Look how the Highway patrol in your state sits. I set my bike up to ride like they do. You can do 500 miles a day like that. The seat and bars need to work together. But I am not trying to look cool just ride as long as I can.

Upside down clubmans work perfect for me.

A little forward lean but not too much pressure on the hands.

Bars are a pretty personal choice, and depend a lot on your height, arm length, and foot peg position.

Learning not to squeeze so tightly helps.  Better grips and relaxing your hands will not eliminate it but will help out quite a bit

 The throttle return spring on my 78' 550 is waaaaay to heavy to not squeeze the grips. Without squeezing, the throttle returns to 0. No way around having to squeeze the hell out of the grips for me.

The bars the PO had on my bike have quite a sweep/pullback, and I find the same things as OP: my hands are at a funny angle with the bars. You want straight wrists, or like me, your hands will be shoved into the "pocket" in the grips. This, combined with the seams of my gloves, causes a pinch along the bottom of my thumb.



I am ordering Euro bars from vintagecb750.com this week (slightly more narrow and straight compared to their superbike bars).

Hey Mick. I've found that pain in the hands and wrists is usually caused by improperly positioned bars...

I'm glad somebody else mentioned this.
For me just changing the position of the bars a little bit ... makes a BIG difference in the angle of your arms and wrists when you're holding the bars. Once I found my angle... everything fits perfectly. Had to adjust a couple of times to get it just right.

Also... I think the stock set up is the MOST ergonomic.

These are the exact same grips I have on my bike and this is the exact same issue I am having. You nailed it.
I ordered some new, smaller and lower profile grips. Should be here Friday so we will see if they help before I change out my bars.

Also going to tinker with the angle a little more.

see, that's the thing...everybody's body is different.  I am kinda short and so are my arms, and that makes the stock american market cb bars too high for me...they put my hands almost at the level of my shoulders.  That makes my hands fall asleep and my shoulders get tired quickly.  I have a cb750 with clubmans and rearsets and a cb550 with stock riding position and I can honestly say that I am more comfortable for longer on the 750.  I will probably try some superbike bars on the 550 if I keep it long enough.  The ideal situation for finding what fits, is to have lots of different bikes to try...

Those grips have always been known as "Big Titty Grips" they are period correct, but not comfortable for some.

Ha Ha! They're the same as Besson grips over here, but I will refer to them as Big Titty from now on!

I put Big Titty grips on all my bikes, regardless of the bars. My ageing wrists appreciate not having to wind the throttle open so much to accelerate, and the skinnier standard grips make my hands hurt after a while.

Just goes to show how subjective and individual this is!

The bigger circumference of those grips means you actually have to turn them further not less.... ;)  They cramp my hands, I used to like the foam grips but they wear out faster...

Bloody Nora, you are right of course, don't know what I was thinking there. Clearly it's not just my wrists that are ageing!
I do find the fatter ones more comfortable though.

I initially had soft foam grips on my 550 but because of their softness I found myself gripping the bars tighter than I normally would just to get a feel for the bike and hands ended up cramping fast not to mention they weren't very durable. I switched to a much firmer/higher density foam grips and that's done the trick and they're pretty durable. I know there's probably a better grip available but the biggest problem I have is deciding which to choose because there are so many to choose from and you really wont know how the grip will work for you until you actually install them on your handle bars.

While I have no problem with Big Titties  ;D,  I personally use Gel grips. The set I have now are for Motocross I beleive. They have a high friction surface so I do not have to squeeze as hard.

I do find the fatter ones more comfortable though.
Me too.  The fatter ones also make it easier to overcome the throttle return spring.  Less fatiguing for me.  I don't get hand cramps with them.  Never has for 40 years of riding.

Larger grip = more leverage.

Since the '78 has twin cables you can install a lighter return spring to reduce the amount of force needed to hold the throttle open.

I guess we have different types of wear and tear. Trail and error until you find the right combo.

Equals more distance to turn the throttle, unless the throttle is heavy there's no advantage at all..... And if the throttle is heavy then fix it.... ;D

If that spring is so tight that you have to really grip the throttle hard then stretch the spring just a little bit. A very little bit goes a long way. I stretched mine maybe a couple of mm's in length and it is relatively easy to twist and still snaps shut definitively. I actually had to get used to the feel, those first couple twists came way easier.
