I asked this on a few other boards, but if someone's going to know the answer its got to be here. anyone have experience with the Uly (buell xb12x) and and knobbies? I'm trying to go to this offroad school, but no knobbies, no entry.  , and I'm too broke to buy another bike at this point. tx in advanced brane | ||

I read on sport twin the interview with erik buell and some one asked this and he basically said no it wouldn't work because it would not handle well on street.... also it's a big bike for really taking on small small trails. I'm sure it could be done though it would just be a case of finding a knobbie tire that fits the rim | ||

As a point of reference for you, I put some Dunlop DOT (approved for the street) knobbies on my DRZ400S. They were great in the dirt but marginal on the street. Hard cornering on the street had me with my foot out motocross or flat track style in anticipation of low siding and at elevated highway speeds (70 or so) the front end tended to wander. I'm not saying a Uly would be the same but I'd suggest caution if you plan to switch. | ||

With the existing close clearance between front tire tread and chin fairing, it may be problematic to get a knobby tire to fit the Uly front wheel. But maybe a little custome surgery on the chin fairing might open up some possible knobby fitment applications. Maybe a Bridgestone TW42R BW TT in 120/90-17 or a TW22R BW TT in 130/80-17? Maybe a Metzeler Enduro 3 or Karoo II in 130/80-17? Find information on the Metzeler tires at http://www.us.metzelermoto.com/media/m_full_line.pdf For the rear, maybe a a TW152R BW TL in 150/70R17M/C or a Metzeler Karoo in 150/70-R17? None of the above are anywhere near perfect fits for the Uly, but they might work, or they might be horrible and dangerous. Someone, somewhere is going to fit up a set of knobbies to a Uly. I'd be very interested to know if there are some knobbies out there that can be adapted to the Uly. | ||

I think you just saved my ••• with that bit about the front fairing. this definitely warrants some more indepth thought before just slapping some tires on and hitting the trails. thanks. | ||

Even with stock tires on the bike, I've seen a lot of XBs, including a Uly or two, where the front tire smacked the chin fairing coming down from a wheelie. There's definitely going to be a problem if you go with a knobby. | ||
| Blake |
Seems more likely the front tire would approach the chin fairing during very hard braking due to fork flexure. I cannot see how coming down from a wheelie would cause the same type of deflection. | ||
| Prior |
Blake, I could be wrong. Dave and I had a bit of a conversation, for a man that doesn't wheelie, some of the bikes he's ridden have some really big rub marks on the chin fairing. I guess I see a hard impact coming down would cause a large deflection in the forks as well, but I'll digress. We're both engineers and we all have our own thoughts... Might have to figure out a model to prove either theory... | ||

I don't think doing wheelies makes the marks on the chin fairing. If you look at the angle of the forks when they hit the ground they would deflect away from the chin fairing not in to it. I would say there is more likelyhood of that being caused by severe braking as in stoppies. | ||
| Jerseyguy |
I'll have to agree with Blake & Thunder on this one. I've come down hard enough from a poorly executed wheelie to snap off a foot peg and I've never seen evidence of a rub mark on the chin fairing. | ||
| Lowflyer |
I agree with everyone. I have put mine through some knarly stoppies and had some poorly landed wheelies and have seen no marks on the chin fairing. However, I do think it is plausible to have fairing contact after a wheelie. Most wheelies are pulled while the bike is in forward motion. The Bike is usually traveling faster than the front tire is spinning in many cases by the time the wheelie is landed. If the wheelie is landed hard enough and the tire is moving slow enough relative to the speed of the bike, it is plausible that the resulting friction would be enough to momentarily overcome the inherent rake angle deflection. | ||

I'm concerned about footpegs snapping off from landing a wheelie. That shouldn't happen, eh? When I'm off road on my DRZ I'm standing on the pegs most of the time, I would think when off road on the Uly I'll be up on them quite a bit as well. I plan to get the Uly dirty soon. Do we need to haul spare pegs? What's up with the pegs? Or was this just a fluke? Jim in Santa Barbara | ||
| Lowflyer |
Sounds flukish to me. I have been pretty hard on mine. In my experience, the mounting bracket casting will snap before the peg. BTW, $150 and change for the casting. | ||

Jim - I was goofing around in my parking lot on my 9 and I gassed it a bit too hard right off of idle at like 1 mph. I didn't pop the clutch but I tugged up on the bars pretty hard and it came up too fast so I jammed in the clutch before it looped. It came down hard and my foot was more toward the end of the right peg. I stepped through the peg when it broke and did a slow mo lay down. My sliders saved everything but the front brake lever ant the mirror. If I was any good I'd have tapped the back brake and rode it out. I think it was more rider error than a weakness in the bike, although I have heard of others snapping pegs. On the other hand, I'm an old ex enduro rider and have crashed and burned in every way possible and never snapped a peg off though I have bent my share of them. | ||

"on my 9" That explains it - different pegs. I haven't heard of Uly peg breaking yet. Has anyone else? | ||

There was an early report over on ADVRider where a guys Uly was tipped over in the showroom and had the footpeg bracket break off... http://www.advrider.com/forums/showthread.php?t=97613 Seems to be a freak accident since other have dumped the bike at higher speeds and had no issues. I do think that there are some heavy-duty aftermarket pegs available, and if you're going hard core, you might want to upgrade. | ||
| Lowflyer |
I broke the left foot peg bracket on mine when it fell over in the grass at about 5-10 mph. The peg was unhurt. Bracket was $150 and change. | ||

From an engineering standpoint, it's easy to see why those castings will break in a tip over, and hold up just fine under a riders weight in a standing position. Castings are like concrete. They're amazingly strong in compression, and useless in tension. In a tip over, that casting is under major tensile strain, and under an impact tensile load such as during the occurrence of a tip over, it isn't going to hold up. No way. Moral of the story is, don't tip it over. |
