Foot starter shaft protection 139 QMB 101 Octane

I have been buying parts from gmoto for several years and I am very satisfied with the quality of the product, as it is made very solidly and aesthetically pleasing. The shaft protector that I recently bought fits perfectly to my 139qmb 4T engine

GY6 139QMB 101 Octane camshaft bridge

Motobi Huzar 4T 50cc. The product is solidly made. It is not a cheap Chinese product. Precise dimensions contribute to fast and trouble-free installation and operation.
