crankshaft -NARAKU- heavy duty with 16 tooth oil pump driven sprocket for 139QMB/QMA

Description

For high quality tuning items NARAKU is already a household name in the 4-stroke market. The need for a durable quality crankshaft, which is also reasonable in price, has now been taken care of. The NARAKU shaft is produced according to OEM guidelines of Taiwanese and Japanese vehicle manufacturers. According to the requirements of big bore cylinders, the shaft is equipped with HD Heavy Duty quality needle bearings in the connecting rod area. This ensures significantly more load capacity and a longer service life compared to the original Chinese shafts.

The Naraku HD crankshaft is a few euros more expensive than a Chinese spare part, but anyone who takes the trouble to replace the crankshaft on their vehicle has invested their money well here. Nothing is more annoying than a defective scooter again after a short running time, because spare parts of inferior quality were used.

The crankshaft corresponds in dimensions and shape to the original part and is ideal as a spare part with a "plus" in durability for further tuning measures. The shaft is supplied with crankshaft bearings already pressed. Next to the shaft from Top Racing our favorite. And in price / performance first choice.
