S2R 800 tranny problems

I don't know if it's the bike or my riding style, but my bike has had the same transmission problems twice.  The first time I had this problem, my bike would shift from 4th directly to 6th, sometimes hitting a false nutral.  This was about 8 months ago and I had it repaired under warranty.  At that time they told me it was a broken "shift fork."  This was about a month after my 6k service.  Now it is doing it again, ironically 2 months after my 12k service, and now 2 months after my warranty is up.  This time, when I downshift from 3rd I usually hit nutral, which is a scary feeling when you are expecting engine braking.

Anyone else have these problems or are my problems isolated.

The parts I know as shift forks are inside the cases, they mate directly with the gears, and move them in and out of engagement.
Did they split the cases to do the repair?

I haven't heard of many (any?) transmission problems like yours.

There are adjustments to the shift mechanism that can be done, perhaps that may help.

I have the same bike and have also had a few small issues. It has gotten stuck between gears, mostly down shifting from second to first. But no false neutrals.

Easy steps to take but the get it in gear and get back to the dealer.

1. is your shifter adjusted to fit you? Plenty of people get tired and make lazy shifts if the shifter is too far in any direction you get false neutrals.

2. Has the bike been over on the left side ? You can hit the shift arm and cause the arm to go out of adjustment, just have it re-adjusted 1 hour max.

3. has the shift arm been checked for wear? the arm can get worn from hard shifts and once worn will over travel and lock up at times.

4. Has the shift arm spring been checked to be sure it is not broken? Happens some times.

The shop that did the work should check things out for you and if there is something related to either the work you had done or the parts you had replaced. they should get the work warranted. Ducati parts have a one year warranty, regardless of the bikes age. ducati should also stand behind you with covering labor if it was due to a failing replacement part. If the shop screwed up they should step up and take care of the problem.

Good luck

Just got my bike back.  The mechanic said that it was the a shift fork again.  That's the second time in two years.

You may also want to bleed the clutch line just to be safe.

A bubble in the line will cause periodic hard shifts, false neutrals (due to poor engagement/disengagement), and just overall weird tranny/clutch behavior.  :-\

Mine has had a bubble in it ever since I installed my pressure plate. Some days it's fine, and others it feels like I'm doing damage to the gears (unlikely, but still annoying).

If the bike was repaired under warranty 8 months ago and you have the same problem it should be covered under warranty again. for two shift forks (must be shift arms) to go that soon something is not right.
Did you get a receipt with part numbers changed?

I've blown shifts, mostley from 5 to 6. and sometimes my foot gets a little jumpy and I click up before grabbing clutch.
08' S2R 1K   That was close  damn near lost a $400 hand cart.

lol... thats called a speed shift and if you just time it with a little throttle action you don't need to use the clutch.

I know I have said most things are in the adjustment but i do want to be clear that ducati does mess up every so often. My 97 m750 had poor gearbox shimming , when the motor would get really hot the gear engagement was off and you literally could not shift from 4th to 5th. this only happened at high speed tracks , never on the road. It did require me to go in and re-shim the gearbox to fix the problem, problem solved.
