The models used are V7special850 and ST400tempter. The Right Grip with a built-in switch is Refreshing, and the Throttle pipe integrated with the Right Grip is good because the bond is peeled off and there is no gap, but the smallest take-up diameter available is 34mm, which is Large. The Large size is 34mm at the smallest take-up diameter, which is heavier than the 32mm that I had been using. I think many people are pleased with the grip diameter, which is thinner than the previous ones, but it is too thin for my hand, making it difficult to ride, and the throttle is heavier due to the relationship between the rewind diameter and the grip diameter. However, the clean look is good.
