know. Tipsy | ||

Tipsy: May we inquire as to what years it would fit? Thanks | ||
| Tipsymcstagger |
My bike is a 2008 XB12X. I would imagine a quick look at the American Sportbike website would clear up any questions concerning compatible models. Tipsy | ||

I swapped my '06 Uly gearing for XB9 a few years ago and really like it for my mountain riding. It's OK for highway as long as you are not planning on running 80mph+ all day. Can't say about top speed, as I have never attempted a top speed run before or after. I would think it only matters for track use of speed demons, which I would think is not really the Uly forte. Anyhow, I suspect it would not drop top speed by much at all, since it seems that the Uly would be top speed limited by air drag at our horsepower levels. I could be wrong though - just my theory that I do not plan to test. |
