2013 Camhead R1200RT-P
44,000miles

For about 3 weeks now I have been developing some worsening transmission issues.

It started as a very loud grinding and clattering sound whilst going over a bump at 10mph outside my house.
From then on, I noticed allot of strange noises that where not there before.

Firstly there was a sound like a metal spinning top being used on a stainless steel table top whenever I pulled the clutch in.
Then the Whirring noise started..... Gradually over the first week. Usually only in gear one whilst accelerating. Then it started whining on deceleration when in gear all the time.

Two weeks later I pull the tranny oil plug and find noting too out of the ordinary. So I put some fresh oil in for good measure.
Two weeks later and I go out in the morning to start her up..... And I'm rolling down the road. Can't shift up into gear two.... can barely shift up into neutral.
I have to put my right hand on the clutch lever and use my left arm to yang the bike up out of 1st into neutral.

I yank the shift lever up and slam it down 20 times or so.... and then I can just about get the leverage required to force the lever up into 2 whilst rolling.
Then about 5 minutes of riding later, she shifts as normal. No issues at all. It only happens when the engine is cold.

Sure enough same issue every morning from that day forward! I have to yank it like i'm unjamming a rusty machine gun to get it to move enough to shift by foot.
Once the engine reaches operating temp... It has no issue shifting at all!

So I pull the tranny oil plug again.... and it looks like silver acrylic paint!
So I drain it and find a fuzzy mess on the magnet....
I replace the oil again.
And then I come here for advice.

It does whine in almost every gear all of the time now.
Here's a vid of the noise.
Now granted it is a pretty cool sound.... Maybe someone threw a turbo charger on my RT whilst I wasn't looking!?


Are we looking at a circlip bearing failure perhaps here?
Is my RT trying to transform into a Stuka!?

The crying shame here... is that if I fix it... my RT no longer sounds like a RR Trent1000

Bearing failure, best stop driving and repair, if you keep driving you will end needing a new/used tranny

More than likely the input shaft bearing in the transmission, my LT sounded just like that. Input shaft bearing was bad.

I did it myself and the bearing was only $36. Yours is $56 but your transmission is a different style than the LT so it may not be what it is.

Good on you for having the guts to do it yourself.
Did you need any special tools?
My concern is that I may have already buggered the box beyond repair.
What are your thoughts on this? Maybe I should just throw a used low millage box on it?

If you are not seeing large shiny flakes on the magnet you are probably OK. Going into a transmission is not for the faint of heart and may likely require some special tools and application of heat. I had everything I needed as well as setting the end to end clearance on the new bearing. If you can find another gear box that may be the better way to go.

Okay sure, great. No large flakes yet.
I will see if I can get it to a Specialist for a bearing replacement then.
Thanks for your help. Really appreciate it.
