Anyone using one of these?  They are sold by Trojan Horse. Seems like a good idea for relieving the belt tension under high stress to help prevent belt breakage. Mike. | ||

saw that one myself, really like the loocks and idea of it, just haven't got one yet. kind of curious about that additional bracket with the reverse 5 on it. | ||

VERY nice  . | ||

the bracket is to support the chin fairing, look ma, no buell can.... | ||

That bracket is probably a fairing bracket or something similar, nothing to do with the pulley assembly. Cya Stot | ||

The original idler pulley on the XB's in intended to provide a particular level of tension for the belt. The belt supplier recommends using the belt in an always tensioned state for best longevity. Buell spent significant analysis time determining how best to tension the belt and at the same time keep a tension that remains relatively constant. The spring loaded thing in the picture is a no no. mikeyp | ||

Mike the spring loading is there for those that like to do stoppies. When the rear suspension unloads during a stoppie the tension on the belt goes bye bye. Otherwise the pulley maintians the same measured tension on the belt that the factory pulley does per the information on Trojan's site with regards to that pulley set up. By maintaining tension on the belt when the suspenion unloads it keeps the belt from snapping when the tensions snaps back on and the throttle is snatched after a hard stoppie. | ||

I was under the impression that the idler pulley size and location was a calculated compromise. | ||

I have one on my 9. I thought that it wasn't making any difference at first but then i started to be More agressive with the throttle (Gradually building up to last year's speed)and realised that the bike is much smoother, on the power, out of ripply apexes. I guess the suspension is able to do more work if it isn't fighting belt tension? The bike is much easier to push around the garage, too. I think that the euro models may have a different pulley to the US ones, following a spate of failures when early final production models were tested by Journos. I know that someone will know the truth of this. A modification like this may have its own limitations and so could possibly be less ham-fisted-user or production-friendly than one fixed piece. I like it. | ||

I wish they made one for tubers. I hate having to run my belt so loose. | ||

I should have included the product description in my original post: The stock Buell belt tensioner is designed to keep the belt under constant tension, except it doesn’t! When the suspension is completely unloaded, such as when pulling stoppies or even braking hard, the tension is increased to an alarming degree, which can actually damage belts, wheel bearings and pulley bearings. This spring loaded item is designed to maintain a tension of 10.5kg regardless and will help lengthen belt and bearing life. Extensively tested in competition this is a must have accessory. Utilises stock tensioner wheel. Martin, thanks for your input. I was under the impression that the idler pulley size and location was a calculated compromise. That's what I thought also. If the product description can be trusted, then it would seem this device would be an upgrade over the stock tensioner even if you don't do stoppies. It's not too terribly expensive, so I may give it a try along with putting in higher quality bearings in the tensioner wheel. Mike. | ||

The belt gets too tight when the rear suspension is unloaded? Like everytime you put the thing on the sidestand? I don't buy it. I can see how the swivel pulley bracket could help improve rear suspension performance though. | ||

Marketing promotion only. The stock setup maintains extremely close tension control through the whole range...there is a massive amount of design work in the geometry. The reason the UK journalists broke a number of belts early on is that the original '03 Gates belt is very sensitive to mishandling, and the belt failures were after the magazines tossed on new tires at dealerships who did not know how to handle the belt. The latest Gates replacement is better, and the '04 Goodyear way better. The tension has to be tight or the belt will skip out of the sprockets under hard downshifts, etc. | ||

Lets put it this way, I'm not mechanically inclined, I have changed my rear tires twice, messed around with the original belt numerous times, tryed stupid things on my XB-like wheelies, and track days-not that track days are stupid, and I have never broke my original belt! Why would I want to spend more money on a modified belt tensioner? Gotta go, see ya when I see ya! L8R, JM | ||

anon....i love how you used the word"tossed" on that..... | ||
| Xb9er |
That's cool. As I said above, I was wondering whether or not the product description could be trusted. Now I have the answer! It seems my money will be better spent on a new Gates belt (the Goodyear is only for the 04 XBs, right?) when the stock one needs to be replaced. The Badweb is great. The only Sportbike forum where I get answers I can actually trust!! Thanks anon et. al. Mike  | ||

There were multiple pages of math equations to design that pulley setup. I remember talking to the proud engineers about it. Tat from American Sportbike also knew about its design. It was quite interesting. I'd take Anonymous' suggestion. | ||

Just to clear up a point, when the anon is in black, is it THE Man? If it is, there's no point arguing any more, but I still like the little yellow springy thing! | ||
| Davefl |
Just because it is the Anon does not mean it is "THE Man", but it could be. He has been known to chime in from time to time. Only Admin knows who it is and Blake is good about pointing out people who abuse the feature. | ||
| Blake |
When the "anonymous" is in black it means you have clicked on the "anonymous" tag hyperlink. Trying to guess who is anonymous or which "anonymous" is posting would be futile. | ||

There goes my conspiracy theory about Erik being one of the Men in Black! |
