"Short shifting" WTF is that?

WTF is short shifting? Do you mean shifting before the power/torque peak? SHifting at too low revs? I've been riding for over a decade and I still haven't had anybody explain WTF short shifting is despite them standing around talking about it.

Short shifting is what rattles you out of a slumber at 3am as that empty 18 wheeler goes up and down the entire 10 speed shift range with the frickin' jake brake still on despite the fact that it's a 30mph zone.

THose big trucks don't have even 2000 rpms to work with. Coupled with a close ratio trans and shifting every 300 to 400 rpms is a nessessity.

I don't see exactly how this could be bad for the engine, as long as you're not bogging the hell out of it or ramming down too many gears either. When you're cruising in 5th gear to keep lower RPM, you know you can only CRUISE. When you need to grab some torque you down shift. Properly done there's no way that could be bad.

Your sense of humor mimics your ability to proof read your own posts. I don't like your tweed sir, good day I say, good day!

If everyone just went and looked things up, 90% of the posts on this site would never happen - Still, sometimes people will ask about something that a simple web search would answer with ease, or post a question when there are three other threads on the same subject underway. It is generally polite to do at least a little bit of work before asking other people to make the effort to respond on your behalf.

I can hardly believe this thread has gone on for so long when the question was answered three times and debated to death in the first page (dumbass assertions about gear dogs notwithstanding.)

Since lugging was briefly mentioned and the topic of oiling came up, it is my understanding that older boxers (airheads for sure) have very low oil pressure at low rpm. Supposedly, lugging the engine can overcome the oil film. Doing so habitually, leads to excessive wear in the big ends and/or main bearings.

Or you could just be polite yourself, ignore the threads you don't like and let everyone in peace answer and discuss what they want.

Then you have to wade through all these repetitive posts, most of which have been answered time and time again already, just to get to some new and interesting content. I bet you'll be sick of oil, tire, beginner riding tips, what bike should I buy threads, or am i doing xyz wrong/right threads soon enough. Just give yourself some time on the site...

the other concern from lugging would be pre-ignition, a higher octane gas helps avoid, almost every car on the road today has anti-knock sensors, afik, in bikes, that's not as common

On my Vee, a paved road I don't see top gear till 80mph on a gravel road, that comes at 65 on a frozen snow/ice covered lightly sanded road (as opposed to wet & slushy or churned snow on unknown underlying surface) top gear comes at 55 . in the more slick conditions when your front tire is pushing thru reistance ya can't really get to those speeds safely so I top out in 4th gear, it lugs to 30mph without resistance and increases smoothly up to 50 when I might think of catching 5th gear for a moment

The Wiki explanation is accurate, but doesn't cover every use of the technique

Back in the ol' days, the dirt bike magazines would talk about short shifting open class (500cc) dirt bikes. I assume the reason is because those bikes would fall off the power curve at about the time a 250 is coming on. So, guys accustomed to smaller bikes would need to break themselves of the habit (the habit of letting revs climb past 3000) in order to get the most out of the machine.

On a 450 thumper, I will sometimes take advantage of the soft power of the lower rev range by riding a gear high, eg - short shifting. It's handy if too much power would make the back end kick out or otherwise adversely affect handling. A quick pull of the clutch can then pick up the revs and get me back into the power.

I short shift for different reasons depending on the bike. On the 640 riding trails it is usually so I either don't kill myself and/or have a prayer of hooking up. If I let that bike get into the meat of its power on tight trails it either launches me into something, loops out or spins the tire. And having been pounded by the first two, I really try to limit how often I do them. So for the 640 it is normally to limit how much power I put to the ground. For the street it is usually for wheelies.

On a bike like my 200 that has a very hard hit when it comes on the pipe I usually want to hit a turn or a jump a gear high to avoid having it come on the pipe mid turn or off the lip of the jump. Either of those scenarios can be exciting. See above about hitting things and looping out. For my riding style a gear low is better than a gear to high because it saves a shift and a quick fan of the clutch gets it back on the pipe. The 200 isn't very powerful lugging but it is nice to NOT come on the pipe in some situations.

I learned to ride in deep sugar sand where short shifting was the fast way around a track or down a trail. The best way I found to hit those soft berms was to short shift into the turn then use abuse the clutch out of the turn. That kept you from blowing through the berm or spinning the tire too much on the gas and saved a shift on the next straight. It uses the clutch like an automatic transmission to modulate power and save a shift. It is magic when done right in loam and sand.

What most fail to understand ^: is that short shifting with dog ear gears will destroy your driven gears in a very short(pun intended) time, so unless you have straight cut gears, or you like ruining your trans! I would suggest winding out your shift to there intended tolerances, or at least close to them! It is also very hard on the Clutch plates.
