nowhere did he mention competing in motogp or wsbk...

It's implied

i highly doubt he's racing in motogp or wsbk considering he just stated hes a new rider...
there is absolutely no need to use the clutch, especially with a slipper unless you're doing some insanely fast hot laps.

I'm one of those you're not supposed to listen to. I don't think it is a good long-term plan to be doing clutchless downshifts - it is hard on transmission dogs. It will work fine for awhile until it doesn't, then you're looking at a $5K bill to replace the dogs. Clutchless upshifts are Okay with good technique. There is a reason why BMW's shift assist is designed to be used ONLY for upshifts.

I have to admit that I don't really understand the issue with rev matching and downshifting. It's a heck of a lot easier on a bike than a car. You simultaneously roll off the throttle while you pull the clutch, blip the throttle to rev match, and then re-engage the clutch. I'm not God's gift to motorcycling, but I've been doing it smoothly on all sorts of bikes for my 43-year riding career and the S1000RR is one of the easiest.

+1. I've been doing just the same.
Clutchless dowshifts sounds like fun, but I don't have the guts to try.

can you please explain how exactly is it hard on the dogs?

Russian Thank you!!!
As soon as you posted the reply I went out for a 4 hour joy ride and tried your technique. It worked great from the 1st time.
Now after doing it about 100 times over and over, I don't even think about it and there is no "jerk". It's very smooth as long as you roll back on the throttle as soon as it "lets" you downshift...

This technique would OBVIOUSLY not be used on the track. When are you ever in 4th gear where you actually need to be in 3rd???

On the track downshifts happen during breaking in which the breaks, bliping the throttle and clutch are done simultaneously.

Thanks again Russian. Spaciba!!!
