On the street, I blip [or rev-match] downshifts all the time, save for going from 2nd to 1st.

In the dirt, I rarely ever revmatch, as the engine braking can REALLY haul your speed down fast.. dirt has enough grip to take it, and not send you sliding out [most of the time].

I agree on single track dirt, you use the downshift as a brake. It's sort of a weird art, but comes naturally when things get sketchy on a steep downhill, even for a few feet!

What ^^^^^^^^ he said.

I rev match religiously on my 700 lb street bike, even though it has a slipper. I shoot for automatic trans smooth upshifts and downshifts.

On my supermoto with a slipper, or dirt bike, not so much. Grab the gear you need and let it get loose!

It's become habitual for me to use my gears for "braking". *I would not call it braking, it is a way to get more traction and speed. It all depends on how it is administered, but you will not find me at 2,500rpm sneaking through traffic, 4,000 is more my deal, correct gearing is the only thing that can do that effectively.

I hope i can get some answers and discuss this ...



Thanks Sasha

The reason we do this is to save the clutch. If you match the engine spped to your road speed, you will not be "bombing" the clutch. It just takes alot os stress off the the clutch disk. Its very important in diesel engines.

On pavement you can do the same thing, its more to keep the rear end in line and not upset the chassis.

A perfectly matched shift right and tip-in while trail braking is a beautiful thing.

Obviously, I do not apply any of this to honest to goodness, real life, living and breathing top tier racers. They can do whatever they want if it wins them a race, but the average Joe emulating things used on a race track, on the street, is completely uncalled for and is simply douche. Just throwing that in there in case someone tries to tie performance into throttle blipping.


Blip, flip, skip to my Lou or doodly doo, whatever nets you the most enjoyment from riding your motorcycle, that is your right as well is mine to call DOUCHE. We all get to have fun.
O lawd...

There's a difference in rev matching and just cruising around randomly blipping the throttle. Assuming you know what the hell you're doing, a properly executed rev matched (blipped) downshift will put you exactly at the appropriate RPM for the gear you're shifting into. Engine noise shouldn't be much more than if you were just slipping the clutch... which will also increase engine speed.

I understand there's no requirement to have anything approaching justification to have an opinion, but I'm at a loss how you've come to the conclusion that what's being discussed here is "douche " behavior. Who deemed clutch slipping the only valid technique for the road and on what grounds?

Depends on the situation.

I have a corner a few blocks from the house (downhill, hard right hander) on the way to a gas station that I often skid the rear wheel through when downshifting. Usually, you want to keep traction when downshifting into a turn...

I don't think Onederer knows the difference.

I use the throttle to match revs between shifts all the time, except when coming to a stop, I downshift to 1st (with throttle closed) when at the speed that 1st delivers at idle. Perfect slick downshift.

Another forum I frequent had a story something like this:

A passenger commented to the rider that the shifts were so smooth on that particular motorcycle that they asked if the motorcycle had an automatic transmission!

Never.
I could not be bothered, and to hell with the clutch, speed shift, jam the shifter up and down, full throttle, abuse the thing, if it has problems I will fix it. (its never caused problems and I never wore a clutch out on anything modern)

I really have no clue how to ride, I don't hang off or rev match, I am too busy looking for cars pulling out, animals, the road surface, and enjoying myself.

Do the motocross guys rev match?
Maybe too much dirt riding?
Both our cars are manuals and I don't bother with them, but never tried speed shifting....

I tend to blip the throttle when I downshift, but it's mostly a habit from my early riding days. In those days I went everywhere as fast a I could go. I gotta say that when I match revs perfectly, it is a good feeling.

When I'm in close traffic and approaching a red traffic light I down shift not to slow myself down but to be in the correct gear for when the light turns green. Also I tend to approach red lights slowly because I'm too lazy to put my feet down. When the light turns green I'm not so quick to take off anymore. It seems like there's always some driver who is trying to run the yellow and ends up running the red. If you are blasting off the line at a traffic light at the same time the other driver is trying to run the yellow and is a touch late, you have a problem - car wins.

ABS won't do squat for a locking rear wheel caused by the engine.

It WILL open the brakes just enough to compensate for the engine braking.

A well synchronized downshift is quite satisfying, not to mention more comfortable and easier on various mechanical parts of the bike. More important is that if you make a habit of shifting smoothly you are prepared for situations where a smooth shift is critical. That could include the situation when you failed to judge what gear the bike should be in going around a curve and need to downshift mid-curve. Yes, I know you're not supposed to do that but I bet we've all found ourselves in that situation occasionally. If you can downshift smoothly with confidence it isn't a problem, but blow the downshift when going around a bend and it can end badly. Other occasions where it can matter is if you downshift on a sandy or oily spot on the road. Of course if you're going to carry a passenger they will most certainly appreciate smooth shifting. Also, as someone else pointed out, your ABS won't help if you momentarily skid the back wheel from a badly co-ordinated downshift. If it becomes a habit to do it right you'll never have a problem, and you'll enjoy it too.
