I thought this was Buells bike for aggressive riders! There is no room in the turning radius for broadslides! It seems to me that this would be a must for fun dirt riding or riding it like a supermoto. Somebody needs to make a more forward triple tree maybe with a rear front axle mount to keep the rake the same. If any of you Buell factory guys read this I believe this would make this bike nearly perfect!
I do like your new setback front chin fairing so you don't scrape with your front wheel when doing stoppies.

I would be happy with just adding a stock wheelie bar so I don't have to keep buying new tail lights.

Well...I must have a completely different bike than you guys. I don't have a problem with the turning radius. I can carve the tightest of twisties and never have an issue. My other bike is a Ducati, so perhaps I've just grown used to three point turns in parking lots.

And wheelies.....well....I've tried grabbing a handful, and managed to float the front wheel a few inches, but no stand ups. Nothing at all like my Monster 900 which will damn near loop your a$$ if you aren't careful in first gear and over rises in the road.

I think no one has ever had an issue with turning radius except when trying to do tight u turns, leastwise not that I can remember reading...

I had thought about the triple trees also and agree that this would be a way to get more degrees of steering lock. This would also increase the wheel base and hinder wheelies to some degree (negative). These triple trees would probably be a very high priced item. I'd rather they just indent the frame/gas tank on future models to allow the increased steering lock. They could add to the gas tank volume right behind the indented area on each side. Give us a quart more per side or at least the amount the indent removed.

The turning radius was mentioned as a problem in Dec Rider and Nov Motorcycle Consumer News just to name a couple.
I would like to see them make a more forward triple tree with a rear mount axle to try and keep the same rake. This way we could upgrade our bikes with a kit instead of buying a new bike or changing our frames.
Don't get me wrong I love my Uly but I just wish it was more Supermoto friendly.

Chad, if you can't get your bike's front wheel up with your big a$$ on it then you need some motor mods! LOL On hard acceleration when I hit about 4500RPM mine starts looking for UFOs. Now don't get me wrong, I'm no lite weight. At 6'2" and 280 I've got a good chunk up top but at your height I wouldn't think youl'd be able to get full throttle in first without a wheelie.

Yeah, Chad. I damn near ground-looped mine. Tore off my tail light ($53 and change from Daves). And I'm just a normal-sized small town caucasian guy.

Roll it up to 4000 rpm in first gear and whack the throttle the rest of the way open and up she comes... Not as intimidating as my ZX10R since you're only moving at about half the speed when it lofts, generally just allot of fun and really predictable. Back off for a split second and make a quick clutchless shift into second and it'll ride back down smoothly.

Maybe based on size or weight, it's help to slide a little further back on the seat... If yours doesn'y wheelie it'll be the first XB anything I've heard of that doesn't! Maybe you ought to run it on a dyno just to make sure it's healthy? Just a thought.

Oh yeah, back to the point... More steering lock would be waaaaaaaaaay beneficial in the dirt where sliding could be allot faster and more aggressive. I think triple clamps would be a great idea if it allowed the whole front end to push forward an inch or so. Personally though, I would not want the axle moved rearward as it would make the angle very steep. Then again, if they offered a set-up such as this from the factory they could also take away the sales to BMW guys that feel they need a larger diameter front wheel for their work in the dirt. And FWIW that appears to be the only area the Uly doesn't rule the Bimmer in now!

Again, just a thought...

I just read a Paris to Dakar article and they only run about 12 to 18 psi in their tires. Maybe the high tire pressures are making soft dirt riding more difficult.

I believe the low pressure is simply to provide added flotation, but those same bike are generally running larger diameter fronts as it helps minimize the angle of deflection when you are running across uneven terrain.

I have no problem with the smaller front diameter based on the fact that I ride dirt roads on the Uly and not "off road". With that said, relatively smooth dirt roads are normally great playgrounds for controllable (usually throttle induced for me) slides and unfortunately more steering movement from side to side is something my Uly doesn't yet offer.

I think the triple clamp idea is a great one as it was originally asked...

Again, just my thoughts on it.

Dirtbikes in general run low pressures in their tires.I run about 18 psi in my KTM,any more and the front starts to go away in turns.

If you wanted to run very low pressure in your tires on the Uly, wouldn't you need to switch over to a tube-type tire? With a tubeless tire and very low pressure, wouldn't you run a risk of deflation due to unseating of the bead when running over really harsh terrain?

This might not be the case at all, but thought it would be prudent to ask.

Guess I expected the Uly to point skyward from about 2500rpm or so since it has all that abundant torque down low. My Ducati will easily wheelie right off idle, even with my 225lb butt on it.

I did finally get the Uly to come up, but I had to roll on hard about 5000rpm to do it. It came up quickly and the belt drive makes it easy to control.

I'm not a stunter wheelie junkie, but I do like to lift the front wheel up from time to time, just for kicks. Don't do it much since I'm concerned about trashing fork seals and the like.

If you run low pressure in your inner tubes on a dirt bike you need to have rim locks. Otherwise you can rip the stem off your tube, get a pinch flat, etc.

I don't know how low (PSI) you can go with a Buell tire before slippage is an issue but I would guess you should be able to go down to 25 psi without the beads letting go.

Anyone know?

Regards,

Jim in Santa Barbara

I'm comfortable with the bead holding at 25lbs, but I don't think is much to gain by going low on the Uly. I'n not thinking anyone in their right mind is going to take on serious sand on one, and honestly we can;t really make comparisons to strategies used on "true" dirtbikes.

If you want to let a little out to get a little softer feel that's probably fine, but it's not going to make a big difference and we have enough suspension to let that do the work instead. Given the fire roads and stuff I plan to ride most, I'll leave the pressure right on the money and will enjoy the twisty pavement getting to and from those mountainous dirt roads.

Oh yeah, I'd still buy triple clamps that would allow for tighter turning...

I'm not sure lower air pressure will change much on dirt roads without having knobbies. I've heard that the lower air pressure lets the knobbies pinch or grab at the dirt.

I know going from 30 to 23 psi on my F650GS (with knobbies) made a huge difference on forest service roads.
