There are a number of us that would like a belt tensioner if there is anyone out there willing to make some like pictured using an xb pulley I am in and will help with design etc or if anyone has one I will buy it!!!!    | ||

To awnser jolly question for tension Jolly Posted on Sunday, December 22, 2013 - 12:58 pm: what does the pulley do for the belt? I mean, its obvious that it applies tension, but if the problem is that these belts break when over tight, what's the benefit of the tensioner? Doest it move the tension point of the belt closer to the pivot arm so that you don't have a changing length in the pivot arm which causes the belt to get tighter at its longest (perfectly inline with axle, swing arm pivot point and drive pulley) point? though to me it looks like thought it moves the tension point, its still lower and forward of the swing arm pivot point. jolly it provides consistant tension not added tension. with the tubers you run the belt very loose because when the suspension is compressed the belt tightens using a tensioner takes out the slack since the tensioner is fixed when the suspension compresses the pressure comes of the tensioner but since the swing gets longer the belt stays at the same tension. Know that being said it takes up slack and thise of us running longer belts and fixed axle modified swingarms could really use one | ||

Well, another parade I hate to rain on but, Erik Buell holds a patent on that use of a belt pulley (stationary pulley to provide belt tension on a motorcycle). Anybody making such a part will need to license it from him first. | ||

Only if we make it to sell for profit I want a one off. | ||

Two months ago I've been chatting with Marcello, one of the Freespirits.it guys. He said that they usually do not deliver to customers directly, but by means of a local reseller, preferably a workshop. Guess I've been pestering him so long that he gave in eventually.  It really isn't a tensioner in the proper sense. Since the front sprocket and the rear pulley are offset quite a lot from the swingarm pivot, you'd need to have some self leveling system to really tension the belt without risking any damage. This system is fixed, so you still have to make sure that the belt is properly tensioned "scary loose". Besides looks, the main advantage of this "tensioner" is, that it reduces the violent shaking of the belt while coasting. Ever taken a look down there at your belt when opening and closing the throttle in rapid succession? You can see in my pictures that the belt is nowhere near "tense" or "tight".

Dave thats perfect sent an email hopefully it is available! | ||
| Dave_02_1200 |
Keep us posted. It would be great if Twin Motorcycles can sell those. Those guys make some really cool stuff (I am planning to get their intake flanges with O ring seals). | ||
| Pash |
Willybuell will make you one... http://www.ukbeg.com/forum/viewtopic.php?p=232973# p232973 Pretty cool that people find they need one 17 years after the S1 was brought to market... | ||

Personally I'd be replacing the crappy shocker before spending the hard earned on unrequired technobling, but thats only my opinion. | ||
| S1owner |
Well 5-0 can get them apro 280 to my door. | ||
| 50dro |
^^^What S1owner said...Let us know if you're interested and we can find out availability and delivery schedule. Thanks!  | ||

I don't mean to knock this but let me see; so this belt tensioner will keep the belt under constant tension while the bike is sitting in the garage. Hmmm, let me think about that for a minute...As usual I must be missing something. | ||

I've broken two belts on my X1. Each time it was at very low speeds going over a bump. (Railroad track, speed bump.) I believe the suspension loading and unloading, which changes the belt path length, results in the slack in the belt being suddenly taken up, and putting enough instantaneous tension on the belt to snap it. I'm sorry for not explaining it better than that, but it's all I've got this morning. I believe the tensioner/idler will prevent this failure mode. I'd really like to see one with a spring in it, like they make for the XB. | ||

>"I believe the tensioner/idler will prevent this failure mode. I'd really like to see one with a spring in it, like they make for the XB." My 2008 XB12X popped its belt in the same circumstances as you described at 15Kmiles. My X1 also popped each of its belts in the same circumstances. I doubt that adding an idler wheel will help any. It may even do more harm than good. XB belts are supposed to be bent backwards but tuber belts, at least the original sportster styled ones aren't supposed to be bent backwards. | ||

Not to restart the free spirits tensioner discussion here, but know that if you use that tensioner you have to shim it to align it in the first place, and it has wear parts that must be replaced on a regular basis (and the service interval isn't that long). FWIW. | ||

I don't get it? I have been riding my M2 for 12 years now. I am still on the original belt and I have done track days, road trips, burnouts, wheelies, and even crashed the bike at the track resulting in the poor bike doing 3 summersaults. Other than looking different I see no value in this add on. | ||
| Buellistic |
Know what you mean as "i" have 111K on mine ... "BUT" this a tensioner will help make your rear sprocket and drive belt last even longer !!! | ||
| Pash |
Last time I broke a belt, it was doing a wheelie... Only time I wished I had a tensioner was trying to do wheelies with a new correctly tensioned belt, when it jumped. To stop the jumping, I would want a sprung tensioner, to guide the belt on to the sprocket. Willybuell's is sprung... | ||

Belt life seems to be a crap shoot for me. First X1 belt lasted 48,000. every one after that under 15,000. Chilly weather seems to play a role too. | ||
| S1owner |
Ok some of you are way missing what I need I am using an Xb swing arm on my tuber and it has a fixed axle so I will want this to take up slack when the suspension is on the down swing which moves the axle closer thus more slack in the belt as the axle swings up it increases tension naturally and at the same time pulls away from the tensioner roller. I would not need one iif I was not doing this. And please lets not get into the free spitrits spring tensioner talk if you do not know what I mean google it. | ||

Also I say Why do it? Because I want too. There is no better reason | ||

"Also I say Why do it? Because I want too. There is no better reason".. We also would have accepted "Because someone told me I can't" or "Because someone said I shouldn't"  (Message edited by trouble_enabler on December 23, 2013) | ||
| S1owner |
Yep that too | ||
| S1owner |
Ok so Twin motorcycles has them and you can get them there or from 5-0 it is 280 shipped aprox at least to my door that is so contact them if interested. | ||

38k 10 years strong on the 2006 XB belt. 139 teeth instead of 128 stock sporty belt. A couple times it was too loose and I just readjusted a little tighter. All good...no problems just not easy to pop a willie. | ||
| S1owner |
I ended up making one | ||
| Staps2 |
Could I see a picture I'm thinking of making a spring loaded one up using a car belt tensioner | ||
| S1owner |
You will be hard pressed to find the room for the mechanics of a car idler wheel set up. Plus you dont need the spring loaded if you put the pulley at the pivot point it will keep adequate tension through out travel that way. Here is mine notice the pulley is right under the pivot point. See the pulley mount hoke is slotted with an allen screw to adjust final tension and the pulley is a duramax idler wheel it is smaller then the xb pulley   |
