I think the main reason its getting fixed this quick is because current and past employees from Buell read Badweb. They talked to each other and BADA BING its getting fixed..... |

I had a friend of mine that M2nc is gonna know. He's not part of this board or ANY Buell associated board for that matter. He used to race bikes for years and used to own a dealership here in the local community and has worked on them all. He's the only 6'9" goliath on a TDM 850 that you'll EVER see. I ride with him on Sundays usually, and he has never owned a Buell, and reasons for that are even longer and have issues that go back 20 some years as I once heard him try to explain to me one time. He loves my bike. Says great things about the XB's and Buells in general, but has a problem with what seems to be other personal sides to the issue. That being said, he's been in this industry for what must be 20-30 years now, and does a lot of experimenting with bikes. I asked him on this very question, and he replied in perfect Mike Morley fashion. Long and detailed. He, over the course of MANY years has written articles for other magazines and has a lot of years of data and experience. Most of us that know him seem to heed most of his advice. Is he the end all be all of knowledge? No. But pretty damn close. To know this guy is to love him. He's a bit spacey at times, but a great guy none the less. From MadMotoMike: "the belt drive is the way to go. Shaft drive is good if you have a engine orientation where the crankshaft is longitudinal. Shaft drive is a natural in this instance. Chains used to be unreliable. When the kaw z-1 came out ;kawasaki was replacing chains under warranty, the chains needed constant adjustment, as a result shaft drive became popular. The problem with this is that shaft drive eats a huge chunk of horsepower due to rotational mass. It also adds a big chunk of mass right at the end of the swingarm, thus having a negative effect on suspension action. The springs and damping necessary to control this mass under aggressive use, render the suspension somewhat non compliant. Lastly , if you have a problem with the shaft drive; it is a big problem. Ex... the seal in the final drive failed on my bmw. The seal was 28 dollars but it took a couple of HOURS and special tools to get it installed. Plus, any gearing changes with shaft drive are limited and must be done with the height sidewall / circumference of the tire. Ex... a 130-80-18 is effectively gearing the bike about 300 rpm shorter. Chain is good because theoretically it is very efficient. The theory is sound, but falls on its face in reality. Ignorance and wives tales cut the thing off at the knees. Most people do not know that the chain slack specification is a MINIMUM spec. They do not realize that the with the bike laden, the chain should never be tighter than the specification. Do you have any idea how many chains i have seen that were strung like piano wires??!! In any given moment, with any given group ............at least 60% of the chains will be misadjusted. 99.9% will be way too tight! This saps horsepower, destroys components, wrecks the suspension performance/handling, and generally "BINDS" the bike up in all kind of negative ways. Good news, is that it is compact and saps little power when set up correctly. Belt drive is superior, it is not perfect. The good: efficent operation, lightweight, extra protection for the transmission (driveline shock.) It can be set up with NO adjustment available.(this means there would be no possability that people acting on good intentions could get it misadjusted.). Its clean and lubricant free. If it ever were to fail, it would tear up less stuff than the other two. Also its negative impact of the bike's performance and handling is minimized. The bad: bulky.....to get the pound per inch loading in the correct range; the pulleys must be big in daimeter and wide. They also work better on short wheelbase applications. Does not work well in high traction, high torque applications. Example: A belt drive hyabusa would need an extremely big set of pulleys to keep the ppi in the safe range. This is gonna sound strange, but your bike becomes more vulnerable to vandalism. A bad person with a sharp knife could absolutely ruin your trip. I have bikes with shaft,belt, and chain. I like chain the best, with belt drive a close second. Shaft drive is ok but it is expensive and requires alot of compromise ... I like to change my gearing and do a lot of experiments. Not possible with belt drive and limited with shaft. Chain problems will take less than an hour to overcome on the side of a road. If i owned a belt drive bike, I would do research across industry to find a belt that is strongest and least expensive. If the stock one is the best i can do; then I will carry a spare and know how to install it. madmotomike does not like trip interruptions.. Of the three, belt drive is the least likely to be messed up by consumer error. Shaft drive is okay but murphy's law has a good foot hold. Chain is potentially the best but requires commitment, discipline, and knowledge to keep it working efficiently. madmotomike" |

Mitigating the shaft drive 'eating a chunk of horsepower' argument is the fact that 2007 model in line fours make so much power it simply doesn't matter that the drive eats 10-15% - or whatever - of it. torque slap and any gyro effects are all but eliminated now too. FJR1300 eg. |

