High-end racing crankshaft compatible with your Puch Maxi S / N, as well as the Supermaxi LG1 moped equipped with a 1-speed E50 engine.
This high-quality, precision-fit, 968-gram solid-flange crankshaft—which has proven itself in a wide variety of stress tests—impresses with its excellent balance ratio and good rotational stability.
This crankshaft was designed for use in engines with significant power upgrades.
All balancing holes in the flanges have been sealed with aluminum inserts to maximize pre-compression.
The solid connecting rod is equipped with a sturdier 16-mm-diameter connecting rod pin, which is hollow on the inside for better balancing.
In addition, the connecting rod bearings are silver bearings, which offer excellent emergency running properties.
The needle bearing is included in the scope of delivery.
We precision-balance every swiing® “High-End” and “Wolfram Edition” crankshaft to within 0.02 mm for maximum smoothness and peak performance.
You can find the matching bearings and shaft seals in the accessories section.
A sophisticated product meeting the highest standards of the swiing® quality brand.
