Crankshaft

The crankshaft is a central component of every engine. It converts the linear motion of the piston into a consistent rotational movement. In doing so, it is exposed to high loads from combustion, friction, and temperatures. Weight and balancing also influence performance.

A defective crankshaft can cause significant damage, often affecting the crankcases as well. It should therefore always be in perfect condition and match the engine’s performance level.

To make selection easier, especially for mopeds, scooters, and 50cc gear bikes, we have divided crankshafts into performance categories. The key information can be found below.

Our crankshaft categories

As with cylinders and exhausts, which largely determine engine performance, we distinguish four categories: Original, Sport, Racing, and High-End.

✅ Crankshaft Original

→ FEATURES: Matches the manufacturer’s original specifications

→ ADVANTAGES: Cost-effective, easy installation without modifications

→ REQUIREMENTS: Replacement of bearings and seals recommended

→ WELL-KNOWN BRANDS: Motoforce, Standard Parts, Yamaha, Rieju

✅ Crankshaft Sport & Racing

→ FEATURES: Reinforced, optimized webs, special materials, stroke matched to cylinder size

→ ADVANTAGES: Increased reliability, improved pre-compression, improved torque and RPM range

→ REQUIREMENTS: Reinforced bearings. If stroke or connecting rod differ, modifications to the engine cases are required.

→ BRANDS: Stage6, Stage6 R/T, Polini, Malossi, Motoforce Racing, MVT, Airsal

✅ Crankshaft High-End

→ FEATURES: Heavily reinforced, optimized balancing, forged connecting rod, reinforced needle bearings, precise balancing with inserts, adapted stroke (stroker)

→ ADVANTAGES: High durability, designed for high performance, optimized output

→ REQUIREMENTS: Engine case machining depending on the model, reinforced bearings, installation by a specialist recommended

→ SPECIALIZED BRANDS: Stage6 R/T, 2Fast, Top Performances, Ottopuntouno, Polini

Summary:

As performance and displacement increase, a reinforced crankshaft becomes more important. Many manufacturers design their crankshafts to match their cylinders. Combining both ensures a balanced setup in terms of power, torque, and durability.

Why replace the crankshaft?

Like most rotating components, the crankshaft is a typical wear part. Technically, bearings, journals, and the small end bearing are affected the most. These can be replaced individually, but the process is complex and requires special tools, so the entire crankshaft is often replaced.

Typical signs include increased vibrations or unusual noises. Experienced mechanics may also notice a grinding sound. In such cases, the crankshaft should be replaced.

When tuning, the original crankshaft should be replaced with a reinforced version.

Crankshaft installation

Always use new bearings and seals. Proper alignment is important to avoid vibrations and damage.

IMPORTANT: If you don't have any experience, installation should be carried out by a professional workshop.

Crankshaft maintenance

Regular checks and timely replacement of bearings and seals are essential. Each time the engine is opened, for example during a piston replacement, tolerances should be checked.

Watch for unusual noises or vibrations, as these are often early signs of wear. If bearings make noise or the engine vibrates, action should be taken early to prevent damage to the cylinder or engine cases.

Crankshafts for scooters, mopeds, and 50cc geared mopeds: our range

In our shop, you will find original and reinforced crankshafts for common engines such as Minarelli AM6, Derbi Euro 2 / Euro 3, Minarelli horizontal and vertical, Piaggio, Peugeot, Peugeot 103, and AV7 / AV10, as well as others, including less common engines like Morini, GY6, or Sachs.

This also covers many popular models, with suitable parts for Rieju MRT, Beta RR, Derbi Senda, Yamaha Aerox, Piaggio Zip, Peugeot 103, or Piaggio Ciao, among others.