Right now the only manufacturers making shaft drive bikes WITHOUT the jacking effect is BMW (all models), Moto Guzzi (all models) and Kawasaki (the Concours 14). All other shaft drive bikes have the shaft-jacking effect, some worse than others. Shaft drive does add unsprung weight, but most shaft driven bikes these days are big and heavy enough that a little more unsprung weight doesn't make that much difference in handling. Bending the power delivery around 90 degrees robs power and if you have to do it twice, then you rob that much more power getting to the rear wheel. However, BMW boxers, Moto Guzzis, old-style BMW K Bikes (not the new ones with the transverse 4s), the Honda ST and GL bikes only have one 90 degree bend in the power delivery (at the rear wheel). |

I've done pretty extensive tests on M109R Suzuki, C90T Suzuki and FJR1300 Yamaha recently. Clunky in first gear - but no 'jacking' at all did I notice on any of them. |

I would not expect any of the other big bike manufactures to take care of you to the extent of Buell. Again it is a dealership issue, when they have racks and racks of chrome bobbles you would hope they have a, gotta have it now or it won't run part, on the shelf. We need to remember we have a huge consumer advocate here. Thanks Court. I hope you get recognized for your contributions to the company. Your efforts are more valuable than most people realize.

From personal experience, if you have a BMW you better have a good dealer, because BMW North America is absolutely WORTHLESS at the consumer level. And even if you do have a good dealer, expect him/her to be fighting with BMWNA all the time in order to satisfy your warranty claims. And finally, just because you have a good dealer now, doesn't mean he'll necessarily be there in the future because BMWNA has been closing down dealerships left and right lately. I love their bikes, but the company itself sucks BIG time. |

Didn't Harley make a "spare" belt for their first belt driven bikes back in the late 70's. If I remember correctly it had a longitudinal "V" section that lapped into an equal "V" groove with little pins that slid into the hollowed out cogs of the over lapping "V" area of the belt. No wheel removal necessary either. It was the equivalent of the "mini spare", enough to get you home if you were concerned about having a broken drive belt. |

i wonder if anyone here bashing shaft drives has looked under their car or pick-up lately? i put a lot of miles on a shaft-drive FJR1300, and can report with the confidence that comes from actually having owned and ridden one that there was absolutely zero "jacking," on throttle or off. as for sapping horsepower, well the damn thing made 126 to the ground, and 90 pounds of torque (Motorcyclist magazine numbers), so, like, it kinda really didn't matter. as far as adding weight, i.e. "It also adds a big chunk of mass right at the end of the swingarm, thus having a negative effect on suspension action. The springs and damping necessary to control this mass under aggressive use, render the suspension somewhat non compliant", dude, sir, you have obviously never ridden an FJR in anger. ride to lean, FB |

I'm pretty sure that Mike was not trying to "defend" or "bag" on Shaft Drive bikes. At all! I merely posed the question that has been showing up lately on more and more posts which has eventually made it's way to this one. Some of you are focusing on the FJR1300. Good for you. You probably should since no one else is. |

>>Good for you. You probably should since no one else is.<< I'm not - it's just one of 3 particularly impressive shaft drive units I've tested in recent months. The m109R Suzuki was just as good. In big heavy 'trucks' they are great. I lived with the Rocket III for a while and found its drive just as un-noticable. But I wouldn't like one on my Uly. |

i find madmotomike's thoughts on shaft drive interesting. madmotomike: "The problem with this is that shaft drive eats a huge chunk of horsepower due to rotational mass." define "huge." and on today's shaft-driven bikes, does this "huge chunk of horsepower" that is "eaten" by a shaft drive really matter? it didn't seem to phase my FJR any. mmm: "It also adds a big chunk of mass right at the end of the swingarm, thus having a negative effect on suspension action. The springs and damping necessary to control this mass under aggressive use, render the suspension somewhat non compliant." "somewhat non compliant"? that's somewhat funny. mmm: "Lastly , if you have a problem with the shaft drive; it is a big problem." WHAT big problem? when was the last time anyone here saw a late-model shaft drive bike on the side of the road because of a "big" problem with shaft drive unit? how often does the shaft drive under your car or truck have "big problems?" would the fact that a car or truck has shaft drive keep you from buying one? how many chain or belt final drive cars or trucks are there on the market to choose from these days? mmm: "Ex... the seal in the final drive failed on my bmw. The seal was 28 dollars but it took a couple of HOURS and special tools to get it installed." this doesn't sound like a "big problem" to me. what year was/is his BMW? what model? how many miles when the seal "failed?" how did it "fail"? catastrophic, tearing up expensive hardware and stranding him in the middle of Death Valley? or, was it just weeping a little bit? how had the bike been ridden during those miles? any off-road miles? how does the "couple of HOURS and special tools to get it installed" compare to the parts and labor to swap out a chain and sprockets or belt and pulleys? i know you can't buy a chain or belt for $28... mmm: "Plus, any gearing changes with shaft drive are limited..." geez, honestly, how many of us give a rip about changing the gearing on our bikes? mmm: "Shaft drive is ok but it is expensive and requires alot of compromise ..." expensive? compared to what? "alot of compromise"? i'm missing something. mmm: "Shaft drive is okay but murphy's law has a good foot hold." what does THAT mean? Some of you are focusing on the FJR1300. i am because i have actually ridden one. the comment above "Right now the only manufacturers making shaft drive bikes WITHOUT the jacking effect is BMW (all models), Moto Guzzi (all models) and Kawasaki (the Concours 14). All other shaft drive bikes have the shaft-jacking effect, some worse than others" is WRONG in regards to the FJR, and, per Danger Dave, wrong regarding several other late-model shaft-drive bikes. chain is cool, have had a lot of bikes with it. belt is cool, have had a lot of bikes with it (including my current ride). shaft is cool, have had three bikes with it, and wouldn't hesitate having another.

