Smoother clutchless upshifts

I think it may be like Pantine Shampoo... it won't happen over night, but it will happen.

I have yet to see any owners manual/handbook that advocates the practise of clutchless changes.

Apparently at least one owner's manual does reference it, though I wasn't able to find a PDF of one to verify:

Smooth or not you are imposing all sorts of extra stresses and strains on various g/box and drivetrain components that would not otherwise be there if the clutch was employed.......not good.

From what I've read and heard about sequential transmissions (what we, the GSXR, and pretty much all bikes have), that's exactly what they're designed for. I can't say that I understand the inner workings well enough to know if using the clutch properly wouldn't extend its life, and I'd love to see something official or hear from an expert on the subject, but it was designed FOR clutchless shifting. And done even semi-correctly, it doesn't require any more force on the shifter and there's nothing to indicate that the trans doesn't love it. Just smooth, nearly uninterrupted acceleration!  

Track guys run them for years and years with untold number of clutchless shifts (some even downshift them too) and I assure you, rebuilding transmissions isn't something that happens often at all. Personally I've had my GS for 2 years, approaching 10k miles with something around 2000 of them track miles, and the trans shifts just as well as when I got it. (Motor hasn't needed a valve adjustment yet either!)  And I'm far from perfect, it's seen plenty of botched and jerky shifting and still does. It is still my first bike after all.

I mean, technically SHIFTING isn't "good" for the transmission, and running isn't "good" for the engine, but that's what they're designed to do!  


(I wish we could put this one to bed, this topic is done to death both here and on just about every other bike forum, but alas, I am not the expert it needs)

There are advocates for clutchless changes and there are advocates against. It boils down to good old "mechanical sympathy", some people understand, appreciate and practise it, and some people errr.......dont. The choice is up the individual
