CNC improved Vespa PX/T5 selector box


SLUK are supplying KR Automations to the UK market to make them more accessible and easier to order. We can get any of their parts, from Vespa stand feet to a full billet engine case. Just ask if it’s not listed.

The quality of later PX selector boxes was questionable and aftermarket replacements are even worse. KR Automations have sorted many of the problems with them to give increased reliability and smoother gear selection. German precision engineering.





KN’s solution is to obtain OE-quality selector boxes, strip them down and remanufacture many of the critical components. The connection to the internal arm is no longer a tapered-pin, it’s now a precision fit onto the shaft and retained with a screw. The notches in the selector wheel are all re-machined by CNC to improve the accuracy of selection and finally, the wheel and shaft are welded into position in a jig to ensure perfect alignment. Both early (up to ’83) and late (EFL/T5) versions are available.