i know you can't buy a chain or belt for $28... Actually, not that it pertains to your shaft arguement, but I can buy a non o-ring 530 chain for as little as $12.00 and thats for 100 links with a master link included. ($13.79 for 110 links which is the length I run) It doesn't last very long (1000 - 2000 miles) But it would get you where you needed to go. |

Shaft... chain... belt. 3 engineering solutions for the problem of power transmission. Each design has advantages and disadvantages, but there are no absolutes, and always some overlap between the methods. Choice of design depends on the best fit between the set of requirements for a particular application and the set of advantages/disadvantages provided by each design. When an engineer makes a choice like this, there is always a trade-off. No single design is best; you just have to do the best you can. For a lightweight medium-power sportbike, the belt is a very attractive solution. It is feather-weight, clean, efficient, simple, reliable, maintenance-free, and the zero-lash feature provides the sporting rider with a precise "feel" to power application. Thus I believe the Buell engineering team has indeed chosen the best-fit solution to their problem. Other design teams will choose differently depending on how they weight their design requirements. Knowing that the belt drive used by Buell has been thoroughly engineered and tested and revised at least once, it is still surprising to read of the occasional sudden failure of the belt. I have the feeling that this a now a pretty rare occurrence, but that it happens at all makes my right eyebrow raise up slightly whenever I hear of it. Aside from severe belt damage caused by entrapment of sharp stones, is there any other failure mechanism involved here? Have there been any failures attributable to manufacturing defects? Is the newest belt design still vulnerable to mishandling during installation that results in hidden belt damage? I pose these questions to Buell and Goodyear. I have no access to solid information, just anecdotal stuff from reading on the Badweb. What is the failure rate in the field, and what is the cause? Having said all that, I still would never trade my XB's belt drive for a chain or a shaft. |

as a number have said, all three transmission methods have the advantages and disadvantages, both theoretical and real-world based . . . . toady, my ideal choice (having, in fact, seen shafties on the side of the road immobilitzed by shaft failures) is chain -- due to two factors cheaper/easier gearing changes easier replacement potnetial road-side repairs (if the failed chaing doesn't take out the engine, as it has on my, once, long ago) if there was a limp-home belt option for my MaDeuce, I'd likely swap back to belt |

Oh My God... Are you saying that modern day Shaft Drives are impervious to failure? Plus, are you honestly saying that hardly anybody cares about the other gearing possibilities of our bikes? You must not have read that entire email... If you did, you'd have seen that I said that he used to Race bikes. (After a nearly fatal crash, he has stopped racing) So, I suppose I could still see his need to want to tinker and change the gearing on bikes. If you raced... would you race your FJR or any shaft drive? All the statements in the email I suppose were mostly from a racing point of view. You'd have to know him to understand, I guess. I would even go as far to say that IF you could EASILY change the gearing on any Buell... More and More riders would do it. Especially on the ULY. I could envision Knobby tires and an unmolested forest. |

Having owned all three variations I can report that I've seen/had more belt failures than the other two combined. I had a belt fail on a Sporty and Dad had one fail on his FLHS. The Sporty wasn't so bad to change but the big twin required a lot of tear down(like a Buell). It's something that could not be changed in a parking lot with hand tools. I have been stuck at the roadside with numerous Buell belt failures. None of my own but still when one bike in a group breaks down it forks up everyone's day. I have nursed several failing chains to a place where service could be performed. I've seen a few chains snap but all were related to poor adjustment or maintenance. I've yet to see anyone nurse a failing belt to a place where it could be changed. I never had a shaft failure although I heard the early Honda PCs had some issues. I currently own a Vic with a belt. While I'd rather have a shaft or a chain at least they've thought it out well enough that it could be changed roadside if the situation demanded it. |
