don't pull the clutch in, just downshift using engine braking and don't pull the clutch in until you are about to stall it as you come to a stop
If you are not downshifting, and keeping the engine in power, if you have to move in a hurry you'll be dead in the water.

When coming into a red light, I just ease off the throttle and downshift when the RPM drops below around 2,000. If I have cars behind me, I often will touch the front or rear brake to light the brake light. On my Beemer, I had an accelerometer-equipped rear brake light that would light it based on detected deceleration. It is made by Admore and I'm thinking about getting one when I get my Tour Pack squared away.

Which involves no throttle blipping or claims of downshifting better when blipping the throttle.
Yes, I agree with you about matching gearing to the conditions. But thats a different subject than what folk are describing.
There are plenty of folk who think they are spinning up the input shaft of the transmission by blipping their throttle when they pull in the clutch. All theyre spinning up is the outer clutch basket. The claims of a smoother downshift is probably poor clutch modulation on the release.

I guess somebody needs to educate this guy that he's doing it all wrong...

Seems youre hearing normal downshifts, with the engine revving up accordingly. The engine gets bounced off the rev limiter on some of the downshifts.

Actually very good advice here, among all the fun...
The rev limiter will keep the engine from over-revving when you are accelerating, but it will not keep the engine from over-revving when downshifting.
It is possible to over-rev an engine with an aggressive downshift.... That can cause engine damage...

Pay attention to some of the onboard videos of James Hillier there on the Isle of Man TT. Especially the one’s giving a cockpit view.

I don't believe the rev limiter works during a downshift...
It limits the rpm by cutting off the spark and/or fuel... I forget which one... maybe both.
Downshifts cause a mechanical increase in rpms, not affected by fuel or spark....

Only time I hear the bike bouncing off the rev limiter is AFTER he has exited the corner and is accelerating.
