    I have a bad habit. I downshift coming into a turn like I do with my manual trans cage.

    That puts extreme stress coming in then add digging out of apex, hmmm

    Repeat... Do not downshift... again, again... While kicking oneself in the butt ... then repeat, repeat.. repeat

    Do you blip the throttle to match the downshift or just downshift?

    As an inveterate downshifter, a friend once pointed out to me that brake linings or pads are a lot cheaper than a transmission.

    That's nuts. Downshifting is part of riding a motorcycle. Was the spline lube done on time?

    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.

    I don't know about the RS but my 1150R loves to be left in 4th gear for all but the tightest cornering. Good engine braking coming in, good launch out. On a twisty road I forget the shifting and ride her like a big scooter.I'm a pretty smooth rider in the corners..I practice The Pace

    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,

    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.
