The legendary full cheek crankshaft suitable for mopeds / mopeds with Sachs 50/3 engines (not to be confused with 503 engines), which have L17 crankshaft bearings.
High-quality, precision-fit crankshaft weighing 1062 grams, which has proven itself in various load tests.
This crankshaft was designed for use in engines with a large increase in performance.
All balancing holes in the cheeks have been sealed with aluminum inserts for maximum pre-compression.
The solid connecting rod is equipped with a more stable 16 mm connecting rod pin, which is hollow on the inside for better balancing.
Dimension:
The needle bearing (12/15 x14.7 mm) is included in the scope of delivery.
You can find the matching bearings and oil seals in the accessories section.
Installation tip:The transition between the crank webs and cheek pins is provided with a slight radius for reinforcement. To ensure clean spacing, the first spacer washer should be provided with a slight chamfer on the left and right. This then lies neatly over the chamfer and centers itself perfectly. The other spacers can be used as normal.
You can find spacers and the matching bearings in the accessories section.
Quality product from the Portuguese manufacturer Rito.
