Large diameter is very easy to grip. Very comfortable.
Not as well detailed as the discontinued Sunline Grand Touring grips but similar shape. The surface is tacky like those Sunline grips although the texture is different. The result is that my hands stay relaxed.
They went onto the handlebars about like any other grip. No problems here.
I bought these grips because I thought they would look good on my vintage Yamaha. These grips have an air gap between the part that holds the bar and the part you grab. The inner and outer parts are only conected at the inner end. I was able to install the left grip ok. When I was trying to put the right grip on, the inner part kept getting bunched up in the end of the bar. I tried to pull it off to see what was wrong and the outer half tore off of the inner half. By the time I got it off it was in four pieces. I have installed many sets of grips over the last 30 years, and these are the only ones I have ever broken trying to put them on. Unbelievable.
