Clutchless shifting?

[wbks]

I also disagree, surely its easier to just roll off the throttle than it is to grab the clutch.

I thought this was going to be an easy concept to understand... Watch the video... At any point besides braking does it sound like his throttle isn't wide open? Seriously... People who disagree: Find ONE video of a pro mx/sx'er in recent years who rolls off the throttle to make a gear change while racing

Well I couldnt really make out what was going on in that video, so I googled it. One page was pretty helpful, seems you are right, and me and crasher may still be on the beginers shifting technique

I have noticed that a lot of beginning motocross riders often get pretty confused about how to shift gears properly. Everyone seems to have a different opinion and it can be quite difficult to find instructional materials that actually cover this important aspect of motocross technique.

There are two ways that I personally like to shift up gears on a motocross bike and I'm going to attempt to explain them in this short article.

For the first way you don't have to use the clutch. Basically all you need to do is back off the throttle, shift up and then get straight back on the throttle as quick as you can. It's ok to not use the clutch in this situation as the drive is momentarily disengaged.

This way is fine but since you have to back off the throttle, you will lose a bit of momentum and you can't afford to do that in a race.

There is a much more effective way of upshifting that will actually allow you to go much faster and you won't lose any speed.

All you need to do to is get the throttle pinned wide open, pull in the clutch just a tiny bit so that the engine is just about disengaged, shift up then let out the clutch. Do this as quickly as you can and make it one fluid motion. This will allow you to keep the revs high so that when you let the clutch out, the power is there right away. You won't have to wait for the power to dial in again as in the previous method.

Now, a lot of people think you have to use the clutch when downshifting but that isn't the case at all. When you shift down, there isn't anywhere near as much of a strain on the engine so it's not really necessary. In fact, by not using the clutch you are able to use the engines natural resistance to help you slow down (this is called engine braking). Ideally, the only time you should be shifting down is when you are on the brakes. Being on the brakes means that there is even less strain placed on the engine and the combined effect will allow you to slow down a lot more efficiently.

I hope this will help to clear up any confusion you might have about shifting properly on a motocross bike.

I suppose the clutch technique require a bit more skillful timing, Ill have to try it sometime, though atm on my list of things to improve, shifting isnt really on the urgent side

better off get a quickshifter

Mate...if you wanna totally fuck your transmission do as they say. Time wasting not using the clutch...frog shit. It takes a split second to crack the throttle off and hook the next gear...and who says drive/revs drop? Total load of shit. Ask Mick Doohan. never even used a speed shifter...and it makes no fucking difference wether you're racing in the dirt or on tar...I know this...done both. Crack the throttle off a split sec...hook the next gear.

Mick Doohan has fuck all to do with the argument. If you can find a quote from anyone from Daryl Hurley to James Stewart proving me wrong, do it. Totally wreck the trans? Me and everyone I know that races MX has put over 200 hours on single bikes doing this from stock, and besides top end rebuilds and box oil changes they haven't needed to touch it. Are you going to tell me it wears out your tranz oil faster? You really need to try it some time, it will help. And yea it does actually make a difference dirt or tar. When was the last time you fanned the clutch out of corner on a litrebike?

Neither Daryl Hurley or James Stewart are good enough to lick Doohans balls yet. The original question (I belive...without reading it all again) was harm to the trans doing clutchless upshifts? Interupting the power delivery by pulling the clutch but keeping the throttle pinned will send a nasty jolt through the trans every single shift....and it's NO quicker than cracking the throttle off.

WHAT do you think an electronic speed shifter does on a RR bike mate? Interrupt the ign for a mill sec to take the load of the trans so you can keep it pinned and hook the next gear? Bit like cracking the throttle off eh? I've got an RMZ450...if you ever want to see what's quicker in a stright like no worries...we'll have a few side by side race strats to see.

And fan the clutch of a litre bike out of a corner? Whe're not talking fanning clutches out of corners...we all do that on dirtbikes...well different from doing so when changing gears though mate.

The threads about sports bikes from a road rider wanting advice.In the name of making things last reduce throttle and use clutch.Reduce the impact of horspower on moving parts to increase life expectancy.Guys that race expect thing to break and explode at some point but im sure every road rider would rather not strip their engine every 2nd year searching for the damage they induced by riding hard to win races.
Its not a race and bikes are fast enough to enjoy without giving them death every time you go riding.Ride it like you want to keep it forever.

You guys riding mx bikes do so on light bikes, on surfaces that allow for wheel spin and you dont try jarring 130hp when you shift gears.

Okay,thanks for the help and advice people.
I have tried what you have said and it does seem smoother on the Mrs, She didnt hit me in the back with her helmet once,at least not by accident

James Stewart is the fastest supercross racer in the world, Doohan used to be the fastest GP rider. My argument was that in MX you flatshift, you said that "dirt or tarmac it's the same deal". I'm sticking to it. If you are really willing to let me on your 08 rmz I'll be more than willing to show you the time saved changing gears, though! You shouldn't though, I might blow up ya tranny!

James Stewart has a fucking long way to go before he can even be mentioned in the same sentence as Mick Doohan. Ricky Charmichael maybe.

We'll have to agree to disagree on this...but you go get yourself a late model 450 to ride...I've got mine and I'm backing myself to dust you off in a drag race. In the dirt or on tar.

i shiftless up from 1st the whole way, even in town.

I'll clutch for all my down changes though.

[Chrislost]

well theres only one way, you shift with out using the clutch duh

You should know that using the clutch while wheelieing is looptastic

[Wren]

Whats a quick shifter guys?

And how do I get rid of my L-Plate Rider rating

you have to go sit the kb'r test, to ensure you fit in with the crowd, its kinda like a scratchy test, but on a computer. Dont worry if you fail, you can sit it once per day till you pass.
