I have been riding my duke everyday and having a blast.getting bettter at wheelies did one for half a block.I love this bike.
I also have an RC8 which I have not owned very long.I want to track this bike and maybe start doing some club racing.The problem is both these bikes have brembo's which I love.My RC8 had rear brake problems from the guy I bought it from.We are going on the third rear caliper for some reason on the RC8 they are having some problems.the problem is the pistons won't push out in the begining.Please forgive me because I am not a tech guy like Nerd.We have to take apart the caliper and hone the thing so the pistons will move easy.Right now if you move them out a little bit by hand they will work and close on the disc.When they retract flat they will not come back out to push the pad against the disc.So the fix is to take the apart and clean them up so the parts move freely.This problem has been with this bike since new.Finally my friends at Santa Monica KTM saw the problem other dealers have worked on this bike but it never really was fixed well.Since there are not that many RC8's out there I thought I should say something.This problem will end up being a service bulletin.All 3 calipers were new and have the same problem.Brembo or KTM needs to do a better job.So sometime I hope next week i can pick up my RC8 and get some saddle time. Did a bunch of work on her and she is fast.I hope we can get a bunch of us at Chuckwalla in April.I will bring the duke and the RC8 The duke is running great and loves chucky.The RC8 I know will need some help in the susp dept.I promised the Nerd he could ride it so Nerd lets have some fun.I cant wait I am going to ride the shit out of it out here then put some new corsa's on her should be a blast I changed the gearing so it has more low end and less top end.I will never use it anyway.So If any of you guys have any problems with your rear brake like having to step very hard to get it to work that could be a sign.One is the duke is so easy to ride and at Chucky it seems to fly there.Th RC8 I find it harder to get used to but am looking forward to see the differance going thru turns at speed.I just hope I can ride it like I rode the duke.Can't wait to see how much faster I can go .I got some great input last time really helped many thanks to the guys on the forum.So lets see how many we can get out there this April and tear it up and have some fun last time was so great.This time I guess we will go the regular way so it will be new to me.John I hope you can go your the reason I got to do it the first time helped me a lot and your welcome to try the RC8 for a few laps.I never have a problem riding the duke there for sure.Just glad the weather is ridable hope to take the duke out a little wed for some twisty fun.I just want to get back on the track so bad it's all I think about.It's the only thing that clears my head from all the crap in my everyday life.Without it I would go crazy.

do you have aftermarket/KTM hardparts rear sets?

some aprilia RSVR riders have complained about the rear brake's function caused by the MCs orientation (horizontal). even after following the correct bleeding procedure - due to the bleed hole being at bottom of the caliper. after installing rear sets which relocates the rear master brakes improved.

can't see my RC8 right now but I think it's parallel to the ground as well. aftermarket rear sets will move the master so it's perpendicular

My rear sets are not stock. They are rizoma I like them they have several adjustments and do change the position of the mastercylinder.In fact the bike they use on there home page when you look up RC8 looks just like mine same color.This thing has been a nightmare.We changed out everything so all is new The M/C was bad maybe because it had to work so hard to move the pistons on the caliber.Who knows? We looked up the records and this problem has been going on since new.We are on the third caliper all were new from KTM.They even put the thing together on the bench before install and still did not work.Then My friend got the pads out half way by hand then they worked fine.Like I said when they went back to the flat position they could not get the pistons to push out the pads.So we are hoping that by honing out the area and making it easy for the pistons to move freely it will solve the problem.Some thing is making them hang up so they don't move in and out.It has been there for over a month.

Update got the caliper to work. but still not enough to build pressue to stop the rear wheel.So now it seems it could be a problem with the rear sets since they change the position of the master cylinder and use some differant parts.I got a call into Rizoma USA I can't believe that they make a product that does not work. Their website has a picture of my bike same color. In all my years of motorcycles I have never seen anything like this.All I want are my rear brakes to work.Do I have to go back to stock to make it work.These rear sets are made by a good company that makes all kinds of good stuff.They are not cheap crap.Has anyone had any problems with rizoma rear sets? I know many other bikes that use these and have had no problems.Please anyone have any clue to what the fook is the problem. Help!!!

Try hitting the ENTER key every now and again next time...

I don't know if its appropriate to address RC8 Issues here - I hope no one minds (?).

Really? It bleeds orange!

Maybe we need to get the mods to set something up for the RC8. I say this as I'm sure each and everyone of us has considered purchasing one of these things...I know I have on more than one occasion. Just last night I was up till......somebody stop me!

The more info we get in one place the better - imho. There really is nothing out on the interwebs worth a shite for the RC8/R. Would be good info to have as the motors are similar and typically pushed harder than most SDs. Just thinking out loud here.

So what parts did they forget to remove that made your rear brake in-operable to the point they spent a thousand dollars replacing parts to no avail? fooking idiots.

All KTMs are welcome here but there is a section in the forum called Other KTMs. This thread belongs in there and that's where I'm moving it to guys.

Thanks guys did not mean to stir up anything but I have seen so many things in differant areas.Other KTM is where I tried to go which sounds fine to me but I really never got any where.There are a handfull of guys that post a ton and I have met some and they have tought me so much about my duke.I do agree it would be nice to have something for the RC8 to mix it up with dirt bikes, adventure etc It just gets lost.This site is the best site for KTM period and I have tried to find anything or anywhere to go for this fine machine.It shares so much with the duke many parts interchange.I was at my end of my rope because no one knows these bikes only the people that ride them no steelers know them. They just don't see enough of them.I wonder how many are in the USA total.I will abide to the Klinks commands.When I ride the piss out of her in the next couple of week I will let you know how it goes.Trust me guys I feel lucky I can have both. I just hope I can ride it like my duke. The duke gives me so much confidence.The RC8 is just so fast talk about a hooligan.Good tracks days comming at Chucky .John it's all your fault brother you got me hooked. Get you ass out there try the RC8 out I owe all this to you.
