I had a new in bag set of Original Grip Buddies which wrap around the handgrips and provide some vibration damping and cushioning.
They work great in the rain, and will last a full season.
I don't need them, and if you like them they have a newer version with denser rubber and you could try that.
All I want is $4.90 to flat rate envelop it somewhere in the USA.
I had these on my C14 when I rode to Arkansas from MD and back and they helped my gimped arms and hands a lot.
So anyway, a really cheap way to see if you like them, and if not, not much spent finding out.
Can just paypal me, PM me and I'll give PayPal email address, since I will pay USPS by PayPal and it just zero the balance out.
