Stage6 R1400 MKII hyper-racing scooter exhaust for Yamaha/ Minarelli 50cc 2-stroke horizontal engines.

This exhaust is the result of a decade of development, redesigned and improved since the R1400 was first introduced. The MKII R1400 has an optimised expansion chamber to suit modern cylinder designs.

Carefully welded thin steel cones and the carbon fibre silencer remain from the predecessor, the race finish is retained. The un-lacquered exhaust is recommended to be oiled.

This is a high end exhaust for 70cc racing cylinders like Stage6 MKII, Polini Evo, Malossi MHR etc.
