Whats the likelyhood that my bike CAME with a 26t front sprocket(pully, cog whatever)?

Last night, found out my top speed is around 130..revlimiter limited....

On the up side, I was walking all over everthing else till right around 120, when my buddies 748 caught up and passed...then the rest passed me...

I ask becuase, first I know, no speedo is worth the crap after about 90-100(except, in a cop car),
And, my buddy's XB9, passed me at that point as well.....

Not angry, or even embarassed...I have more USABLE power...but...just wanna know....

Your bike comes stock with a 27 tooth front sprocket not a 26. Harley/Buell does not even make a 26 tooth. It is an aftermarket only sprocket. 130 top speed is about right for an X1.

Chase,
I've been clocking my speedo with a GPS at triple digit speeds, it looks like the speedo is pretty damn accurate, at least within 5 mph.

Of course the GPS could be way off I have no way of testing that.

I've been able to test to abut 123.4 or so

The rev limter on a tube frame domestic bike with 27 tooth front pulley should kick in at around 140 mph give or take a fair percentage due to effects of varying tire sizing/wear.

I think 130 might be a little slow for a '99 X-1 but it's in right the neighborhood.

I saw 135 on the speedo on my Y2K-M2 once while I was going down hill with a tailwind. I thought there might have been a few MPH's left but not many. Then again, maybe your speedometer is just more accurate than mine.

BTW: According to a Buell Pulley Gearing [Excel] Spreadsheet (that I would be happy to e-mail to anybody that wants it), the actual top speed of a tuber Buell at 6,800 rpm with U.S. gearing (27 X 61) is 138.8 mph. Full Euro gearing (29 X 55) equals 165.3 mph @ 6,800 rpm in 5th gear.

Sixth gear in a Baker six speed unit is a 0.85:1 ratio final drive ratio, as compaired to the 1:1 Buell fifth gear. You can do the math for top speed and RPM's at, say, 70 mph.

You are absolutely correct Blake! 142 to be exact, remind me to tell you about it someday.
That is a little slow for an X1.
