Front drive sproket

[mcurtright]

I have seen a ton of posts on f3 about this
but none on rt so here goes. I have a 15 rtl
the splines on front drive sproket stripped out
luckily mine was under extended warranty
bill was almost 700.00 if your bike starts clunking
like a harley every shift or makes a weird growling
noise you may want to get your sproket checked
picked mine up yesterday all noise it has bee
making are gone

Your right...

This is not particular to the F3. I posted when it happened to my RS and there have been many others not only F3's. I was way out of warranty but found all the parts needed and cost was about $200.00 with the rear wheel bearings. But I also do all my own work....glad you were covered...:clap:

Ok I did a search couldn't find anything pertaining
to the rt. Just letting everyone know,I also like doing my own maintenance
but place I bought it from suckered me into a
maintenance plan so until it runs out they can deal with it
thanks

don't have an RT.
but given the history of the F3 and other Rts, I think pulley/sprocket inspections are worth doing every 1500 miles.

Look for red rust. If it is there, the sprocket will fail at some point. Get it replaced. From what I am to understand, any sprocket showing the red rust under warranty will be replaced by them.
Since I have a F3 and an RT I purchased a replacement sprocket and bolt for about $115.00 from CCP. I inspect mine about every 2-3k miles.

Does anybody have a picture of what we should be looking for when we inspect the front sprocket? I can climb under the
Spyder and look but got to know what to look for. Also at what mileage are these starting to fail or isn't there a set mileage?
My 2105 RTS has almost 22,000 miles and I have never looked at my front sprocket. Thanks

Good to know. Just to be clear, we're talking about the belt drive sprocket? I have an RTL also - not too easy to inspect that front sprocket; any advice on that?

So what is wearing? I guess its the sprocket itself since it is probably made of just regular metal and not hardened like the shaft. Just what is happening to make the sprocket wear? Is the fastening bolt getting loose or what?

The sprocket is formed as one piece and the spline assembly is pressed into it. This gives them the ability to temper it differently than the sprocket. The reason they do that is so that it will wear out instead of the shaft, which would be extremely more trouble and big $$$ to replace than the sprocket. Somewhat like the softer metal on a starter drive instead of the flywheel being soft. Easier to replace the drive or starter rather than the flywheel.
Some of us believe that the hit and miss failure of these sprockets is due to some of them not being tempered properly. Being too soft and then grenading.
I personally have a 14 RTS and a 17 F3 Daytona and the RT has 48k miles with no wear showing (just serviced last week) and the Daytona almost 20k with no wear showing. The one I was personally involved with that grenaded in traffic was a 16 F3 Ltd.
Some ryders have reported replacing several......

I have posted my experience on another thread, but the Sprocket is being replaced on my 2016 RT Limited, which was makng a grinding and whining noise at 21,500 miles. It is scheduled to be replaced Aug. 12, 2018.
