Those grips use Biltwell Aluminum Whiskey throttle sleeves as a base --- Hermann Oak leather is then cut into 1/4" lace, wrapped and glued around the throttle sleeve. In this case you would have to cut one of the throttle sleeves down on the end to use it on the clutch side. The throttle sleeves are about $49.00 a piece.
Alternately, you could purchase a set of straight billet grips and then wrap them yourself, or you could purchase a set of grips with one piece rubber sleeves, remove the rubber sleeves and wrap them with your own choice of leather.
Finally, you could just purchase a set of theirs for $369.00. Note: Theirs will only fit 1" bars.
Good Luck! I hope that helped.
