A bike standing up under braking isn't so much of a tire issue as it is a geometry issue. Changing tires can change the geometry in a way that it exadurates or eliminates the problem, but ultimately up to you to find a tire you like & adjust the geometry (if possible) accordingly.
Braking should actually make it EASIER to get the bike turned in as it compresses the front end making the bike more flickable.

Yea the XB and the Uly are of course totally different bikes. Besides don't you have the "long" version of the Uly FB? I have a stupid question tho',wasn't the perimeter brake system supposed to stop that very problem?

One of the things to also keep in mind is that there are specific tires designed for Buells. These OEM tires were designed lighter in order to reduce the unsprung weight and decrease the tendency to stand up under braking (per Erik Buell). The Diablo T was supposed to be lighter than the standard Diablo, etc. That was the lesson from the D208 which was, if I remember correctly, an off the rack tire. Other tires placed on the bike are not designed with unsprung weight in mind. I had the misfortune of strapping on a set of Tomahawks. The tires wrecked the handling. I felt the same about the Pirelli Stradas.
The D616 was specifically designed for Buell with both lightness and off road tread pattern in mind. It sucked, but that was the design spec'd specifically for Buell. The Uly is on the same platform as the XT, SS, and STT with the longer swing arm and higher capacity frame/tank. It is less likely to stand up under trailbraking. I'm not at all saying it doesn't happen, but I don't see it as the "holy crap this thing is a death trap" problem many make it out to be. It's hard for a bike to stand up under braking with you have a 240lb + Gear gorilla hanging off to the inside of the turn. The longer suspension of the Uly actually makes trail braking trickier simply because of the amount of travel in the front forks. It's much more sensitive to front braking inputs. I tend to trail brake with the rear if needed. The S, SS, and R models tend not to have the same dive and front fork issues under braking due to the shorter suspenders. I rode an 9R for about 150 miles while down in Suches. I didn't experience ANY of the standing up in turns under trail braking. Again, I doubt that the little R could even THINK about standing up with a gorilla hanging off of it. |

So, if say that gorilla was 6' 1''... oh say 315 lbs.... You think that little R would have any problems with standing up???? HAHA

Whats the difference between the SS and X?? I keep looking but I cant really see anything major....
Idk, i dont think i'm gonna go the buell route anyway.... if i would go with a twin i'd most likely go with the SV650 line. Maybe the S version with only the front fairing... so i dont fudge up the side fairings like all my friends did with thier first bike. Add em' later.... cause im definately a fairing person!

SV650, with no fairings, or the SV650SF with full fairings. You can't get just the upper anymore, and they dropped the 1K too. |

Of the "long" models, the STT is the best handling of the bunch. It came with upgraded suspension components. The X has the longest travel suspension of the bunch with approximately 1.5-2 inches greater travel than other models in the line. The X has nearly 7" of ground travel for use in light off road duty. If'n you aren't a galoot, the S, Scg and R have a much quicker geometry and will turn quicker than the long versions. The long versions are more comfortable in that the seat rails are longer and provide for more seat to peg distance. The SV line is very good, cheap, powerful, good handling, and provides many after-market options. Parts are cheap. You can probably build one from spare parts at a track day. The Buell is very good, cheap, powerful, good handling, and provides SOME after-marekt options. Parts are cheap. You will probably be a party of one or two at a track day. I tried both the SV and Buell when I was buying. Although it was a good engine, the SV didn't speak to me. You are either a Buell person or you aren't. Test ride one or two and you'll know. For me, the Buell was the closest thing to a '69 Chevelle on two wheels you could get. It's just angry and grunty and loud. For me it was comfortable like no other bike is. After riding 150 miles on the R, the X reminded me of why I picked it. The X just fits galoots. |
