I can help somewhat possibly on the clutch issue. For small hands you are out at your finger tips when you start to pull the clutch in. My wife had to roll her hand forward to reach the lever and it left her with a very sore thumb. Below is a text from a posting I did a while back.
I can solve one hand....the left hand. My wife had the same issue and the biggest challenge came in operating the clutch smoothly and not ending up with a sore thumb from rolling her hand forward to stretch for the clutch. We tried to adjust the clutch with more play to bring the lever (and feather point) closer to the grip but that leads to not fully engaging the clutch and makes for tough shifting which is hard on everything.
Here is how we fixed that. I ride many bikes one of which I had just put new grips on. My old ones were smooth black ones. All my bikes have 7/8" bars. What one needs to remember is the throttle side of a bike is always 1/8" bigger than the clutch side. So my grips I had just taken off were 7/8" and 1" inside diameter. They were from a sport touring bike so they were smaller outside diameter than cruiser grips usually are. That last point is key.
Now S40 bars are 1" and then the throttle side is 1-1/8" id. This is typical of cruisers. That combined with the typically larger OD of grip leads to some very big grips for little hands.
What I did then was to take the throttle grip from my sport touring bike (which would have a 1" ID) and slide it on the clutch side of the S40 which like I said has a 1" bar so it fit beautifully. It was smooth black and no end on it since the Triumph has bar ends so I just popped the stock S40 end cap on step 1 is done! It is smaller in OD than the throttle side but looking at the bike you never see it.
Now step 2. Since the grip is smaller a small hand can reach further around and past it out to the lever. That is win #1. Win #2 and step #2 is to adjust the free play in the clutch cable. Where I said above you get hard shifting because your don't fully engage the clutch doesn't happen at the same point now. It did with the stock grip because it is larger in OD and limits how far you can pull the lever. With the smaller OD grip it allows you to pull the lever farther making up for the added play you put in the cable. Win #2!.
So basically you give her a smaller grip and this allows for better reach and couple that with a longer lever throw allows you to put a little more play in the lever to bring the feather point back just a little but you still have the stroke for full clutch engagement for smooth shifting. Combined we had a very successful mod!
She then proceeded to put 6500 miles on last summer!
Now this next section is some additional detail that was asked about the grips.
I have yet to find "small" grips for 1" bars which is what most cruisers run. What I used on my wife's bike was the throttle side grip of the Pro Grips 780 superbike grip set PG780bBX.
http://motorcycle.chaparral-racing.com/racing/Pg780bxI put the throttle side grip on the clutch side of the S-40 and left the S-40 throttle stock. It is larger diameter but she doesn't have any issue with the brake. The larger throttle will lead to less hand fatigue on long rides.
let me know if you have any questions
