Is it worth fitting SpyderExtras Billet Aluminum Belt Tensioner/Idler?

[chunkmonk]

Went through SlingMods this morning, since it's Memorial Day and the wife told me to pick something out for myself... I went through and picked up a few goodies (Neutrino Aurora Plus will be back the first week of June!), and also made a short list of things that look interesting. I just wanted to get the forum's take on these - pro/con/meh

I've read that belt tensioners/idler are a must for spyders. Not sure how they work. I've had tools that help tension a belt/chain on a two-wheeler, but I'm not sure how this is working in real time. But - are they worth it? Are there known issues with them? Is one brand better than another? I appreciate the valuable input!

You're going to get a mixed review on this one, some like them and think they can't live without it, some, like me think just lowering the belt tension works good enough and it will not wear out and blow your belt! Good luck!!:2thumbs:

Agree with Mikey, on this one, If you don't feel any vibrations at whatever speed, there's no need for an belt adjuster, if you experiance vibrations, try and set the belt to a lower tension, there are lot's of video's bout this particular subject.

:agree: on both things ..... and there are more than just a few folks who have discovered what a FAILED belt Damper can do. To me the Spyder is a Motorcyle and shouldn't be expected to be PERFECT. .... Yes there are things you do fairly in-expensively to improve it, but I don't own a Damper and never will ..... good luck .... Mike :thumbup:

Thanks for the responses Mikey. Pirate, and Mike... I have read a few stories about a failed tensioner. Not pretty. Part of why I asked this question before throwing down the ~$200USD for one. It would be interesting to know if anyone on the forum used one and then removed it. I've not felt any vibrations on mine, so I'm not willing to jinx my ride by looking for a solution for which there is no problem. Thanks, all!!

Having a 2019 F3S, my machine came with a tensioner. I currently have the SpyderExtras tensioner installed. It is a very stout piece and very nice quality. The roller isn't as beefy as the Lamonster roller (used that on my OEM tensioner), but the SpyderExtras roller is a nice upgrade over the OEM. Just some FYI ...

Thanks, Troop! Does the tensioner prevent problems or is it designed to correct a problem? I'm not entirely sure from the description of the products. Thanks.

IMO, a tensioner has one more spinning part that can fail. While my Spyder is older than yours and a different model, the principle and failure risk remains the same. I've not sensed vibration in 78K+ miles so I've never considered one. FWIW, the Spyder tech at the dealership who has mounted three General Altimax rear tires always checks the belt tension with a Gates electronic meter.

Waste of money.

I've never noticed any kind of belt vibration on my F3S, but then again, my machine came equipped with one OEM. For that reason, I will not remove it. That said, I also went aftermarket, as they are quite a bit more stout than what comes on the machine.

It simply applies pressure to the top side of the belt and kills harmonics that tend to only effect certain machines. Get out on the interstate and do a slow acceleration from about 50 MPH up to 90. If at no point do you feel a very jarring vibration working up from the bottom of the bike you simply don't have a problem and have no need. If you do, start adjusting the belt tension, with luck your problem will be solved. If like mine it just moves the speed window for the vibration starting and ending points and it never goes away, the device works. I use the one from Lamonster. In 40,000 miles + I have replaced the roller and bearings once, more for peace of mind than actual need. I do make a habit of reaching under the bike every coupe thousand miles and lifting the roller to check the bearing and roller face.

If your belt tension is set at a BRP dealer shop, I can guarantee it's probably double what mine is set at ( and I have no vibes )..... just sayin ..... Mike
