Don't get me wrong EB, my style matches the moment.  Clutchless shifting is more or less limited to getting to freeway speeds from a dead stop.  But I enjoy a good rumble pop shift as well as the next guy.  And don't have the nack for downshifting.  But being able to do it, got me home one night when my clutch went out.  And does save your clutch hand when riding in traffic.

My maternal grandfather started out on bikes before WWII.  Moved through souping up Allisons and other aircraft power plants, then into race cars.  He could drive.

His shifting technique in a car was the most gentle I've seen.  He'd just whisper from gear to gear.  While this sounds slow, he was also more than quick enough for quite spirited work.  I'm sure he was just as gentle and precise on motorbikes.  

That's how I tend to shift - with as little force and as careful matching as possible.  It works.  I have a BMW with about 300,000 miles on the original clutch, and a Ford Ranger that got a clutch just because it was out at 175,000 miles - with 80% of the disk live left.  

I can shift a car without a clutch.  I just don't.

On Suzi, I find that the the trans is pretty light, things spin up and down pretty easy.  So a quick shift is cleaner.

I understand the polishing of touching clutch components.  That makes sense.  I can feel the stick sometimes.  I found the change to synthetic oil greatly helped the shifting.
