Thanks to the various adjustments and two different mounting kits, you can install it on all carburetors on the market and, with an almost original throttle grip stroke, manage from the classic 24 to larger carburetors like the vhsb39. In addition to keeping the handlebar of your Vespa original, you can allow the sheath to take a much more linear path and at the same time have a quick release of your carburetor. The kit will include everything needed to mount it on both the classic phbh or phbl, and for the vhsb with a plastic cap as well as for the vhsb racing or vhsh with an aluminum cap.
