Repeat... Do not downshift... again, again... While kicking oneself in the butt ... then repeat, repeat.. repeat
New input transmission shaft $2,000 +
Do you blip the throttle to match the downshift or just downshift?

I agree downshifting is a normal function. If done right it should not be an issue. Now you probably shouldnt be downshifting IN a turn because that might cause control issues. But it shouldnt hurt the transmission per se.

Bad downshifting is a clutch life issue not a transmission/spline issue.

As an inveterate downshifter, a friend once pointed out to me that brake linings or pads are a lot cheaper than a transmission.
BMW once pointed that out to one of their race car drivers...can't remember, but back sometime in the '70s.
Sorry to hear that, but I don't think it was caused by downshifting. I think it sounds like a classic "transmission misalignment causing clutch splines to slowly devour the input shaft." Also, I'm sorry to say it is proablaby gonna happen every 30K miles until you sell the bike or replace the transmission.
Sorry,
Sorry,

On what? The guy just keeps saying "do not downshift." Heck, you upshift, you gotta downshift at some point. That's my take on it.

Methinks this is how the old never use the front brake myth got started as well.

Now that's the most intelligent answer posted.
This would be a manufacturers defect; Jim do you know of any successful claims on the manufacturer for this?
I haven't spoken to the tech yet, I'll post when I pick up the bike
Hmmm... I haven't noticed any clutch chatter. If misaligned that could result. The throw out bearing would be toast.

In 500k miles I've never worn out a clutch -- and I've put about 100k miles on three of them. I've also never worn out a clutch in a car. (When we put a rebuilt motor in our '86 Mazda 626 with 180k miles on it, the mechanic asked if we wanted to put the old clutch back in as it was less than half worn.)
Just as you should practice your braking skills, you should practice your shifting -- especially downshifting. You should be able to downshift even into first (at an appropriate speed, of course) while riding smoothly, without chirping the rear tire.
If you ever take one of Reg Pridmore's CLASSes and get to ride on the back of his bike, you'll notice that you can't feel him shift gears, he is ultra smooth.

I did once. It felt like his K-bike had a CVT in it! Amazing!
