Stage6 R\/T high-end crankshaft with 90mm connecting rod<\/h2>\n

Stage6 R\/T crankshaft with 90mm connecting rod \/ 44mm stroke for 50cc motorcycles with Minarelli AM6 engine, high-end long-stroke crankshaft for racing.<\/p>\n

Advantages of Stage6 R\/T racing crankshaft<\/h3>\n

Elaborately balanced high-end racing full circle crankshaft with tungsten inserts.<\/p>\n

The tuning crankshaft is characterized by precise manufacturing and adherence to tight tolerances. The CNC-milled connecting rod is extremely durable and offers maximum strength for use in high-revving racing engines, while at the same time optimizing the flow characteristics.<\/p>\n

The very precise balancing via high-quality tungsten inserts prevents strong vibrations and ensures optimally smooth engine running. The crank pin measures 18mm instead of 16mm, the crank webs have an increased diameter of 77mm; both increase the load bearing strength and durability of the crankshaft. It goes without saying that the needle bearing is also of the highest quality.<\/p>\n

Compatibility and installation of S6 racing crankshaft<\/h3>\n

The racing crankshaft fits the Stage6 R\/T 95cc AM6 cylinder<\/a> perfectly, but is also a good choice for all similar high-end cylinders<\/a> with 44 mm stroke \/ 90 mm connecting rod.<\/p>\n

Plug & Play Installation<\/strong> – The Stage6 R\/T crankshaft can be installed without further modifications, without the need to mill the crankcase. We recommend using a set of new crankshaft bearings<\/a>.<\/p>\n
