Okay, I'm sure this data is spread among about 20 different but similar threads, some of which I've found..........but I would like to know any or all the differences between 2004 vs 2008 firebolt. I'm leaning towards the 1125R, but the new Firebolts look sweet and seem to have some nice improvements over my 2004 Firebolt (which I love but want upgraded. I would like to start a list of differences and I know a lot of folks on here know them from the top of their head. Thanks for the help | ||

Not enough that it would scare me away from any of the years. | ||

I agree, but my mileage was getting high on the 04 bolt so I'm really try to pick the best bang for the buck on all the bolts if I don't go with a 1125R. I know of some great upgrades like fork Dia, Oil Pump, More fuel in the frame, diff swing arm, much improved belt.ect... Just didn't know if I missing much on these upgrades. Thanks for the input. | ||

The lubrication to me seems like the big one. Advanced from the RR. I do believe the tranny changed too in 05 or 06. Buell also added some better air flow with a screened front filler cap area in the new air boxes too. Again, 05-06? If you had your heart set on new, I'd go new, but I have an 03 and I'm happy. | ||

The clutch change was in 06. I had to put the Muller in my 05 (well worth $160). I thought the screen in the filter cover was 07. | ||

08 all the way no doubt about it. It has everything the previous years have and then some. Better oiling, 300 RPM higher to 7100 and to boot its $500 CHEAPER. 1125r looks Killer but I AM NOT A FIRST YEAR BUYER------EVER! I always wait two years so they get most of the bugs out of the bike. | ||

300 RPM to me is really nothing to brag about. The clutch can be fixed by updating the to the 06 clutch spring's and using different HD fluid. The belt is a no issue at all.... We've seen all years break. You can put the better oil pump gear in. As far as the larger ID fork's??? Can anyone on this board tell the diff ??? I doubt it. They have upgrades no doubt but all the XB series bikes and years have all been pretty good bikes as a whole. | ||

To me 300 is nice but your right not a big deal. The clutch spring WELL your just spending money where you didn't need too. But the oiling system is more than just a GEAR its an entire oil pump upgrade. Oh and and what about the new fuel injection system, NO MORE TPS RESETS! Money saved to put towards an upgrade.

So, are you saying the '08 TT will not have the offset triple trees to give more steering lock? I'm looking at an '07 TT right now, but would consider waiting for the '08 if it has more steering lock. The salesman didn't know, and had no '08 brochures left. I also considered the Ulysses, but it seems a lot of the things added to it over the TT were to make it more touring capable and I already have a touring bike. The new Ducati 1100 Hypermoto is also on my short list, but I'm concerned about fuel range. Is the TT at all gravel road compatible? All the above improvements look great, but a few leave me with questions. Was oiling an issue on street ridden bikes? Are the larger crankpin, etc., necessary for street reliability? I get the impression from lurking here for a while that these things are already pretty bullet proof. Do the crankcase "improvements" essentially mean now that the cams, etc., run directly on the cases and an oil related failure or the like now means you replace the entire side case rather than bushings? Is this the end of the rebuildable Buell? All of which is a long winded way (sorry) for this noob to ask; If I have no problem with occasionally resetting the TPS, and the '08 TT doesn't come with the new offset forks, is there really any reason to wait for an '08? Thanks in advance for any input. |
