High quality cast iron sport cylinder with a midrace port layout.

Excellent cylinder kit to give your jet wings The porting layout and the generously dimensioned channel areas ensure a significant optimized filling over the entire speed range and a significant increase of the nominal speed. Not only does this give you a significant gain in exhaust power, but it also gives you a good deal of flake at top speed. The porting layout is a poem and the 3-piece exhaust shape is only known from cylinders like the MHR Team & Consorten.
