Speed shifting?

I've been reading Proficient Motorcycling (thanks for the pointer, Theauhawk!) as well as other, similar, sources online. One of them stated that modern bikes are built to speed shift, and that it actually provides less wear and tear on the clutch mechanism:

"To change gear we roll off the throttle and pull in the clutch lever, kick up the gear lever then engage the gear selected by releasing the clutch lever and rolling the power back on.

There is another way when changing UP from 2nd gear and above:

Leave the clutch lever entirely alone. Roll off the throttle and kick up the gear lever then re-apply the power. Modern gearboxes are so smooth that a slight closing of the throttle will enable you to change gear smoothly without using the clutch.

Many gearboxes will allow you to change down without using the clutch but this is generally less smooth.

If you intend to try this for the first time then start by changing up in the higher gear ratios first rather than from first to second. For example: change up to fourth in the normal way and accelerate to the speed that you would normally change to fifth. Roll off the throttle and immediately kick the gear lever up to fifth and be ready to roll on the throttle soon after that!

Advantages of the clutchless gear change is that it is quicker, smoother and less wearing on the mechanics of the bike."

Quoted from http://www.datacraftsystems.co.uk/te...hniques_right/

Now, I have been speed shifting my car for years, and never experienced a problem...I'm wondering if there is any validity to this quote, and whether anyone actually does it.

Edit: A buddy of mine owns a Shadow, and sent me a link to a discussion on their forum of this very subject:


It appears that there are advocates on both sides of the debate, but all in all, the bottom line seems to be that as long as you are not grinding gears, its not harmful, and any wear on the gears over time is so small that you probably won't ever notice it.

I will leave that type of shifting to the 18 wheelie. Chances are that it is okay but I don't want to find out for myself.

I do it quite often, as well as downshifting without using the clutch.
I too feel that if you're not grinding anything, you're not hurting anything.
And even then, it seems that usually, if ya don't get the shift at just the right spot, you're not going to grind, you just don't get it into gear.

One time a buddy bet me that I couldn't go from running speed to a stop without using the clutch. I did it easily, all the while my left hand never even touching the bars just so he knew I didn't use the clutch.

Well as an experienced 18 wheeler driver, I can tell you that you need to be at or close to the sweet spot. Or as hyperbuzzin say's 'the right spot. That's usually fount at low RPMs just above where the engine would lug. Have done it many time in a tractor, I'll have to try on the bike, carefully.

no cluth?

i too over the years, in a truck, vw, and motorcycles have shifted clutchless. in my opinion if you would like to try this, try it on shifting up; roll off ,shift up, roll on, in a smooth motion. :" speed" shifting up is not as much a consideration. shifting down is at best a dicey situation because you cannot control the engine rpms to compensate for the gear ratio. in my opinion, as it can be done, it should be done at slow speed as indicated in earlier posts
