Holden · « **on:** July 21, 2011, 07:01:18 AM »

I've had two bikes with center stands in the past: a '72 CB350T and a '79 CB750F. Once I learned the technique, getting those bikes onto their stands was not a big deal. However, my '74 CB750 is another story. My bike is stock height in the front and rear.

I fashioned a ramp for the rear wheel from a piece of 2 by 12 by cutting one end with a circular saw at a 45 degree angle and that is the only way I've been able to get it on the center stand. I have a 4 into 1 exhaust so the stand is easy to remove/install as needed.

Lift straight up grasping the frame under the seat on the left side with your right hand and pull back on the handlebars with your left hand. You have to do it like you mean it. Think, kick starting an old Shovelhead, or shooting a home invader with a 12 guage, like you mean it.

+1 on KCC

I have '74 CB750 also. With the bike turned off and in first gear I step down with all my weight on the center stand, pull the clutch with my left hand, and pull up on the grab bar close to the shocks and the bike pops right on the center stand with just a little effort.

good luck

I've been successful with my K1 and my BMW (it's an absolute BEAR to get on the centerstand) by placing the primary emphasis on getting my weight (~185 lbs) sharply on the centerstand tab and using my hands/arms primarily to stabilize the bike while giving it a pull up and slightly toward the rear. Use your body weight to lift the bike, not your back and arms.

I tried to do it like I mean it. I'm not a big guy (5'9, 155 lbs.), but I'm in pretty decent shape and this bike resists my efforts to get it on it's center stand. It does have a 16" rear wheel with 130/90 tire, but the way I calculate it, that should be within a 1/10 of an inch of the radius of the stock wheel and tire, so no real effect on rear ride height.

Holden has the right idea. Here is a video of my XS650 that also has a 16" rear wheel. Yamaha did not change the design of the center stand when they switched from 18" to 16".

I just place a short piece of 1 X 2 behind the rear wheel:

The piece of wood is small enough that I can take it with me on a trip.

I use the same technique with my CB750K-4 and CB750C. I also do the same with my CB450 Twin and it is the most difficult to lift, even tho it is the smallest bike in the stable. Honda just located the center stand in the wrong place on the frame on that one.

Sounds like someone needs to put her purse down and man up on that bike. That's your horse tie her to a fence and put her on that center stand!! Maybe princess should trade the bike in for a Vespa scooter, oh wait they have center stands too....

Have you thought about putting your hair in a pony-tail and removing your fingernails to get a better grip? Or maybe wearing your 4-inch heels to get some leverage on the bike....just trying to be helpful here

Sounds like you have tried all those things....

Which one worked best for you?

Duke McDukiedook · « **Reply #9 on:** July 21, 2011, 08:06:01 AM »

Push down with your right foot while lifting the frame up with your right hand. The CB750 stock requires a little more force than modern bikes but it isn't that bad.

Holden · « **Reply #10 on:** July 21, 2011, 08:09:20 AM »

It seems to require considerably more force than my '72 CB350T or my '79 CB750F. And I don't think turning myself into a drag queen as markusarealius suggested would help. Although I'd be willing to try anything if markusarealius would answer Pete's question...

Not a CB750, but demonstrates the correct technique.

How to Use a Centerstand

Goldbug · « **Reply #12 on:** July 21, 2011, 08:45:48 AM »

The video above is correct but CycleRanger's explanation is wrong.

A center stand has a cleverly designed lever built in. The movement you want is pulling UP (and pushing down with your foot), NOT PULLING BACK. The lever moves the bike back when you pull UP, not the reverse of this.

If you are pulling the bike back then you're not using the mechanical advantage the lever provides.

You are correct.
I neglected the pulling up part, which is just as important as I have observed most inexperienced persons pulling back, not up, and not applying any pressure to the center stand.

Maybe if your thread title was more descriptive it would have helped.
Something like "Video needed of getting a 750 on the center stand"

Just a thought.

Holden · « **Reply #16 on:** July 21, 2011, 09:08:21 AM »

I've STFA. I just wanted to see what others said about the difficulty of getting the CB750 on the stand compared to other bikes. My experience is based on other vintage Hondas, which were much easier.

Goldbug · « **Reply #17 on:** July 21, 2011, 09:16:47 AM »

I don't know why it would be more difficult, Holden. Maybe a CB750 just has a noticeably heavier back end. Or maybe your center stand is bent, has a flat spot- something that's preventing it from providing that correct amount of mechanical advantage.

My CB500 has the rear grab bar removed so it's a little harder to get a good grip but being 250lbs and relatively strong I get it on the stand regardless. Back before I knew how the center stand worked I wondered how smaller people did it. I wonder if my 110lb girlfriend could get the CB500 up. It would at least be entertaining to watch.

I just got an idea for a new video. It's scantily clad, possibly oiled up women with fantastic bodies lifting classic bikes onto the center stand with rad music playing in the background.

My bike didn't have a center stand when I bought it, so I bought one on ebay. Maybe that's the problem...

markusarealius · « **Reply #19 on:** July 21, 2011, 11:41:31 AM »

Yes, I have tried all those suggestions I mentioned earlier.....

The most effective however is to place my mascara on the rear of the seat and put my hair in a barrette while standing on the center stand and pulling up and back on the rear frame.

Seriously, you can do it - I just like busting your chops....

MCRider · « **Reply #20 on:** July 21, 2011, 11:53:50 AM »

All correct. I also recommend subject lines that are descriptive enough to get someone to open them. Pet Peeve of mine. Should have model of bike, 3 to 5 desriptive words. No riddles or open ended statements.

As to the centerstand, I would add its a mental thing to a large part. And the mental thing is to concentrate on pushing down with the foot. The leg is the strongest part of the body. Since the centerstand can't actually be pushed down thru the pavement, the force will reverse up thru your back and the arm acting as hard attachment, lifts the bike. The force to make the lift though is from the leg. Not the back or the arm.

That's how i see it.

Isn't that how the subject line in this thread was? Should I have been more specific about the model? K4?

It's not quite that simple. Sometimes all it takes is a tire size change (inch to closest metric) or a slight shock length change to really make it a bear to pull up the stand. I've dealt with a few big brit bikes that are nearly impossible, because they sucked from the get go (reused parts from other models) and 'modernizing' changed the geometry enough to make it really crap. It's merely a simple lever, but if the geometry has changed for any reason, sometimes it can be a dog.

A good check is to see how far the bike has to lift in the process of putting it on the stand. You can measure from the stand pivot to the bottom of the stand, and measure from the stand pivot to level ground. This difference is the lifting height, and if it's looking absurd, you might have the wrong length stand.
