We usually recommend a new throttle sleeve when purchasing our Galaxy Grips. Many of the throttles on bikes are old and worn and have raised sharp ribs and diameter changes near the housings. These are all a major issues for our modern Galaxy Grips grips which are engineered for a super tight slip resistant grip. If you are going to put a nice set of high quality grips on your ride
then you should have a nice throttle tube to support them!
The Biltwell 7/8 size is only available as a full throttle kit because the throttle tube itself is not available.
