REINFORCED CRANKSHAFTS
Wide selection of reinforced crankshafts for 50cc motorcycles, scooters, and mopeds
The crankshaft transfers the engine’s power to the transmission. Working closely with the cylinder, it is heavily stressed and may need to be replaced with a reinforced crankshaft to ensure greater reliability. In our online shop, you’ll find a large selection of reinforced crankshafts for mopeds, scooters, and small motorbikes, divided into two categories: Sport/Racing and High-End. All products come from top brands and offer excellent value for money.

Reinforced Crankshaft = Greater Reliability
When you get a new bike, it’s equipped with an original crankshaft designed for normal everyday loads. If you increase the engine’s displacement, it’s worth replacing the crankshaft with a reinforced model better suited for sporty or racing use.
Among our reinforced crankshafts, you’ll find full-circle designs with standard stroke and reinforced connecting rods – ideal for 50cc and 70cc sport cylinders. For high-performance setups, we recommend racing or even high-end crankshafts. Racing crankshafts are typically full-circle models with 10mm or 12mm piston pins and reinforced rods, providing strength and durability with 50cc and 70cc racing or high-end racing cylinders. The materials used and precise balancing make these crankshafts proven components for high-performance engines, thanks to their excellent reliability-to-performance ratio.
The reinforced crankshaft plays a crucial role in the smooth operation of your scooter or motorcycle. Matched to your setup – including cylinder, exhaust, and carburetor – it ensures greater reliability and extends the life of your engine.
