• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Belt Stabilizer

I have heard a lot of native things about the BRP Belt Stabilizer and very good reviews on Doc’s Belt Stabilizers. I see Baker makes one also that looks good but I have not heard anything about it. Is any one using one on here? I have not notice hardly any vibration on my 2015 Roadster RT but I have been thinking about installing one. Is Doc’s the best one?
 
I have BRP's but it looks cheap. Doc's looks more robust. Don't know if it is better, per se, but it looks higher quality.

I retired as a mechanic and a tool & die maker and I feel Doc knows what he is talking about. I was just wondering about the one Baker has.
 
Belt Stabilizers

In a nut shell the BRP unit is made of plastic, only has a single bearing centered in the pulley. Meanwhile the unit by Doc and Baker are made of metal and have two bearings with a larger diameter pulley, much superior in construction to the BRP unit. A larger pulley has a lower rotational speed at any speed than a smaller pulley. The serpentine belt on your cage has a very sturdy tensioner pulley and arm, no plastic! I would not recommend the BRP unit, my $.02 worth.
 
As I see it....

Only offering my opinion here... but of the three I think Doc has the better one. :firstplace: I have a smoothspyder belt tensioner myself...

I wonder about the one from Baker also.
It seems to mount differently than the others.
Does the Smoothspyder mount with tension placed on the bottom of the belt?
 
so how does it do compared to doc's or baker?
from reading here, it's my understanding the top mounted damper gives the best results--
just wondering

I can't compare the SmoothSpyder to Doc's or Baker's, as I have never had either. But my experience with the SmoothSpyder (and I have the original one, not the newer version) has been very positive. A quality product, very well made, and dependable. I have had mine for 4 years with no problems, and it really cured the belt vibration. I recommend it.

I don't think the SmoothSpyder will work on the RT.
 
I had the smoothspyder on my 15 RTS. It worked good. I have docs now. It works good also. I seem to feel more of the engine vibe now but not belt vibe.
 
Yes it does. You have to get the one made for RT, if Jim has them in stock. I had one on my 2013 RT and now have one on my 2014 RT. It and Baker Air Wings one were the only ones available 4 years ago.

I bought my SmoothSpyder on 2/18/14. Installed in March same year. So not quite ​4 years ago, but close.
 
I have had my smooth sypyer on my bike for 2 1/2 years now and it has made 0 difference in the vibration. I put Doc's on about 6 months ago and now i have NO vibration. GO DOC
 
I am experiencing intermittent vibration in our 2014 RT. From reading several of the comments here and on other threads, it appears the DOC's is the preferred choice. Where would those be available? Are they a DIY install for someone who has been turning wrenches on motorcycles since 1968?
 
I have the BRP idler on mine, no issues and it works fine. I have upgraded the pulley to a double bearing for longevity. I had a lot of vibration since i have the ISCI floorboards, the BRP cured the belt vibration i felt in them.
 
Has anyone had both the BRP one and Doc's one to compare the two? Setting aside the quality issues that several people have had with the BRP one, is the desired result the same, or does Doc's work better at eliminating the vibrations?
