I've been using the Kury ISO's for years and years, and I like them, even with my small hands.
Some say they feel like coke cans; well they are bigger than stock, but not as big as coke cans.
This is similar to seat choice..... individuals differ.
Kuryakyn makes a set specific for valk that are extra long at like 6 1/4 inches (with drop in spacers) that work with your existing throttle sleeve. The 4-screw end caps make it easy to remove and replace, if you have to for some reason. But you can order a standard set for metric 1" bars that are the usual length of 5 3/4 inches if you want to. I don't need the whole long grip for my small hands, but I like the extra long ones so the throttle boss down at the end never interferes with normal riding. When I want to use the boss, I just slide my hand down to the end of the grip.
I also like that the Kury ISO's can have a throttle rocker/boss installed on the throttle grip. (I think there are several choices now) Here is a standard 5 3/4 inch grip with throttle boss.
The chrome on mine is fading after 10 years (I don't care), but they come in all black if you are worried about that. (but I don't know if the 6 1/4" valk-specific grips come in black) (see what I mean by the boss maybe interfering with the grip in the normal 5 3/4" grip?)
Here's a set with the Madco Rider throttle lock added (which I have on both bikes).
Besides Kury, I have looked at these SAC grips several times. Real leather (which wears out more than real rubber).
