yeah well, i think its kind of a hurry up and wait budget+balancing act w/buell to implement a perfect taller geared do-all streetfighter/touring overdrive 6th while still maintaining the nice original 5.. more power to 'em. they're probably saddled w/engineering+cost issues when HD(?) tactically eliminated the trapdoor trannie and (in my opinion) made it hard for the garage mechanic in all of us to service our own bikes including other 'harder to fix yerself' bearing type changes - suspect its a planned obsolesces thing; so, we can't keep em running forever by fixin em - i dunno, long-live the v-twin!

I read somewhere that the drive by sound requirements for a 6 speed bike are harder to pass. That would mean Buell would need to put on a more restrictive muffler and take some of the power away to get the sound level to an acceptable level.

Sounded fishy to me, but I wouldn't plan on a stock 6 speed in the XBs for a long time.

Shaggy,
Out of curiosity, why are you interested in a 6th gear. I have seen a few posts like this, It doesn't seem like much would be gained.

I remember a post about 6 months ago where someone wanted to lower the rpm's at hwy speed on a 9. He swapped gearing from a 12 onto a 9 (I don't recall if he changed the gears or the pulleys). Ultimately he was not happy with the change and did not recommend the modification.

I think buell was right on with the gearing on my xb9. It's a very good combination of, acceleration, mpg, top gear roll ons, and doesn't require that much shifting in the twisties.

The gearing that was changed was the primary gears and chain, not the final drive and belt.
As has been said before, making the gearing taller in that manner reduced acceleration rates.
If you want to be able to run at lower rpms on the freeway or have higher top end speed the easiest way,
currently, is to switch to chain final drive.
You can gear up for the freeway and change to shorter gears for acting like a hooligan.

If that 6 speed would give my buell a higher top end speed without changing my 1-5 speeds i would buy it without thinking twice... don't get me wrong, I love the torque in 5th but just once getting my bike up to 160+ and flying by some jap di#@head would make me a whole lot happier!!!

Kokko,
Like I said on a different thread, ideally, for top speed you should run out of hp just before you hit the rev limiter in your top gear. If you cannot pull the gears up to red-line you are not gaining anything. Having said that, I know that it is possible to build a 9 up to the point it puts out 100 or more rwhp while still being reliable and streetable. Having 30% more hp should allow taller gears than stock.
I would not try it on a nearly stock bike, the factory gearing is a trade-off between torque and speed. To increase one you will sacrifice the other.

Ejk: no offense guy, but gearing changes will not take your XB to 160 miles per hour. serious aerodynamic or HORSEPOWER gains will be required.
it would be CHEAPER to keep the Buell, and buy a 5 year old Busa for when you need a speed fix.

Well put Fullpower ,
I was thinking about picking up an old Busa and
retroing it to a sport touring bike ..that would be cool .
I will never change my XB12R to anything other than what it was designed for , to "me" that's what make's the XB'S the perfect real world sport bike ...

Here's another point about taking these bikes to the limit, speedwise. Your wheelbase is very short. As such, minor imperfections in the road surface become very pronounced at high speed. After I got my race kit I took my bike out to Ojai, CA. on SR33 northbound approaching SR166. It's long and straight for the last few miles before the roads meet. I wound the bike up as fast as I could get it to go and I ended up somewhere between 140-145. The reason I backed off the throttle was that the front end was skipping all over the place and I was pretty sure I was about to die.

These bikes are not meant for flat-out speed in a straight line. Fullpower has it right, get an old busa or some other race bike if you want to go that fast. Remember that when you lose a race to a jap bike you did so with class. All the other guy will ever have is his whiny little inline 4 to keep him company while he consoles himself to the fact that he paid Tojo for his ride.

You didn't get to 140-145. The limiter kicks in at 138. Mine has always been super stable at that speed.

XB's are known for their stability.

What do you mean by the front tire skipping? That sounds like something is wrong. Maybe and issue with suspension setup, steering head bearing, or tire pressure?

They wouldn't have to make a 6-speed tranny for a touring package.
Leave it as a 5-speed and make fifth a bit higher than 1:1.

M1Combat, my gauge regularly sees 145 mph. Then it kicks at the limiter, top of fifth. Probably right around 146. Maybe you should have yours reset or something if it's kicking in at 138..

138 is the actual top speed of the bike measured by GPS, but the gauge should read higher..

I agree with Tpoppa. If the front tire is skipping around at any speed, you have a problem that needs fixing.

When I went to european gearing on my ST-3 I could hit 160+ at the rev limiter on the dyno. On the salt it made 130 and some change. On the street my speedo was about 7MPH off and the RPM dropped to about 2K at 70 MPH. The chain kit cost just a fraction of the Baker 6 speed. But for an XB you will need to convert the swing arm. ... Terry

You can get from Trojan - their chain conversion. Uses the existing swingarm. I think Al Lighton had something he was looking into.

I'd seen the Trojan on Chaconas' XB12 racebike - looked good.

I've got the Hal's on mine and yeah... taint cheap.

Maybe I am missing the point but I thought you guys consiously bought an XB knowing its limitations. Perhaps the idea of having a bike meant for high speed work and an XB for skilled (twisty) riding is the best solution. I do believe Brother Erik got it right from day one and any fiddling should be restricted to a more expendable product( Crotch Rockets).
